Abstract
The present invention provides a lip cosmetic that has excellent secondary adhesion resistance effect immediately after the application and is excellent in gloss durability and stability. The lip cosmetic of the present invention is characterized by comprising the following components (a) to (d): (a) 10 to 30 mass % of hydrogenated polyisobutene; (b) 30 to 70 mass % of one or more kinds of methyl phenyl silicones that separate when mixed with (a) at 25° C.; (c) 0.5 to 8 mass % of a lipophilic surfactant that does not separate both when mixed with component (a) and when mixed with component (b) at 90° C.; and (d) 5 to 12 mass % of a wax.
Claims14
A lip cosmetic comprising:
- (a) 10 to 30 mass % of hydrogenated polyisobutene;
- (b) 30 to 70 mass % one or more kinds of methyl phenyl silicones that separate when mixed with (a) at 25° C. wherein the methyl phenyl silicone(s) comprises trimethyl pentaphenyl trisiloxane and optionally one or more selected from the group consisting of diphenylsiloxy phenyl trimethicone and diphenyl dimethicone;
- (c) 0.5 to 8 mass % of one or two kinds of lipophilic surfactants that does not separate both when mixed with component (a) and when mixed with component (b) at 90° C. wherein the lipophilic surfactant(s) is selected from the group consisting of sorbitan sesquiisostearate and propylene glycol monostearate;
- (d) 5 to 12 mass % of a wax;
- and
- 5 mass % or less of a silicone-treated pearlescent agent as a coloring material.
A lip cosmetic comprising the following components and none of volatile oil components:
- (a) 10 to 30 mass % of hydrogenated polyisobutene;
- (b) 30 to 70 mass % of at least two kinds of methyl phenyl silicones that separate when mixed with (a) at 25° C. wherein the methyl phenyl silicones comprise trimethyl pentaphenyl trisiloxane and diphenylsiloxy phenyl trimethicone, and optionally diphenyl dimethicone, wherein said two kinds of methyl phenyl silicones include the diphenylsiloxy phenyl trimethicone at 1 to 17 mass % relative to the total amount of the cosmetic;
- (c) 0.5 to 8 mass % of one or two kinds of lipophilic surfactants that does not separate both when mixed with component (a) and when mixed with component (b) at 90° C. wherein the lipophilic surfactant(s) is selected from the group consisting of sorbitan sesquiisostearate and propylene glycol monostearate;
- (d) 5 to 12 mass % of a wax;
- and
- 5 mass % or less of a silicone-treated pearlescent agent as a coloring material.
