Definitions
- Emulsifying composition and process for producing a Pickering O / W emulsion composition Emulsifying composition and process for producing a Pickering O / W emulsion composition
- the present invention relates to an emulsifying composition of plant origin ready for use and directly usable cold which finds applications particularly in the field of cosmetics.
- This composition is self-sufficient and directly stabilizes an emulsion without the necessary addition of a co-emulsifier.
- This emulsifying composition makes it possible in particular to easily produce very fine O / W emulsions with various textures, which are very compatible with the skin and furthermore have a dry, fresh, silky and non-greasy feel, even with a high fat content. in the emulsion.
- An emulsion is a dispersion of a liquid (or a material made liquid) in fine droplets in another liquid immiscible with the first. It has a macroscopically homogeneous appearance but appears heterogeneous under the microscope.
- the liquid in the form of droplets is called dispersed phase (or discontinuous), while the other liquid is called dispersant phase (or continuous).
- an emulsion is composed of water and oil and two phases (single emulsion): a hydrophilic phase (aqueous) and a lipophilic phase (fat).
- emulsions most commonly encountered are emulsions comprising a lipophilic phase dispersed in a continuous aqueous phase and are called oil-in-water (O / W) emulsions, as opposed to water-in-oil (W / O) emulsions.
- O / W oil-in-water
- W / O water-in-oil
- EP 0 685 227 proposes a very complex system of antisolar cosmetic compositions, comprising an aqueous continuous phase, a protective system capable of filtering UV rays, a surfactant, and organic solvents (alcohols and lower polyols). and at least one polymer or more particularly a crosslinked copolymer (alkyl acrylates, vinyl acetate).
- Document FR 2 858 777 describes an oil-in-water emulsion containing at least one fatty substance (esters of fatty acids, waxes, butters, natural oils - vegetable, animal, of marine origin), synthetic or mineral, hydrogenated oils and mixtures thereof), at least one surfactant (ethoxylated polyglycerol fatty acid esters, alcohol ethoxylates), at least one co-surfactant and water.

- surfactant ethoxylated polyglycerol fatty acid esters, alcohol ethoxylates
- surfactants in products intended to be applied in humans or animals, whether in topical, oral or other forms, can be problematic. Indeed, surfactants can damage cell membranes. Thus, efforts are made, particularly in the cosmetic field, to reduce the potentially harmful effects of surfactants or eliminate the use of surfactants.
- an object of the present invention is to provide a composition which, in the presence of water, is capable of forming, even in a cold process, a stable emulsion by adding oil or fat. It eliminates the use of conventional surfactants, of petroleum origin and non-biodegradable, including no longer use derivatives of glycols and ethoxylated derivatives. From this point of view, the composition according to the present invention also makes it possible to manufacture Pickering type emulsions. Emulsions of this type are devoid of surfactant and are stabilized by colloidal particles such as usually silicas which are placed at the interfaces of the continuous phase and the dispersed phase.
- these colloidal particles are organic particles consisting of inclusion complexes between at least one cyclodextrin and at least one fatty molecule. These particles are very advantageously compatible with the skin or the hair and do not damage the cellular membranes of animal nature.

- Another object of the present invention is to provide a ready-to-use composition, allowing the formulator a very simple implementation, with a minimum energy input, especially by introducing all the ingredients into the same tank or reactor (formulation called "one pot” in Anglo-Saxon language).
- the composition which is the subject of the present invention is advantageously usable according to a "cold process", that is to say even at ambient temperature, unlike many solid or conventional solid emulsifiers. pastes such as waxes that require a rise in temperature for their implementation (ingredient requiring to be melted and usable "hot”).
- cold process it is meant that the emulsifying composition can be carried out directly by dispersion in water at a water temperature below 45 ° C, better below 35 ° C and more preferably at room temperature.
- Another object of the present invention is to provide a composition for cosmetic use broad spectrum, that is to say, versatile from the point of view of the end products envisaged: from this point of view, the composition according to the invention can be used in products as diverse as lotions, creams, gels, milks ....

- the amount of beta cyclodextrins is set at 2% or 5% by weight of the composition according to the case.
- the 3-polyglyceryl diisostearate is added in sunflower oil or in isopropyl palmitate with magnetic stirring at 40 ° C. to obtain an oily phase.
- the oily phase is then emulsified in the aqueous phase at 40 ° C. with stirring at 1500 rpm for 15 minutes.
- a preservative is added (mixture based on benzyl alcohol and dehydroacetic acid).
- Figure 2 is a photograph of the 6 O / W emulsions obtained according to the formulations given in Table 1.
- compositions For each of these compositions, the viscosity, the size of the drops, the whiteness, the spread, the bold character, and the penetrating character are measured.
- the compositions may be designated indifferently by the terms samples or produced in the following of the present detailed description.
- the viscosity is measured using a Brookfield DV-ll + Pro viscometer.
- a fixed-size mobile (mobile SP2 to SP7 used according to the viscosity levels in accordance with the instructions of the apparatus) is rotated at a speed of 20 rpm in contact with the produced sample.

- the fat character of the compositions is evaluated by examination under the lamp of the product, 1 minute after making 10 rotations of the product on the skin.
- An evaluator panel then evaluates the resistance of the product when the skin on which it has been applied is placed between the thumb and forefinger and a rubbing motion is applied.
- the evaluator panel also takes into account the oily or non-oily appearance of the skin.
- the penetrating character of the product is evaluated by an examination under the lamp of the product two minutes after making 10 rotations of the product on the skin, by sliding over the skin. A panel of evaluators then assesses the amount of product residue recovered.
- the viscosity of the emulsions increases slightly when the concentration of beta-cyclodextrin increases: it goes from 4000 mPas with 2% beta-cyclodextrin to more than 6000 mPas with 5%. Similarly, the viscosity is higher when the thickener used is cellulose instead of xanthan: it goes from 5000 to 8000 mPas.
- the emulsifying compositions according to the invention advantageously make it possible to obtain a very broad range of viscosity, which can make it possible to prepare both milks and viscous creams.
- the size of the drops decreases when the concentration of beta-cyclodextrin increases, it goes from 35 microns with 2% of beta-cyclodextrin to 15 microns with 5%.
- O / W emulsions obtained using the emulsifying compositions according to the invention have excellent sensory properties (grades ranging from 6 to 10 according to the white, spreading, greasy and penetrating criteria).
- the emulsions are less white when the oil used is sunflower oil than when the oil used is isopropyl palmitate: the descriptor is about 8.25 out of 10 in the case of sunflower oil, against 9.25 out of 10 in the case of isopropyl palmitate. However, the whiteness of the sunflower oil remains satisfactory.
- 15 emulsifying compositions according to the invention comprising different percentages of beta cyclodextrin and polyglyceryl-3 diisostearate were used to prepare 15 O / W emulsions according to the conditions given in Example 1 with a fixed amount of 0.7% by weight. of xanthan and a variable amount of sunflower oil. All percentages given are percentages by weight.
- the different formulations made are shown in Table 3 below.
- Viscosity increases significantly as the concentration of beta-cyclodextrin increases from 4000 mPas with 2.5% beta-cyclodextrin to about 6000 mPas with 4.5% beta cyclodextrins. In addition, the viscosity increases significantly when the oil concentration increases, it is 3500 mPas with 17% oil at about 6000 mPas with 35%.
- the concentration of beta-cyclodextrin does not affect the size of the drops when there is 1% of polyglyceryl-3 diisostearate: it remains stable around 25 microns.
- concentration of polyglyceryl-3 diisostearate is increased to 2% by weight, there is a significant decrease in the size of the drops when the concentration of beta-cyclodextrin increases: it goes from about 80 microns with 2 5% beta-cyclodextrin at about 35 microns with 4.5%.
- the emulsion When the concentration of beta-cyclodextrin increases, the emulsion is increasingly white, from 7.5 to 10 with 2.5% beta-cyclodextrin more than 8 out of 10 with 4.5%. In addition, the emulsion is increasingly white when the concentration of sunflower oil decreases from about 8.5 to 10 with 17% by weight of sunflower oil at 7.5 out of 10 with 25% by weight. weight of sunflower oil.
- Plating is significantly better (ie, easier) when the concentration of beta-cyclodextrin decreases and when that of polyglyceryl-3 diisostearate increases. Spreading is also significantly easier when the beta- cyclodextrin concentration decreases and when that of sunflower oil decreases.
- O / W emulsions having a content of polyglyceryl-3 diisostearate greater than or equal to 2% by weight tend to phase out at room temperature.
- O / W emulsions 4, 6 and 15 are particularly stable and have a particularly small drop size after 10 days. These compositions are therefore particularly interesting.
- An emulsifying composition (called emulsifying composition 15) comprising 4.5 parts of beta-cyclodextrin and 1 part of 3-ployglyceryl diisostearate was also used in the form of a premix, that is to say in the form of an emulsifying composition prepared in advance. It makes it possible to obtain, by dispersion at 5.5% in cold water and before addition of sunflower oil, an O / W emulsions having exactly the same characteristics as the emulsion for which the beta-cyclodextrin and the 3-polyglyceryl diisostearate were introduced separately.
- Sorbitol is a particularly interesting alternative and the compositions prepared according to the same procedure but with sorbitol instead of glycerine also showed very satisfactory performance. It is also possible to choose other polyols such as maltitol, mannitol, xylitol or erythritol.
- References 1 to 5 correspond to products entering compositions
- emulsifiers according to the invention and reference T has an ethoxylated and non-biodegradable control product not according to the present invention.
- the characteristics of the emulsions are as follows.
- compositions comprising 4.5 parts of a crystalline betacyclodextrin or 4.5 parts of amorphous beta-cyclodextrin, associated with 1 part of polyglyceryl-3 diisostearate.
