Description

USE OF SILICONES WITH ESTER FUNCTIONS AS ANTI-TRANSFER AGENTS IN COSMETIC COMPOSITIONS

The present invention relates to the use of liquid organopoiysiloxanes (silicones) with ester functions (acetoxyalkyls) as anti-transfer agents in cosmetic compositions. It also relates to a process for providing anti-transfer properties to cosmetic compositions by adding to said compositions at least one liquid polyorganosiloxane with ester functions (acetoxyalkyls), as well as cosmetic compositions, in particular in the form of sun gels, deodorants. , antiperspirants, make-up or care products, comprising said liquid polyorganosiloxane with ester functions (acetoxyalkyls).

In many cosmetic compositions such as makeup, deodorant, antiperspirant, sun protection, or care products, a recurring problem concerns transfer by contact with the skin or other surfaces such as glass, metals, fabrics , of all or part of the formulation, transfer often resulting in the formation of spots. This phenomenon also encourages repeated applications of product following transfer losses. Many silicones are used today to improve these antitransfer properties in particular in applications of the lipstick, mascara, and foundation type. On the other hand, these formulations have the disadvantage of having a drier sensory profile than the traditional formulations.

The Applicant has found that liquid polyorganosiloxanes comprising acetoxyalkyl functions in which the alkyl group contains at least 3 carbon atoms, were very particularly advantageous for imparting anti-transfer properties to certain cosmetic compositions, in particular to make-up formulations, while providing a sensory profile closely resembling that of conventional non-transfer formulations.

In the definition of the mole of hydroxy-alkylated polyorganosiloxane, the hydroxy-alkyl function will be considered as elementary entity. The acyl halide of formula XCOR "most particularly used in the esterification step is acetyl chloride.

The acid halide formed by esterification can be removed by entrainment using an inert gas, then by treatment with a base. After devolatization of the by-products, the polyorganosiloxane having an ester function can then be recovered by filtration, for example.

This process has the advantage of leading to polyorganosiloxanes with ester functions, of very high purity, that is to say products in which the overall contents of olefinic siloxane units and / or olefinic impurities, with undesirable effects. or capable of reacting, correspond to a number of α olefinic groups per 100 g of polyorganosiloxane with ester function obtained less than 10 ⁻³ , preferably less than ^{5 × 1} O ^{* 4} .

They have viscosities generally less than 5000 mPa.s. The term cosmetic composition or formulation means all cosmetic products or preparations such as those described in Annex I ("illustrative list by category of cosmetic products") of European Directive No. 76/768 / EEC of July 27, 1976, so-called cosmetic directive.

For good use as anti-transfer agents in cosmetic compositions, said polyorganosiloxanes with ester functions of the above formulas can be used at a rate of 0.1% to 30%, preferably from 3% to 10% by weight said cosmetic compositions.

The cosmetic compositions containing said polyorganosiloxanes with ester functions of the above formulas as anti-transfer agents, can be formulated in a large number of types of products for the skin and / or the hair (or more generally keratin), such as foams. , gels (especially styling), conditioners, formulations for styling or to facilitate combing of hair, rinsing formulas, hand and body lotions, products regulating the hydration of the skin, toilet milks, makeup-removing compositions, creams or lotions for protection against the sun and ultraviolet radiation, care creams, anti-acne preparations, local analgesics, mascaras, deodorants , antiperspirants, lipsticks and many other compositions of the same type.

Preferably, said polyorganosiloxanes having ester functions are used in cosmetic anti-transfer compositions for the skin.

Said cosmetic compositions may use a vehicle or a mixture of vehicles compatible with application to the hair and / or the skin. Said vehicle can represent from 0.5% to 99.5% approximately of the weight of said composition, preferably from 5 to 90% approximately. The term "compatible with an application on the hair and / or the skin" means here that the other vehicle does not damage or exert any negative effects on the appearance of the hair and / or the skin or does not create no skin and / or eye and / or scalp irritation. The vehicles compatible with the applications described in this invention include those usually used in cosmetic compositions for the hair and / or the skin, for example those present in sprays, mousses, tonics, gels, shampoos, or lotions rinse. The choice of the appropriate vehicle will depend on the nature of the ingredients used, and the destination of the formulated product, depending on whether it is supposed to be left on the surface where it has been applied (e.g. sprays, foams, tonic lotion, cream, or gels) or rinsed off after use (e.g. shampoo, conditioner, rinse lotions). Said vehicles can consist of at least one solvent to dissolve or disperse the ingredients used, such as water, Cf-Cg alcohols, and their mixtures (in particular water and methanol, ethanol, isopropanol, and mixtures thereof), or other solvents such as acetone, hydrocarbons (such as isobutane, hexane, decane), halogenated hydrocarbons (such as freons), linalool, esters (such as acetate, dibutyl phthalate), volatile silicones (in particular phenyl pentamethyl siloxane, methoxypropyl heptamethyl cyclotetrasiloxane, chloropropyl pentamethyldisiloxane, hydroxypropyl pentamethyl disiloxane, octamethyl cyclotetrasiloxane, decamethyl cycloxane hexamethyl disiloxane, octamethyltrisiloxane, decamethyltetrasiloxane) and their mixtures. All of the vehicles used can consist of solvents which are miscible or immiscible with each other. When the cosmetic compositions are in the form of sprays, tonic lotions, gels, or foams, the preferred preferential solvents include water, ethanol, volatile silicones and their mixtures. Foams and aerosol sprays can also use any propellant capable of generating the products in the form of foam or in the form of fine, uniform sprays. By way of examples, mention may be made of trichlorofluoromethane, dichlorodifluoromethane, difluoroethane, dimethyl ether, propane, n-butane, or isobutane.

The polyorganosiloxanes with ester function of formula (I) are particularly well suited for uses as anti-transfer agents in cosmetic compositions containing at least 3%, preferably from 5 to 90% of alcoholic solvents such as ethanol, propylene glycol , glycerol. Vehicles can take many forms, for example, the form of emulsions including water in oil, oil in water emulsions, and multiple emulsions. These emulsions cover a wide viscosity range, from 100 to 2,000,000 mPa.s. . These emulsions can also be delivered in the form of foams or sprays using either a device of the mechanical pump type, or in the form of an aerosol pressurized by the use of a propellant gas. They can also be rheologically modified (increase in viscosity) for example by the addition of gums, resins, polymers, waxes or salts.

In addition to said ester-functional polyorganosiloxanes of formula (I), at least 0.5% of at least one cosmetically acceptable ingredient may be present in said cosmetic compositions.

To further reduce the irritation or aggression of the skin tissue, it is also possible to add water-soluble or water-dispersible polymers such as collagen or certain non-allergenic derivatives of animal or vegetable proteins (wheat protein hydrolysates for example), natural hydrocolloids ( guar, carob, tara gum) or derived from fermentation processes and derivatives of these polycarbohydrates such as modified celluloses (for example hydroxyethylcellulose, carboxymethylceliulose), guar or carob derivatives such as their cationic derivatives or non-derivatives -ionics (for example hydroxypropylguar), anionic derivatives (carboxymethylguar and carboxymethyl hydroxypropylguar). Specific anti-transfer cosmetic compositions in which the polyorganosiloxanes having an ester function of formula (I) are used as anti-transfer agents, are those comprising an oily medium.

Among these oily media, there may be mentioned, for example, those whose main fatty phase is of the type

- aliphatic fatty alcohols saturated or unsaturated with Cg-C ₂₂ , preferably with C-j4-C ₂ o, optionally containing 1 or more oxygen heteroatoms

- ethers of polyethylene glycol or polypropylene glycol and fatty alcohols in C4-C22, preferably in C10-C20 - acetic esters of aliphatic fatty alcohols saturated or unsaturated in Cg-C ₂₂ , preferably in C- | 4- C ₂ o, possibly containing 1 or more heteroatoms of oxygen

- aliphatic diesters of C ₂ -CI Q dicarboxylic acids, preferably C ₂ -C ₈ - natural or synthetic triglycerides

- aliphatic isoparaffinic oils

- paraffinic oils

- polyisobutenes oils possibly hydrogenated

- mineral oils - low viscosity non-volatile silicone oils

The amount of polyorganosiloxane having an ester function of formula (I) which can be used in said oily media is preferably of the order of 0.2 to 50, preferably of the order of 2 to 10 parts by weight per 100 parts in weight of said oily media. A fatty phase is considered to be the main in an oily medium, when the latter represents of the order of at least 10%, preferably at least 40% by weight of said oily medium.

Among these main fatty phases, there may be mentioned in particular

- oleic alcohol - isopropyl adipate

- polypropylene glycol (PPG) -3 myristyl ether (WITCONOL APM® marketed by WITCO), PPG-4 myristyl ether, PPG-4 lauryl ether, PPG-10 ketyl ether

- mixtures of cetyl acetate and lanolin acetyl alcohol (CRODALAN LA® marketed by CRODA) - caprylic acid triglyceride

- corn oil

- grapeseed oil

- sweet almond oil - jojoba oil

- squalane

- optionally hydrogenated polyisobutenes

- petroleum jelly oil - paraffinic oils such as petroleum jelly oil

- isoparaffinic oils (MARCHOL 52® and MARCHOL 82® marketed by ESSO)

- dimethicones with a viscosity of less than 5000 mPa.s.

- phenyltrimethicone (MIRASIL PTM from Rhône-Poulenc) - diphenyldimethicone with viscosity less than 5000 mPa.s.

Oily media composed of mixtures of cosmetic emollients of the type of those appearing in particular in "Cosmetics & Toiletries" / No. 93, page 107-July 1992, are very particularly preferred.

Said cosmetic composition can be constituted by said oily medium itself, optionally thickened, or by a single or multiple emulsion "water in oil" or "oil in water", emulsion in which the oil phase consists of said oily medium optionally thickened .

Said composition containing said oily medium optionally thickened present as such or in the form of a single or multiple emulsion "water in oil" or "oil in water", may also contain other conventional additives for cosmetic formulations such as for example waxes silicones, non-silicone waxes or mineral derivatives. Said composition can also be a solid formulation which can optionally be shaped by molding, such as, for example, deodorants, antiperspirants or lipsticks. Said ester-functional polyorganosiloxanes of formula (I) are very particularly advantageous for the formulation of oily media used in the composition of sun gels, deodorants, or make-up products. Said oily media then contain more than 10%, preferably more than 50% of their weight of volatile silicone oils, media which can optionally be thickened in order to form translucent gels by using, for example, alkyl grafted silicone waxes such as MIRASIL WAX B from Rhône-Poulenc (behenic ester dimethicone).

Deodorant or antiperspirant-fighting compositions ("antiperspirants") are described in the literature. Such compositions generally contain silicones due to the sensory properties provided by them. The volatile nature of cyclic silicones results in an absence of feeling of cold after deposition on the skin, a non-greasy, non-sticky feel and excellent lubricating behavior. These highly appreciable properties for giving a cosmetically acceptable character to the compositions are transferred to the others constituents of these compositions such as the active constituents associated with silicones. These compositions may also contain other types of silicone such as those known under the names dimethicone copolyol, diphenyl dimethicone, phenyl dimethicone, amodimethicone ... (CTFA dictionary). Many other components are found in deodorant or "antiperspirant" compositions, either active against perspiration or the formation of unpleasant odors, or modifying the physical appearance of the compositions, depending on whether the final composition is in the form of a liquid, gel or solidified medium. Depending on their physical appearance and depending on the degree of gelation chosen, these compositions can be in the form of sticks, extruded gels, ball applicators, creams, etc.

The application to the skin of the gel, of thick or gelled cream or of the solidified medium is made more pleasant when the melting or softening temperature of the gel is close to the temperature of the skin, which results in an effect of slip during application.

Common thickening, gelling or solidifying agents are the lithium, sodium, potassium, aluminum, zirconium, cerium ... salts, stearic, hydroxystearic, behenic, montanic acids, esters of carboxylic or hydroxycarboxylic acids in C14-C30 and glycol, polyglycol, glycerol, polyglycerol, C ₂ -C ₃₀ aliphatic alcohols, C14-C30 ethers of polyethylene glycol or polypropylene glycol, 0-14-030 aliphatic alcohols, alkyl grafted silicone waxes and in particular waxes behenic ester dimethicone type ... There are also among the texturing agents, conventional waxes having melting points between 30 ° C and 150 ° C such as beeswax, spermaceti, camauba wax, paraffin , microcrystalline waxes, ceresin, ozokerite.

The deodorant or antiperspirant compositions also contain hydroxylated compounds such as ethanol, propylene glycol, glycerol.

While volatile silicones are generally compatible with alcohols, the same does not apply to non-volatile silicones, the presence of which is desirable for providing emollience, water resistance, anti-transfer or afterglow. If certain non-volatile silicones, such as for example dimethicone copolyols, can be introduced in a limited quantity into media containing high proportions of alcohols, their negative contribution to the sensory profile of the composition makes their use very limited. Said polyorganosiloxanes having an ester function of formula (I) are particularly advantageous because they have the property of being compatible with media rich in alcohols, without harming the sensory profile of the formulation. In addition, the polyorganosiloxanes having an ester function of formula (I) improve the cosmetic feel of the composition by providing a feel comparable to that of a mineral oil while benefiting from the specific properties of silicones, such as improving the spreading over the skin or non-comedogenicity. Found among the active agents used in the deodorant and / or antiperspirant compositions, astringent agents limiting perspiration, antibacterial agents, absorbent compounds, additives controlling unpleasant odors such as bis (pyridine) -2-2 ' disulfide described in EP-A-483428 or the amino acids described in WO 91/11998 or also undecylenic acid. Among the astringent compounds, there are organic or inorganic salts of aluminum, zirconium, zinc or their mixed salts or their mixtures. These compounds are described or cited in the literature, in particular in the journal Cosmetics & Toiletries, April 1990, pages 35 to 39. Examples of these compounds are aluminum chloride, aluminum and / or zirconium hydrochloride, dihydrochloride aluminum and / or zirconium, aluminum and / or zirconium trihydrochloride, aluminum and / or zirconium tetrachlorhydrate, aluminum and / or zirconium pentachlorhydrate, aluminum sesquichlorhydrate and / or zirconium, aluminum chlorhydrex, aluminum-zirconium chlorhydrex glycine, aluminum and zirconium octachlorhydrate, aluminum sulfate, zinc sulfate, zirconium and aluminum chlorohydroglycinate, Zirconium hydroxychloride, aluminum and zirconium lactate, aluminum and potassium sulphate, aluminum and sodium chlorohydroxylactate, aluminum bromohydrate, zinc sulfocarbonate, aluminum bromide, zinc phenolsulfonate associated with u alminium sulfate. All these astringent compounds can also be encapsulated or protected by film-coating, adsorption, complexation with polymers or by any other suitable technique such as those described in US-A-4624062.

Bactericidal or bacteriostatic compounds can also be added to these deodorant compositions in order to control the proliferation of the microbial flora developing on the body. Among these compounds, mention may be made of chlorhexidine and its derivatives, nisin, trichlosan, trichlorocarban.

The persistence of these compounds on the skin can be improved, if desired, by adding from 0 to 10% by weight of polymers such as polydimethylsiloxanes and high viscosity polydimethyldiphenylsiloxanes, preferably greater than 100,000 mPa.s.

The astringent compounds are generally present at concentrations of 1% to 70% by weight, preferably from 5 to 50% by weight. The compounds controlling the proliferation of the bacterial flora on the skin can be introduced in concentrations of 0.1 to 10%.

In addition to all these compounds, other volatile compounds such as ethanol, isopropanol, and emollients such as those described in the journal Cosmetics & Toiletries, July 1992, Nj 107, pages 93 et seq. compounds such as alkylmonoglycerides, alkyldiglycerides, diols such as 1-2-propane diol, 1-3, butane diol, polyethylene glycols or polypropylene glycols and their C ₂ -C esters | ₂ , liquid fatty esters such as isopropyl palmitate, ethyl-2-hexyl cocoate, myristyl myristate, C ₂ - C-JO esters of isostearic acids or C -Cg hydroxycarboxylic acids, non-volatile silicones such as linear polyalkylsiloxanes, copolyol silicones or copolyethers ..., perfumes, humectants such as glycerol, sorbitol, urea, collagen, aloe vera, hyaluronic acid, alkoxylated sugar derivatives or their esters such as GLUCAM P20® or GLUCAM E20® sold by AMERCHOL, water. When the composition contains agents of marked hydrophilic nature, compatibilizing agents such as anionic, nonionic, cationic or zwitterionic surfactants can be used. Among these surfactants, those comprising a polyorganosiloxane skeleton are preferred.

Said ester-functional polyorganosiloxanes of formula (I) can be used as anti-transfer agents in cosmetic sunscreen compositions. Other silicones may be present.

Cyclic volatile silicones, such as octamethyl cyclotetrasiloxane, are used for their volatility which allows rapid drying of the composition applied to the skin without resulting in a feeling of cold. In addition, they provide the compositions with the desired cosmetic properties by facilitating the spreading of the compositions on the skin and by reducing the oily or oily nature of these compositions, particularly when they are formulated in the form of oil, sun gel or oily continuous phase emulsion. In general, silicones are also used for their good emollient or protective properties for the skin. These properties are described for example in a monograph of PUS Food and Drug Administration (Department of Health and Human Services, Food and Drug Administration, Skin Protectant Drug Products for Over the Counter Human Use, 21 CFR Part 347). The silicones best suited for their emollient properties are polydimethylsiloxanes, silicone copolyols, diphenyidimethicones, phenyltrimethicones, alkylpolysiloxanes, dimethiconols, with viscosities of between 20 and 10,000 mPa.s.

Water resistance is essential to ensure the persistence over time of sun protection or UV protection on the skin. The use of high molecular weight polydimethylsiloxane to ensure better persistence on the skin of anti UV active agents is taught in EP-A-197485. In particular, polydimethylsiloxane with a degree of polymerization greater than 5000 dimethylsiloxy units are substantially resistant to washing. However, optimizing the sensory profile often involves the use of other compounds than silicones, in particular if the dry appearance needs to be modified. To meet the expectations of consumers who demand more and more "oil-free" products, it becomes necessary to develop alternative solutions to mineral oils, in particular non-occlusive products. Mineral oils have this unwanted occlusiveness property.

In addition to these additives, the cosmetic compositions protecting against the effects of UV radiation contain organic molecules acting as UV filters, or mineral particles acting as a physical barrier to UV radiation. These UV filters or adsorbents are well known in the literature; they are for example described in the article in the journal Cosmetics & Toiletries, Vol 102, March 1987, p21 and following. Mention may be made, for example, of UV filters such as para amino benzoates and their derivatives, salicylates, cinnamates, benzophenones, benzylidene camphor, benzotriazoles and their derivatives and in general the filters cited in Annex 7 to European directive 76/768 / EEC. These UV filters can also be grafted onto a polymer chain, in particular onto a polysiloxane chain.

Among the mineral particles, there may be mentioned particles of titanium oxide, zinc oxide or cerium. These mineral oxide particles or nanoparticles are optionally covered on the surface with polymers, organic molecules or other mineral compounds in order to improve their compatibility with the organic phases and reduce their surface reactivity such as photocatalysis. Said ester-functional polyorganosiloxanes of formula (I) can be introduced into the sun protection compositions at concentrations of between 0.5% and 90% by weight of the composition, preferably from 5% to 20% by weight of this composition, in order to improve the feel of these compositions, to facilitate their spreading, to convey ingredients making it possible to increase the persistence of active agents such as anti UV on the skin and to maintain over time the protective activity of the composition deposited on the skin. Said ester-functional polyorganosiloxanes of formula (I) can be combined with gelling or thickening compounds such as the waxes or waxy media described above.

In addition to these compounds, the sun protection compositions may include the emollients conventionally used in cosmetics, perfumes, dyes, pigments or lacquers, preservatives, active compounds against oxidation - or free radicals, skin moisturizers and water.

Said ester-functional polyorganosiloxanes of formula (I) can also be used in cosmetic make-up compositions to give them an anti-transfer property.

Anti-transfer effect makeup compositions may also contain volatile, low viscosity solvents such as isoparaffins containing 8 to 20 carbon atoms, or mixtures thereof, as well as non-volatile silicones such as cyclic or linear polydimethylsiloxanes. These makeup compositions can also contain silicone waxes, the melting point of which is at least greater than 25 ° C. The function of these waxes consists in gelling the organic phase of the composition. As examples of suitable silicone waxes, mention may be made of lauroyl trimethylolpropane siioxy silicate, risostearyltrimethylolpropane siioxy silicate, alkyl C -C3Q polydimethylsiloxanes, silicone waxes with ester function such as behenic ester dimethicone marketed by the company Rhône-Poulenc.

The makeup compositions can also contain other waxes whose melting point is generally of the order of 35 to 120 ° C. such as synthetic waxes, ceresin, paraffins, okozerite, carnauba wax, candelilla wax, cocoa butter, or a mixture thereof. The makeup compositions may also contain powders or more generally dry materials, the particle size of which is generally between 0.02 and 50 microns. These powders can be colored or not (white powder). By way of example, there may be mentioned bismuth oxychloride, mica and mica titanium, optionally functionalized silica, synthetic polymers such as Teflon, polyacrylates, polyethylenes or nylon, alumina silicate, bentonites , cellulose, magnesium derivatives such as aluminosilicate, oxide, carbonate, hydroxide, montmorillonites, talc, zinc stearate, titanium oxide, cerium oxide, or mixtures thereof . These various products may have been modified at the surface with mineral oils or silicone oils in order to improve their compatibility in hydrophobic medium.

You can also find organic or mineral pigments. The organic pigments are generally of aromatic nature such as azo, indigoid, triphenylmethane, anthraquinone, and xanthine and are included under the names D&C and FD&C. Inorganic pigments are generally insoluble metal salts of coloring additives.

Generally, the pigment / powder weight ratio is between 1/20 and 20/1 depending on the type of makeup formulation. Depending on the type of formulation, the amount of pigment will generally vary between 5 and 50% of the total composition cosmetic. Likewise, the quantity of powder may vary from approximately 10 to 20% of the weight of the composition.

The makeup composition may also contain oils, preferably mixtures of oils of different viscosity. Oils with a viscosity between 5 and 100 mPa.s can be used at 25 ° C. For example, oils such as isotridecyl isonononoate, cetyl stearate, Pisodecyl neopentanoate, coco dicaprylate / caprate, isododecanol, or mixtures thereof, may be used. It is also possible to use oils with a viscosity of between 200 and 1,000,000 mPa.s at 25 ° C. such as, for example, castor oil, lanolin derivatives, coconut oil, triglycerides, rapeseed oil, trihydroxystearin, wheat cream oil, cholesterol, or mixtures thereof. These oils can generally constitute from 1-20% of the total of the makeup formulation.

It is also possible to use other ingredients such as preservatives, antioxidants, active agents conventionally used such as vitamins or their derivatives.

The following examples are given by way of illustration.

Example 1

Hydrosilylation

Into a 5000 I reactor under nitrogen equipped with a double-jacket cooling device and a condenser, 1360 kg of allyl alcohol (i.e. approximately 23,448 moles) are introduced at ambient temperature (20-25 ° C.) and 232 g of Karstedt catalyst, Pt "0" complex in divinyltetramethylsiloxane containing 10% platinum. The reaction mass is brought to reflux of the allyl alcohol 0 ~ eb = 97 ° C.) and 2,086 kg (ie 9,676 moles of SiH units) of an oil of the following formula are introduced over 3 hours:

Me ₃ SiO (SiMe O). ₉ (SiMeHO) - ₄ SiMe ₃

The reaction is allowed to continue at 103 ° C for 4 h 30 min. The content of SiH units

.3 dosed by gasometry is less than 7.10 mole / Kg.

The volatiles are removed at atmospheric pressure for 1 hour at a temperature of 120 ° C. and then for 3 hours at a temperature of 120 ° C. under 20 mbar. Next, residual volatiles are entrained with nitrogen (2 h, 120 ° C., 40 mbar).

3642 Kg of a cloudy oil are collected. NMR and IR analyzes (v C≈O: 1745 cm ^" ) confirm the general structure of the product obtained:

Me ₃ SiO (SiMe O) _ ₉ (SiMe [CH ₂ CH2CH ₂ OH] O) -4 SiMe ₃

The number of moles of α-ethylenic units or impurities (-Si-O-allyl, free allyl alcohol) is of the order of 0.06 mole / Kg.

Esterification

3888 g (or approximately 12 moles of -OH units) of the above-prepared γ-hydroxypropylated oil are introduced into a 5000 ml reactor under nitrogen equipped with a double-jacket cooling device.

825 g (ie 10.5 moles) of acetyl chloride are introduced over 2 hours while maintaining the temperature of the reaction mass between 17 and 23 ° C.

A strong release of hydrochloric acid is observed which is eliminated by means of a stream of nitrogen. At the end of the addition, the hydrochloric acid content is 3.2% by weight. The elimination continues at room temperature (22-25 ° C) for 8 hours so as to obtain a content of 1.56% by weight. 330 g of sodium hydrogen carbonate (ie 3.9 moles) are then added and the mixture is left to react for 39 hours at room temperature (22-25 ° C.) so as to remove all the hydrochloric acid. The volatiles are removed under reduced pressure for 9 hours at 10 mbar at 100 ° C. It is then filtered on cardboard (quality 616) and 3479.4 g of a clear oil of dynamic viscosity at 25 ° C. of 44 mPa.s are collected.

NMR and IR analyzes (v C≈O: 1745 cm) confirm the general structure of the product obtained:

Me ₃ SiO (SiMe ₂ O) _ ₉ (SiMefC ^ C ^ C ^ OCOCH ^ O) ^ SiMe ₃ The number of moles of α-ethylenic units or impurities (Si-O-allyles, free allyl alcohol, allyl acetate ) is around 10 mole / Kg.
