Cosmetic or Personal Care Composition Comprising a Polymer Comprising Oxazolidon Groups

Abstract

The invention relates to a cosmetic or personal care composition comprising a polymer which polymer comprises oxazolidon groups. Examples of cosmetic and personal care compositions include hair spray compositions, mousses, gels, lotions, tonics, shampoos, conditioners, rinses, hand and body lotions, facial moisturizers, sunscreens, anti-acne preparations, topical analgesics, mascara's, eyeliners, blush, liquid lip color, nail polish and foundations.

1 . A cosmetic or personal care composition comprising a polymer which polymer comprises oxazolidon groups characterized in that the oxazolidon groups are present in the main chain of the polymer. 
     
     
         2 . A cosmetic or personal care composition according to  claim 1  characterized in that the polymer further comprises oxazolidon groups in side chains or as side groups. 
     
     
         3 . A cosmetic or personal care composition according to  claim 1  characterized in that the polymer is formed from a reaction mixture comprising at least one epoxy functional compound and at least one isocyamate functional compound. 
     
     
         4 . A cosmetic or personal care composition according to  claim 3 , characterized that the reaction mixture comprises a diepoxide and a diisocyante. 
     
     
         5 . A cosmetic or personal care composition according to  claim 3 , characterized in that the epoxy functional compound is selected from epoxy terminated polyethylene glycol, epoxy terminated polypropylene glycol and epoxy terminated polytetrahydrofuran, diglycidyl ethers of ethylene glycole, diethylene glycol, neopentylglycol, or butane diol. 
     
     
         6 . A cosmetic or personal care composition according to  claim 3 , characterized in that the isocyanate functional compound is selected from tolylene-2,4-diisocyanate, tolylene-2,6-diisocyanate, isophorone diisocyanate, diphenyl methane diisocyanate, hydrogenated diphenyl methane diisocyaiate, hexamethylene-1,6-diisocyanate. 
     
     
         7 . A cosmetic or personal care composition according to  claim 1 , characterized in that the oxazolidon group comprising polymer further comprises at least one hydroxyl functional compound and/or at least one amine functional compound. 
     
     
         8 . A cosmetic or personal care composition according to  claim 1 , characterized in that the polymer is formed in a process wherein in the first step the epoxy functional compound and the isocyanate functional compound are reacted to form a polyoxazolidon group containing polymer precursor and wherein in one or more further steps the polymer precursor is reacted with at least one hydroxyl functional compound and/or at least one amine functional compound. 
     
     
         9 . A cosmetic or personal care composition according to  claim 7 , wherein the hydroxyl functional compound is an amino alcohol. 
     
     
         10 . A cosmetic or personal care composition according to  claim 7 , wherein the hydroxy and/or amine functional compound comprises at least one ionogenic or ionic group per molecule. 
     
     
         11 . A cosmetic or personal care composition according to  claim 10 , wherein the ionogenic or ionic group is an aniogenic or anionic group. 
     
     
         12 . Polymer comprising the reaction product of an isocyanate functional oxazolidon polymer and an amino alcohol. 
     
     
         13 . Polymer comprising an oxazolidon group and a residue of an amine functional compound or a hydroxy functional compound having at least one ionogenic or ionic group.
