Description

Cosmetic formulation

The present invention relates to cosmetic formulations comprising certain polysiloxane-polyoxyalkylene copolymers.

In particular, the present invention relates to cosmetic formulations useful in skin care and hair care products, characterized in that they comprise non-hydrolyzable block copolymers having linear polysiloxane-polyoxyalkylene blocks as repeat units.

There are many types of skin care products for different purposes such as creasing cream, cold cream, hand cream, powder, lotion, foundation, mascara, eyeshadow, lipstick, nail polish, anti-sunburn cream. They should have a feeling of cleanliness, good feel, good use, make-up preservation, durability and durability, but should be easily removed from the skin when washed with cleaning cosmetics, water and the like. Some of these characteristics are incompatible with each other. Skin protection products having most or all of these properties are preferred.

As main components of such skin care products, liquid paraffin, paraffin wax, aliphatic acid, higher alcohols, animal fats and oils, and vegetable oils, synthetic esters, polyalkylene glycol derivatives, silicone compounds and the like are used. Silicone compounds are noted for their unique properties such as durability, water resistance, skin affinity, moisture retention, glossiness, water repellency, flexibility, water vapor permeability, gas permeability, film formation, filler retention, lubricity, etc. And application of various silicone compounds to skin protection products. Proposed are, for example, dialkylpolysiloxanes (Japanese Patent Laid-Open Publication No. 119036/1979), amino group-containing polysiloxanes (Japanese Patent Laid-Open Publication No. 58605/1982), pendant polysiloxane-polyoxyalkyls Lene copolymers (Japanese Patent Laid-Open Publication No. 131910/1983, 197432/1984), silicone resin (Japanese Patent Laid-Open Publication No. 28518/1987), esterified polysiloxane (Japanese Patent Laid-Open Publication No. 150288/1988 And dimethyl cyclopolysiloxane (Japanese Patent Laid-Open No. 159489/1988).

Polysiloxanes without hydrophilic groups are difficult to dissolve in aqueous solvents and require large amounts of emulsifiers that can impair the transparency of emulsified liquids and can irritate skin and reduce water resistance. Undesirably, the amino group containing polysiloxane turns yellow. Many polyoxyalkylene group pendant dialkylpolysiloxanes have been proposed, but they lack water resistance, retention, skin feel, glossiness, and the like. Silicone resins require the use of low molecular weight cyclosiloxanes and isopentane or other solvents and therefore their use is limited. The esterified polysiloxane may have improved properties but is quite expensive.

Accordingly, skin protection products comprising cosmetic formulations that reduce the disadvantages of conventional silicone compounds and maintain desirable properties of water resistance, durability, retention, skin feel and gloss as described above are desirable.

Hair is washed with shampoo, rinsed, protected with hair dressing and fixed with mousse and hair spray. In some cases, perm solutions and hair dyes are used. The compositions used for hair treatment contain cosmetic formulations and combine with existing vegetable oils, animal oils, mineral oils, synthetic oils and the like to form hair protection products.

With the recent advances in the silicone polymer industry, various polysiloxane polymers have been formulated as the main component of cosmetic formulations used in hair care products because of their desirable properties.

Examples of such hair protection products are as follows: shampoos containing dimethyl silicone, diethyl silicone or methylphenyl silicone to provide a rinse effect (US Pat. No. 2,826,511); Hair cosmetics containing diol derivatives or branched aliphatic alcohols and methyl polysiloxane (Japanese Patent Laid-Open No. 47923/1977); Vinyl pyrrolidine-silicon copolymer-containing conditioning lotion (Japanese Patent Laid-Open No. 57337/1977); Quaternary nitrogen-containing cation-modified silicone-containing cosmetics (JP-A-66506 / 1980); A hair treatment composition comprising an anionic polymer compound, a cationic surfactant, and an oxyalkylene-modified organopoly siloxane (Japanese Patent Publication No. 108811/1980); Hair conditioner compositions comprising polyoxyalkylene-modified organopolysiloxanes and water-containing ethanol or anhydrous ethanol (Japanese Patent Laid-Open No. 136214/1980); Hair cosmetics comprising water, ethanol and a phosphorus ester salt of polyoxypropylene polyatomic-alcohol ether and polyoxyalkylene methylpolysiloxane (Japanese Patent Laid-Open No. 16405/1981); Hair cosmetics containing organosiloxane polyoxy alkylene copolymers (Japanese Laid-Open Patent Publication No. 22812/1981); Hair conditioner compositions comprising polysiloxanes containing aminoalkyl groups and hydroxy groups, cationic polymers and aqueous carriers (JP-A-45406 / 1981); Anionic surfactants, cationic polymers and silicone derivatives (dimethyl polysiloxane, methylphenyl polysiloxane, polyether modified silicone oil, epoxy modified silicone oil, fluorine modified silicone oil, alcohol modified silicone oil and alkyl modified silicone oil) Shampoo compositions (Japanese Laid-Open Patent Publication No. 72095/1981); Hair cosmetics comprising an olefin liquid polymer, dimethyl polysiloxane, a polymeric chain emulsifier and water (Japanese Patent Laid-Open No. 86113/1981); Hair cosmetics including quaternary ammonium salts, higher alcohols and hydrophobic silicones (Japanese Patent Laid-Open No. 92808/1981); Amphoteric acrylic resins, polyoxyalkylene modified organopolysiloxanes and polyethylene glycols (Japanese Patent Laid-Open No. 92811/1981); Hair conditioners comprising organopolysiloxanes having as main components at least one aminoalkyl group and at least one oxyalkylene group, polyoxyalkylene or hydroxyalkyl group (Japanese Patent Laid-Open No. 7702/1983); Cosmetic products containing amphoteric silicone oils and polyoxyalkylene-modified polysiloxanes (Japanese Patent Laid-Open No. 126209/1985); Hair conditioning compositions comprising silicone conditioners, dimethyl silicone copolymers, lipid vehicle formulations, cationic surfactant vehicle formulations and water (Japanese Patent Laid-Open No. 6/1986); Hair coloring compositions containing a colorant component, silicone oil and water (Japanese Patent Laid-Open No. 83111/1986); And cosmetics for hair comprising organo silicone resin and volatile hydrocarbon oil (Japanese Patent Laid-Open No. 158914/1986).

Hair protection products containing dimethyl polysiloxane as one component do not solvate dimethyl polysiloxane in an aqueous solvent, so a large amount of emulsifier may impair the transparency of the emulsified liquid, irritate the skin and lower the water resistance after application to the hair There is a problem that requires. Dimethyl polysiloxanes also tend to generate static that tends to attract dust and soot and cause hair plies.

Polysiloxanes having aminoalkyl groups and / or quaternary nitrogen-containing groups significantly improve the antistatic effect, water resistance and durability but do not have all of these properties.

Many hair protection products containing dimethyl polysiloxanes with polyoxyalkylene groups have been proposed and they are successful in preventing the generation of static electricity, but water resistance, miscibility, bulky finish, emulsification, foamability are not sufficient.

Thus, it reduces the disadvantages of conventional dimethyl polysiloxanes or various functional group-containing polysiloxanes, and reduces the desired hair antistatic effect, moisturizing effect, combability, gloss finish, voluminousness finish, voluminous finish, wetting finish, emulsifying effect. And hair care products comprising cosmetic formulations having a foaming effect.

According to the present invention there is provided a cosmetic formulation comprising a non-hydrolyzed block copolymer having a straight chain polysiloxane-polyoxy alkylene block as repeating unit, suitable for use in skin care products and hair care products.
