Abstract

An oily make-up cosmetic composition which can provide an excellent feeling upon use, a superior make-up effect, and good stability over time is disclosed. The cosmetic composition is normally of a solid form, and comprises a silicone gel composition and a cosmetic powder material, both dispersed in an oil base. The composition may further comprises an aqueous gel of water-soluble polymer containing glycerine.

Claims

1. An oily make-up cosmetic comprising:

(A) an oil base which comprises

(i) a cosmetically acceptable semi-solid or liquid oil selected from the group consisting of mineral oils, plant oils, animal oils, fatty acids, fatty acid esters and higher alcohols, and

(ii) 5-40% by weight, based on (A), of a cosmetically acceptable solid oil having a melting point of 40°

C. or higher, a cosmetically acceptable oil gelling agent selected from the group consisting of mineral clays, starch fatty acid esters, lipophilic sucrose fatty acid esters, N-acylamino acid amides, N-acylamine acid amine salts, metallic soaps, and a mixture thereof;

(B) a silicone gel composition which comprises;

(a) a three-dimensional partially crosslinked organopolysiloxane polymeric compound comprising R₂ SiO units and RSiO₁.5, units, which may also contain R₃ SiO₀.5 units and/or SiO₂ units, wherein R independently represents a hydrogen atom, an alkyl group, an aryl group or an unsaturated aliphatic group and the ratio of R₂ SiO units to RSiO₁.5 units is 1;

1 to 30;

1, or an organopolysiloxane polymeric compound which is insoluble but swells in silicone oil which is prepared by the addition polymerization of (i) an organohydrogenpolysiloxane and (ii) an organopolysiloxane having unsaturated aliphatic groups, wherein the amount of hydrogen and unsaturated aliphatic groups in (i) or (ii) is 1-20 mol% when the organopolysiloxane has a linear or branched structure, and is 1-50 mol% when the organopolysiloxane has a cyclic structure, and contains a partial three dimensional crosslinked structure and

(b) a silicone oil having a viscosity of about 50 cs or less,

wherein the weight ratio of (a) and (b) is 5/95 to 30/70, wherein the weight ratio of (A) and (B) is 55/45 to 65/35; and

(c) a cosmetic powder material.

2. The oily make-up cosmetic according to claim 1, wherein (A) is present in an amount of 30-80 wt.%, (B) is present in an amount of 10-40 wt.% and (C) is present in an amount of 1-40 wt.%.

3. The oily make-up cosmetic according to claim 1, wherein (A) is present in an amount of 40-70 wt.%, (B) is present in an amount of 20-30 wt.% and (C) is present in an amount of 15-25 wt.%.

4. The oily make-up cosmetic according to anyone of claims 1, 2 or 3, wherein the partially cross-linked organopolysiloxane polymeric compound (a) is insoluble in benzene and has a three dimensional structure and in which benzene of an equivalent or more amount of the organopolysiloxane polymeric compound itself may be contained.

5. The oily make-up cosmetic according to claim 1, wherein the weight ratio of (a) and (b) is 10/90 to 25/75.

6. The oily make-up cosmetic according to claim 1, wherein said cosmetic powder material is selected from the group consisting of inorganic white pigment, inorganic colored pigment, organic powder and pearling agent.

7. An oily make-up cosmetic comprising:

(A) an oil base which comprises

(i) a cosmetically acceptable semi-solid or liquid oil selected from the group consisting of mineral oils, plant oils, animal oils, fatty acids, fatty acid esters and higher alcohols, and

(ii) 5-40% by weight, based on (A), of a cosmetically acceptable solid oil having a melting point of 40°

C. or higher, a cosmetically acceptable oil gelling agent selected from the group consisting of mineral clays, starch fatty acid esters, lipophilic sucrose fatty acid esters, N-acylamino acid amides, N-acylamine acid esters, N-acylamino acid amine salts, metallic soaps, and a mixture thereof;

(B) a silicone gel composition which comprises;

(a) three-dimensional partially crosslinked organopolysiloxane polymeric compound comprising R₂ SiO units and RSiO₁.5, units, which may also contain R₃ SiO₀.5 units and/or SiO₂ units, wherein R independently represents a hydrogen atom, an alkyl group, an aryl group or an unsaturated aliphatic group and the ratio of R₂ SiO units to RSiO₁.5 units is 1;

1 to 30;

1, or an organopolysiloxane polymeric compound which is insoluble but swells in silicone oil which is prepared by the addition polymerization of (i) an organohydrogenpolysiloxane and (ii) an organopolysiloxane having unsaturated aliphatic groups, wherein the amount of hydrogen and unsaturated aliphatic groups in (i) or (ii) is 1-20 mol% when the organopolysiloxane has a linear or branched structure, and is 1-50 mol% when the organopolysiloxane has a cyclic structure, and contains a partial three dimensional crosslinked structure and

(b) a silicone oil having a viscosity of about 50 cs or less,

wherein the weight ratio of (a) and (b) is 5/95 to 30/70, wherein the weight ratio of (A) and (B) is 55/45 to 65/35; and

(C) a cosmetic powder material; and

(D) 5-30 wt.%, based on the composition, of an aqueous gel of acrylic water-soluble polymer containing 30-70% by weight of glycerine, said polymer exhibiting a viscosity increase by the addition of an alkali.

8. The oily make-up composition according to claim 7, wherein (A) is present in an amount of 30-80 wt%, (B) is present in an amount of 10-40 Wt.%, (C) is present in an amount of 1-40 Wt.% and (D) is present in an amount of5-30 wt.%.
