Technical Field

The present invention relates to a makeup cosmetic composition and a method for producing the same, and more particularly, to a makeup cosmetic composition comprising a component (a) composed of a partially crosslinked organopolysiloxane polymer containing a long-chain alkyl group, a component (B) composed of a partially crosslinked organopolysiloxane polymer other than the component (a), a component (C) composed of a silicone oil, a component (D) composed of one or more liquid oils selected from hydrocarbon oils and/or ester oils, and a component (E) composed of a powder, and a method for producing the same.

Background

Since cosmetics such as color cosmetics are applied directly to the face, nails, etc., the use thereof is pleasantly performed, the use thereof is perfectly finished, and the use feeling of makeup is beautiful, and the use effect is very important, which determines the value of the cosmetics. The first step in applying the cosmetic is to first tilt the bottle to allow the contents to flow into the palm of the hand, dig out the container with the fingertips, pour out the contents from a metal or plastic tube, and the second step is to paint, thinly spread out and rub on the skin surface. In such a process, the fluidity of the cosmetic is changed, and the feeling of the skin is also changed due to the evaporation of oil and water absorbed by the skin during the use of the cosmetic from the beginning to the end. Therefore, the physical properties are complicated. The evaluation of the cosmetic is expressed by words of hard, soft, tender, stretched, wrinkled, sticky, rough, powdery, and the like. These manifestations are the sensory response from the beginning of the application of the cosmetic to the end of its use.

The cosmetic is classified according to the flow characteristics, feeling of use, and the like of the cosmetic in the stage of use. First, the appearance, the properties when the cosmetic to be used is touched, the ease of taking out the cosmetic from the container, and the like are evaluated before use. The properties of the cosmetic in contact were evaluated by the force with which the thumb or forefinger pressed the cosmetic. The ease of taking out the cosmetic from the container was evaluated based on the flow resistance and the deformation state of the cosmetic when the cosmetic was taken out from the container. Next, the adhesiveness at the site of use, the ease of spreading the sample on the skin, and the feeling of penetration through the skin were used as evaluations during use. The stretchability and the permeability were also evaluated perceptually. More specifically, the evaluation after use is made by the skin appearance of the part to be used, the ease of wiping off the remaining cosmetic, and the like, depending on the touch, the vision, and the like after the cosmetic is applied or applied at regular intervals. It has been reported that in order to accurately evaluate the flow characteristics, feel in use, and effect of use of cosmetics, it is necessary to use a rheological technique (for example, see non-patent document 1).

According to Newton's law, a liquid in a flow state is called Newtonian fluid, and the flow behavior of the liquid is called Newtonian flow; on the other hand, a liquid in a flow state not according to newtonian rules is called a non-newtonian fluid, and its flow behavior is called a non-newtonian flow. Most emulsions, suspensions, polymer solutions, semi-solid materials, etc. are suitable for use in non-newtonian fluids. The faster flow regime, which is not proportional to the applied shear stress, is called pseudoplastic flow; a flow form that is difficult to flow without a certain proportion to the applied shear stress is called a dilatant flow (see, for example, non-patent document 2).

Recently, as a suitable material having a swellable composition, which is one of the above-mentioned flowable forms, as a cosmetic composition such as a moisturizer, a massage agent and the like, there has been developed a swellable composition comprising the following components (a), (B) and (C), that is, a swellable composition containing (a) polyethylene oxide having a weight average molecular weight of 10 ten thousand or more, (B) a water-swellable clay mineral and (C) water (for example, see patent document 1); or a swellable composition having the same characteristics, which comprises (a) an O/W emulsion containing a ceramide-like or fatty acid having an average oil droplet diameter of 0.2 μm or less and (B) a water-soluble polymer having an average molecular weight of 30 ten thousand or more (see, for example, patent document 2).

On the other hand, various rheological improvement strategies have been tried on makeup cosmetics. For example, oily solid cosmetics are combined with a large amount of oil and thus appear greasy and sticky, and cosmetics using silicone oil have been developed in order to overcome poor spreadability, spreading properties and strong oily film feel. Because of the excellent properties of silicone oils, various silicone oils have been used, and are widely used as oily components useful in cosmetics. This is because silicone oils have good characteristics and conditions of low tackiness, smoothness, good stretching, refreshing touch feeling, and further rich in lubricity and hydrophobicity, and being odorless. Such silicone oil is represented by chain dimethylpolysiloxanes having different molecular weights and viscosities, and cyclic octamethylcyclotetrasiloxane and tolylpolysiloxane can be cited.

In order to improve the silicone oil and to obtain a safe cosmetic having a smooth and refreshing feeling in use, a feeling in use, and a good long-term stability, there has been developed a silicone gel composition which is insoluble in benzene but may contain benzene in an amount equal to or more than the weight of the gel composition itself and R is a substituent₂SiO Unit and RSiO_1.5A silicon polymer having a three-dimensional cross-linked structure with a unit ratio of 1-30: 1,a silicone oil having a low viscosity of 50cs or less, and the weight ratio of the silicone polymer to the low viscosity silicone oil is 5: 95 to 30: 70 (see, for example, patent document 3); in addition, there has been developed an oily solid cosmetic composition which does not cause wrinkles or a lowering of melt-filling property of a cosmetic film, can remove gloss of the cosmetic film, and has a cushion texture; which is suitable for oily solid cosmetics, is composed of components (A) to (D), that is, containing (A) 0.5 to 10% by weight of a partially crosslinked organopolysiloxane polymer, (B) 5 to 50% by weight of a low viscosity silicone oil, (C) 10 to 50% by weight of a spherical powder, (D) 1 to 50% by weight of a solid oil and/or a semisolid oil (for example, see patent document 4).

In addition, in the powder cosmetic, in order to have good adhesion and smooth spreadability, and to improve the uniformity and stability over time of a film, a powder cosmetic containing components (a) to (e), that is, a partially crosslinked organopolysiloxane containing component (a), a liquid silicone oil containing component (b), a liquid oil containing component (c) other than component (b), and a powder containing component (e) is known (for example, see patent document 5); also known is a powdery cosmetic composition containing at least one particle phase and at least one fatty phase, which further contains at least one gelling agent of a silicone elastomer type having surface-active properties, and in which the particle phase is 50 to 98% by weight relative to the total amount of the composition (for example, see patent document 6).

Further, a composition composed of a crosslinked organopolysiloxane polymer and an oil agent other than silicone oil, and a cosmetic containing the composition are known (for example, see patent document 7).

Further, it is preferable that a solvent such as silicone oil is added to the composition containing the above components, and the composition is compression-molded while absorbing the solvent; further preferred is a product filled into a dish-like container after compression molding. The dish-like container can be packed in a compact container, and a plurality of the dish-like containers can be packed in one compact container to be packaged. The term "dish-like container" as used herein means a thin and small-sized dish-like container made of metal or synthetic resin that can be accommodated in a compact container. According to the present invention, the oil-based cosmetic is a product in which powder is dispersed in an oil base, and is different from a powder solid cosmetic, an aqueous gel cosmetic, and an emulsion cosmetic. The makeup cosmetics include eye shadow, foundation, concealer, floor powder, blush, lipstick, mascara, eyeliner, eyebrow pencil, etc.

The partially crosslinked organopolysiloxane polymer containing a long-chain alkyl group as the component (a) is not particularly limited as long as it is a compound containing a long-chain alkyl group on a silicone rubber partially exhibiting a three-dimensional structure having a crosslinking bond; the above-mentioned long-chain alkyl group may preferably be a straight-chain alkyl group having 8 to 30 carbon atoms in number. The component (A) is obtained by addition polymerization of an organohydrogendiene polysiloxane with an organopolysiloxane; the organohydridodiene polysiloxane is prepared from a compound selected from, for example, SiO₂Unit, HSiO_1.5Cell, RSiO_1.5Unit, RHSiO unit, R₂SiO Unit, R₃SiO_0.5Unit and R₂HSiO_0.5At least one structural unit of a unit (wherein R is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms excluding aliphatic unsaturated groups), the number of hydrogen atoms bonded to silicon atoms contained in the molecule being 1.5 or more on average; the organopolysiloxane is selected from SiO₂Unit, (CH)₂＝CH)SiO_1.5Cell, RSiO_1.5Unit, R (CH)₂CH) SiO Unit, R₂SiO Unit, R₃SiO_0.5Unit and R₂(CH₂CH)SiO_0.5A unit (wherein R is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms excluding aliphatic unsaturated groups) and contains an average of 1.5 or more vinyl groups bonded to silicon atoms in the molecule.

Examples of such a partially crosslinked organopolysiloxane containing a long-chain alkyl group include (vinyldimethicone/lauryl dimethicone) crosslinked polymers under the INCI name (International Nomenclature Cosmetic Ingredient labeling names). Commercially available products include silicone gels in which a hydrocarbon oil or ester oil is blended with a partially crosslinked organopolysiloxane polymer containing a long-chain alkyl group. Specific examples thereof include KSG-41 containing 65 to 75% by mass (hereinafter abbreviated as "%") of mineral oil; KSG-42 containing 70-80% isododecane; KSG-43 containing 65-75% of trioctane (glycerol tri-2-ethylhexanoate); KSG-44 (all manufactured by shin-Etsu chemical industries, Ltd.) containing squalane 65 to 75%, and the like.

One or two or more components (a) of the present invention may be used according to purposes, and although the content thereof is not particularly limited, the content is preferably 0.001 to 15%, particularly preferably 0.1 to 10% in the cosmetic. After the component (A) is mixed, the general compatibility of the oil can be improved, and the oil and the powder can be uniformly mixed. Furthermore, silicone oils having poor adhesion to the skin can be used in combination with oils having high adhesion to the skin.

The partially crosslinked organopolysiloxane polymer other than component (A) of component (B) is not particularly limited as long as it is a silicone elastomer exhibiting a three-dimensional structure having a partially crosslinked bond, and examples thereof include polymers obtained by crosslinking and bonding organopolysiloxanes, partially containing a three-dimensional crosslinked structure, and consisting of R₂SiO Unit and RSiO_1.5Unit composition, may also contain R₃SiO_0.5Unit and/or SiO₂A compound of a unit (however, R in each constituent unit may be, for example, a hydrogen atom;alkyl groups such as methyl, ethyl, and propyl; aryl groups such as phenyl and tolyl, and aliphatic unsaturated groups such as vinyl; the substituents of the fluoro group, the oxirane group and the like may be the same or different ones), and more specifically, polymers described in JP-B-8-6035 and JP-A-2001-342255 are mentioned.

Examples of the component (B) include a (dimethicone/vinyl dimethicone) crosslinked polymer having the INCI name (International Nofunctional Cosmetic Ingredient labeling names). Further, although the component (B) may be a homopolymer, it is usually used in a mixture with a low-viscosity silicone oil in a large amount. Specific examples of such mixtures include KSG-15 (partially crosslinked methylpolysiloxane 5 parts and decamethylcyclopentasiloxane 95 parts), KSG-16 (partially crosslinked methylpolysiloxane 20-30 parts and methylpolysiloxane 70-80 parts), KSG-17 (partially crosslinked methylpolysiloxane 5 parts and octamethylcyclotetramethylsiloxane 95 parts), KSG-18 (partially crosslinked methylpolysiloxane 10-20 parts and methylphenylpolysiloxane 80-90 parts) (all manufactured by shin-Etsu chemical industries).

One or two or more components (B) may be used depending on the purpose, and the content thereof is not particularly limited, but is preferably 1 to 20%, particularly preferably 5 to 15% in the cosmetic. The elasticity of the cosmetic can be maintained by blending the component (B), and the structure of compression molding in a dish-shaped container can be maintained.

The silicone oil as the component (C) may be either linear or cyclic, and has a viscosity of 50cs or less, for example; for the purpose of non-stickiness and a refreshing feeling (feeling) in use, and for the purpose of making a composition before compression molding in the production process of a color cosmetic into a paste-like excellent solvent, a silicone oil having a low viscosity of 30cs or less is preferable. Examples of low-viscosity silicone oils include: the linear dimethylpolysiloxane (dimethicone), tolylpolysiloxane, dimethylpolysiloxane-tolylsiloxane copolymer, and cyclic octamethylcyclotetramethylsiloxane and decamethylcyclopentasiloxane of the oligomer skin, and specific examples thereof include those having the INCI name dimethicone (シリコン KF-96(6CS), シリコン KF-96(10CS), シリコン KF-96(20CS) manufactured by shin-Etsu chemical industries, Ltd.), and one or two or more of them are used in combination according to the purpose. The form of the silicone oil blended may be a form in which the silicone oil is blended with a partially crosslinked organopolysiloxane polymer other than the component (a) as the component (B) and used as a gel-like polysiloxane such as KSG-16, or a form in which the silicone oil is used alone, and these forms are preferably used in combination. Further, as the silicone oil as the solvent, a low polymerization degree linear dimethylpolysiloxane as a silicone oil of low viscosity is preferable, and more specifically シリコン KF-96(6CS), シリコン KF-96(10CS), シリコン KF-96(20CS) are preferable in this order.

The content of the silicone oil as the component (C) in the cosmetic is 30-70%, preferably 40-60%. When the amount is 30% or more, a particularly good feeling of freshness in use can be ensured, and when the amount is 70% or less, makeup can be particularly maintained, and the possibility of the impact resistance of the molded product being impaired even when the molded product is compression molded in a dish-like container can be reduced. In the preparation process of the color cosmetic, although the silicone oil such as dimethicone added as a solvent to the composition before compression molding can be absorbed during compression molding, part of the silicone oil as the component (C) added may be absorbed.

The liquid oil selected from hydrocarbon oils and/or ester oils as component (D) is preferably a liquid material at 25 ℃, and examples thereof include liquid paraffin, heavy liquid isoparaffin, squalane, polybutene, polyisobutylene, etc., as hydrocarbon oils, and examples thereof include glyceryl tri-2-ethylhexanoate, 2-ethylhexyl p-methoxycinnamate, cetyl isooctanoate, isopropyl myristate, isopropyl palmitate, octyl laurate myristate, glyceryl trioctanoate, polyglyceryl diisostearate, diglyceryl isostearate, diisostearyl malate, neopentyl glycol dicaprylate, jojoba oil, etc., and one or more kinds thereof may be used.

By blending component (D), skin affinity, a feeling of adhesion, and the like can be imparted during use. Although the content of the component (D) is not particularly limited, it is preferably 0.5 to 10%, more preferably 1 to 8% in the cosmetic composition, from the viewpoint of absorbing more of the solvent such as silicone oil used in filling. The form of the component (D) may be, for example, a form in which it is used in combination with a partially crosslinked organopolysiloxane polymer containing a long-chain alkyl group as the component (A) as in KSG-43 or a form in which it is used alone.

The powder as the component (E) is not particularly limited as long as it is a powder commonly used in cosmetics, but is preferably contained in an amount of 30 to 70% in the cosmetics. The powder of component (E) is preferably a powder containing plate-like particles, and more preferably a powder containing plate-like particles having luster such as pearl luster. Further, spherical powder is more preferably contained. The chemical product may contain 10 to 50% of plate-like powder, preferably 20 to 40%, more preferably 30%. Furthermore, it is preferable to blend a glossy plate-like powder in a ratio of 30 to 98% in the powder, and if the amount is within this range, a less coarse deposit is formed and a good feeling is obtained when the powder is applied to the skin. In addition, 1 to 10% of spherical powder, preferably 1 to 5%, may be blended in the cosmetic, and 0.01 to 30% of spherical powder, more preferably 0.5 to 10%, may be blended in the powder. The spherical powder has powdery feeling, good extensibility and extensibility, and good non-sticky and refreshing feeling. Further, since the system is made uniform and has an effect of making it difficult to remove the cosmetic from the applicator such as fingers, small pieces, sponge, brush, etc., it is preferable to use a powder which is not uniform and is well disintegrated in a system having an opposite effect in combination to adjust the difficulty of removing the cosmetic from the fingers. The spherical powder and the well-disintegrated powder are properly combined and mixed in the range of 0.001: 99.99-90: 10, so that the cosmetic can be easily adjusted to be taken out from the finger.

Further, the value of elasticity (L2/L1) in the TPA (test profile analysis) measurement of the color cosmetic of the present invention by a texture analyzer is preferably 0.48 to 0.99, more preferably 0.50 to 0.99, and a cosmetic rich in elasticity can be obtained within this value range. Further, the elastic value (L2/L1) in the TPA measurement by the texture analyzer in the present invention means that a color cosmetic was filled into a mold having a thickness of 4mm as a sample, and a "texture analyzer" manufactured by the K.K. of Tenn-Chiense Co., Ltd was used as a measuring instrument, and the TPA measurement condition was a cylindrical probe having a diameter of 2mm and a probe speed of 0.5mm/sec, the deformation amount was adjusted to 25% without completely damaging the sample (non-damaged region), the sample was subjected to the above-described probe with 2 times of force application, the time difference between the first and second time was maintained for 3sec, the height change due to the first deformation was designated as L1, the height change due to the second deformation was designated as L2, and the value obtained by evaluation was designated as L2/L1, which indicates the return ratio of the deformation due to the external force when the external force was removed (see "dictionary for food physical Properties" (Yangxiangtze Tang) of the sambucian-Miyao, Linhongtong, Chuanchi).

The method for producing a color cosmetic of the present invention is not particularly limited as long as the composition containing the above-mentioned component (a), component (B), component (C), component (D) and component (E) is dispersed in a solvent, and the mixture is filled into a container and then compression-molded while absorbing the solvent, but the amount of the solvent to be added is preferably 30 to 100 parts by weight, more preferably 40 to 90 parts by weight, and still more preferably 45 to 60 parts by weight, based on 100 parts by weight of the cosmetic, because the viscosity can be reduced at the above-mentioned ratio, and the filling can be easily performed, and a uniform cosmetic can be obtained. The solvent may be any solvent capable of being absorbed by the composition containing components (a) to (E) dispersed therein and then filled into a container, and any of silicone oil, hydrocarbon oil, and ester oil may be used, but silicone oil is preferable, and linear dimethylpolysiloxane (dimethicone) having a low degree of polymerization is more preferable. More specifically, the powder of the component (E) is uniformly dispersed in a henschel mixer (manufactured by mitsui corporation), and after the partially crosslinked organopolysiloxane polymer containing a long chain alkyl group as the component (a) and the partially crosslinked organopolysiloxane polymer other than the component (a) as the component (B) are pre-dispersed by a disperser, the silicone oil as the component (C) and the liquid oil as the component (D) selected from hydrocarbon oils and ester oils are added to the dispersion and mixed uniformly, and the uniformly dispersed component (E) is stirred by the henschel mixer (manufactured by mitsui corporation), and the components (a) to (D) are added thereto, and the silicone oil as a solvent such as dimethyl silicone oil is added and mixed uniformly into a slurry. The paste-like composition is filled into a metal dish-like container, and the metal dish-like container is compression-molded while absorbing the added solvent, thereby obtaining a makeup cosmetic. Further, the filled metal dish-shaped container can be packed in a small container.

The present invention will be described more specifically with reference to the following examples, but the scope of the present invention is not limited to these examples.

[ Synthesis of partially crosslinked organopolysiloxane Polymer containing Long-chain alkyl groups ]

(measurement of Pin load value)

A color cosmetic was filled in a 4mm thick mold as a sample, and a pin load value was measured by using an adapter 3mm phi, an entry distance 1.5mm, and a rising speed 2cm/min as hardness measurement conditions using a measuring machine "RHEO TECH FUDOH RHEO METER" manufactured by レオテツク.

As can be seen from table 1, the eye shadow of examples 1 to 9, which are products of the present invention, are excellent in all items of "taking-out property of fingers", "elasticity at the time of use", "refreshing feeling of use without stickiness", "skin adhesion", "cosmetic durability such as water resistance and sebum resistance", and "impact resistance". Particularly, in terms of "elasticity during use" and "feeling of use without stickiness", as will be described later with reference to fig. 1, the feeling of elasticity is very good at first, but as the feeling of elasticity disappears, it spreads slowly, and the feeling of touch to the human body becomes a powdery texture. In contrast, comparative example 1 in which the silicone polymer (I) of component (a) was not blended had poor "skin adhesion" and "cosmetic durability such as water resistance and sebum resistance"; in addition, comparative example 2 in which the silicone polymer (II) containing no component (B) was blended was inferior in "elasticity at the time of use", "cosmetic durability such as water resistance and sebum resistance", and "impact resistance"; and comparative example 3, which does not contain component (D), is a product with poor "skin adhesion".

(measurement of dynamic viscoelasticity)

The makeup cosmetic of the present invention is characterized by having a unique touch and elasticity, unlike conventional oily eye shadows and powdery solid eye shadows. Therefore, the dynamic viscoelasticity of the eye shadow described in example 1 was measured by using an フル - ド spectrometer (RES-II, レオトリツク). The geometrical characteristics were determined using a 25-50mm parallel plate or クエツト, mainly using the mode of measurement of the deformation amplitude dependence (dynamic frequency sweep). The deformation here was carried out at a frequency of 1Hz with the amplitude of deformation of 10 at 100% when the parallel plates were moved with an amplitude of deformation equal to the spacing between the plates^-8To 10³To change between. The storage elastic modulus (G') and the loss elastic modulus (G ") were obtained by measurement under these conditions. Thus, FIG. 1 shows the curves of G '(storage elastic modulus: elastic term) and G' (loss elastic modulus: viscosity term) measured using the cosmetic of the invention (eye shadow of example 1). G' on the vertical axis represents storage elastic modulus (elastic term), G ″ represents loss elastic modulus (viscous term), and the horizontal axis (%) represents deformation. In fig. 1, since the elastic term is significantly reduced after increasing the portion, but the viscous term is not increased but is reduced slightly less than the elastic term, the elastic term is very good at first, and the feeling of spreading slowly to the human body becomes a powdery texture as the elastic term disappears.

(measurement of TPA)

Tpa (texture profile analysis) was measured on the powder eye shadow and the emulsion eye shadow (oily eye shadow) of the products of the present invention (examples 1, 6, and 10), the control (comparative example 2), and the conventional products using a texture analyzer manufactured by engineerine research corporation. The measurement conditions were a 2 mm. phi. cylindrical probe, a probe speed of 0.5mm/sec, and a deformation amount was adjusted to 25% without breaking the sample (non-broken region). The TPA measurement was performed by applying 2 times a force to the sample with a fixed probe, maintaining the time difference between the first and second times for 3sec, and taking the height change due to the first deformation as L1, the height change due to the second deformation as L2, and L2/L1 as an index of elasticity (springiness). For example, in the case of a spring, since it is a full elastomer, L1 ═ L2, thereby resulting in an elasticity L2/L1 of 1. Table 2 shows the results for elasticity (L2/L1). It is clear from table 2 that the product of the invention has elasticity. In addition, fig. 2 shows the results of TPA measurement of the product of the present invention (example 1) with a texture analyzer as a reference.
