Abstract
The invention relates to a styling composition comprising, in a physiologically acceptable liquid medium, the combination of at least one film-forming fixing polymer and of at least one crystalline hot-melt polymer which is soluble in the said medium and which has a crystalline melting temperature, measured by differential scanning calorimetry, of between 30° C. and 80° C., and to a process for the thermal remodelling of the hair using this composition.
Claims8
Styling composition comprising, in a physiologically acceptable medium, the combination
- (a) of at least one film-forming fixing polymer and
- (b) of at least one crystalline hot-melt polymer which is soluble in the said medium and which has a crystalline melting temperature, measured by differential scanning calorimetry, of between 30° C. and 80° C.
Styling composition according to any one of the preceding claims, characterized in that the said film-forming fixing polymer is chosen from anionic, cationic, amphoteric or nonionic film-forming fixing polymers.
Styling composition according to any one of the preceding claims, characterized in that the ratio by weight of the said hot-melt polymer (b) to the fixing polymer (a) is between 1/10 000 and 3/1, preferably between 1/200 and 3/5.
Styling composition according to any one of the preceding claims, characterized in that the total amount of fixing polymer (a) and of hot-melt polymer (b) is between 1% and 20% by weight with respect to the final styling composition.
Styling composition according to any one of the preceding claims, characterized in that the said physiologically acceptable liquid medium comprises a solvent chosen from water, lower C1-4 alcohols, such as ethanol or isopropanol, acetone, methyl ethyl ketone, ethyl acetate, methyl acetate, butyl acetate, diethoxyethane, dimethoxyethane, C6-10 alkanes or mixtures of these compounds.
Process for remodelling the hair, which consists
- (1) in applying, to dry or wet hair, a styling composition according to any one of the preceding claims,
- (2) in giving the hair the desired shape by heating the hair by means of an appropriate heat source to a temperature close to or greater than the crystalline melting temperature of the crystalline hot-melt polymer present in the styling composition, and
- (3) in allowing the hair to cool to a temperature below the said crystalline melting temperature of the said crystalline hot-melt polymer,
- it being possible for these latter two stages to be repeated many times without the, introduction of additional styling composition.
