Abstract
The present disclosure relates to a cosmetic composition comprising, in a physiologically acceptable medium, at least one compound which gives the cosmetic composition a thermal profile having a melting peak wherein the mid-height width Lf is less than or equal to 20° C., and wherein the composition is heat-stable. The present disclosure also relates to the process of depositing a film on the keratin fibers, wherein the film is homogenous and/or has improved curling properties, comprising applying the cosmetic composition disclosed herein to keratin fibers.
Claims16
A cosmetic composition comprising, in a non-toxic medium, polystearyl acrylate having a thermal profile having a melting peak wherein the mid-height width Lf is less than or equal to 20° C.,
- wherein said thermal profile is determined by heating an empty crucible and a crucible containing a sample of said composition and measuring the variation of the difference in power absorbed by the empty crucible and by the crucible containing the sample as a function of temperature;
- and
- wherein the cosmetic composition itself has a thermal profile having a melting peak wherein the mid-height width Lf is less than or equal to 20° C.,
- and wherein the cosmetic composition further comprises a film-forming polymer selected from:
- synthetic polymers resulting from the radical-mediated polymerization of at least one monomer selected from acrylic acid, methacrylic acid, methyl methacrylate, butyl methacrylate, 2-ethylhexyl methacrylate, hydroxyethyl acrylate, hydroxyethyl methacrylate, 2-hydroxypropyl acrylate, and 2-hydroxypropyl methacrylate;
- gum arabic;
- polyurethanes;
- polyesters;
- aqueous dispersions of polymers selected from acrylic, polyurethane, and hybrid polymers;
- polymers of cellulose selected from hydroethylcellulose, hydroxypropylcellulose, methylcellulose, and carboxymethylcellulose;
- polyvinylpyrrolidones;
- polyurethane-polyvinylpyrrolidones;
- and
- copolymers of vinyl pyrrolidone and of caprolactam;
- copolymers of vinylpyrrolidone and of vinyl acetate;
- copolymers of vinylpyrrolidone and of ethyl methacrylate;
- butylated polyvinylpyrrolidine;
- copolymers of vinylpyrrolidone and of eicosene;
- copolymers of vinylpyrrolidone and of hexadecene;
- copolymers of vinylpyrrolidone and of triacontene;
- and copolymers of vinylpyrrolidone and of styrene.
