Method of treating skin with a composition comprising a phosphoric triester and a skin activating component

Abstract

The invention relates to a cosmetic comprising (A) a phosphoric triester represented by the general formula (1): wherein R 1 and R 2 are independently an alkyl group having 1 to 8 carbon atoms, R 3 is an alkyl group having 1 to 4 carbon atoms, X, Y and Z are independently an alkylene group having 2 or 3 carbon atoms, l and m are independently a number of 1 to 10, and n is a number of 0 to 10, and (B) a skin activating component. The cosmetic is excellent in moisturizing effect; the effects of preventing and remedying skin roughness; the effects of preventing the firm and resilient skin from declining and remedying the declined skin; the effects of preventing a complexion from dulling and remedying a dull looking face; the effects of preventing and remedying the conspicuousness of pores of the skin and pimples caused by excess sebum, microorganisms or keratonosis; the effects of preventing development of wrinkles and remedying the wrinkled skin; and the effects of preventing and remedying spots and freckles, and moreover gives users a pleasant feeling upon use.

         7 . A method of treating the skin comprising applying to the skin a cosmetic composition comprising the following components (A) and (B): 
 (A) at least one phosphoric triester represented by the general formula (1):                          wherein R 1  and R 2  are the same or different from each other and independently a linear or branched alkyl group having 1 to 8 carbon atoms; R 3  is a linear or branched alkyl group having 1 to 4 carbon atoms; X, Y and Z are the same or different from one another and independently a linear or branched alkylene group having 2 or 3 carbon atoms; Q and m are the same or different from each other and independently a number of 1 to 10, and n is a number of 0 to 10; and    (B) a skin activating component,    wherein the component (B) is at least one selected from the group consisting of    ceramides, pseudoceramides, hydrophilic moisturizers, amino acids, plant extracts, whitening agents, anti-inflammatory agents, singlet oxygen scavengers, antioxidants, water-soluble polymers, higher alcohols, sterols, blood circulation-facilitating agents, sebum secretion inhibitors, softening agents, anti-microbial agents and keratolytic agents, and    wherein the phosphoric triester is present in an amount that enhances the effect of the skin activating component when applied to the skin.    
     
     
         8 . The method of treating the skin according to  claim 7 , wherein the phosphoric triester of the component (A) is a compound in which in the general formula (1), R 1 , R 2  and R 3  are independently an alkyl group having 2 to 4 carbon atoms, X, Y and Z are all ethylene groups, and V, m and n are independently a number of 1 to 4.  
     
     
         9 . The method of treating the skin according to  claim 7 , wherein the phosphoric triester of the component (A) is a compound in which in the general formula (1), R 1  and R 2  are independently an alkyl group having 2 to 6 carbon atoms, R 3  is an alkyl group having 2 to 4 carbon atoms, X and Y are both ethylene groups, n is a number of O, and C and m are independently a number of 1 to 5.  
     
     
         10 . The method of treating the skin according to  claim 7 , wherein the phosphoric triester is selected from the group consisting of: 
 (a) tris(butoxyethyl)phosphate, (b) tris(butoxyethoxyethyl)phosphate, (c) tris(butoxyethoxyethoxyethyl)phosphate, (d) tris(ethoxyethoxyethyl)phosphate, (e) tris(ethoxyethoxyethoxyethyl)phosphate, (f) tris(methoxyethoxyethyl)phosphate, (g) tris(methoxyethoxyethoxyethyl)phosphate,                          
     
     
         11 . The method of treating the skin according to  claim 7 , wherein the phosphoric triester is present in an amount of 1 to 50% by weight of the composition.  
     
     
         12 . The method of treating the skin according to  claim 7 , wherein the phosphoric triester is present in an amount of 2 to 25% by weight of the composition.
