Abstract
A sheet-like cosmetic is formed by impregnating a laminated sheet having two or more non-woven fabric layer composed of ultra-fine fibers with a cosmetic containing 1 wt % or more of a specific liquid oil component. An average diameter is specified, and select portions are impregnated with a cosmetic containing 1-30 wt % of one, two or more liquid oil components selected from hydrocarbon oils, higher alcohols, higher fatty acids, ester oils, liquid fats/oils, and silicone oils.
Claims10
A sheet-like cosmetic, comprising:
- a sheet that (a) is a laminated sheet composed of two or more non-woven fabric layers, (b) has a non-woven fabric layer composed of ultra-fine fibers having an average diameter of 1-500 nm at a skin contact surface, and (c) additionally has a non-woven fabric layer composed of fibers having an average diameter larger than that of the ultra-fine fibers used in the non-woven fabric layer at the skin contact surface having an average diameter of 1-500 nm wherein which sheet is impregnated with a cosmetic containing 1-30 wt % of one, two or more liquid oil components selected from hydrocarbon oils, higher alcohols, higher fatty acids, ester oils, liquid fats/oils, and silicone oils.
A sheet-like cosmetic system, comprising:
- a sheet that further comprises:
- (a) a laminated sheet, composed of at least two non-woven fabric layers;
- (b) at least one said non-woven fabric layer composed of ultra-fine fibers having a first average diameter of 1-500 nm proximate an operative skin contact surface, and
- (c) at least one additional non-woven fabric layer composed of fibers having a second average diameter larger than that of the ultra-fine fibers used in the non-woven fabric layer at the skin contact surface having said first average diameter of 1-500 nm, and
- (d) wherein said sheet is impregnated with an impregnation amount of a cosmetic containing 1-30 wt % of one, two or more liquid oil components selected from a group consisting of:
- hydrocarbon oils, higher alcohols, higher fatty acids, ester oils, liquid fats/oils, and silicone oil;
- (e) wherein, an impregnation mass of said impregnation amount of said cosmetic impregnated into said sheet is 5-15 times a mass of said laminated sheet.
