Abstract:
PROBLEM TO BE SOLVED: To use a thermostabilizing microcapsule containing a heat absorbing crystal compound for protecting a cosmetic or a medicine composition against an action of heat change. SOLUTION: A thermostabilizing microcapsule containing at least one crystal compound exhibiting 75-330 kJ/kg melt enthalpy (ΔHf) measured by differential scanning calorimetry so as to protect a cosmetic or a medicine from an action of heat change is used. This cosmetic or medicine composition contains the thermostabilizing microcapsule. The microcapsule contains preferably a partially or wholly crystalline compound in a coating free from leakage and absorbs a large amount of heat known as a latent heat of fusion when heated to a temperature close to the melting point of the compound. Consequently, the temperature of the present environment of the microcapsule can be automatically controlled in a temperature range close to the melting point of the compound regardless of the change of external temperature for a fixed time.

PROBLEM TO BE SOLVED: To provide a cosmetic composition removable with warm water and resistant to cold water. SOLUTION: The cosmetic composition contains a film-forming polymer and a thermal transition agent changing its state at a transition temperature Tt falling within the range of from 25 deg.C to 80 deg.C. The thermal transition agent is insoluble in water maintained at a temperature lower than the transition temperature Tt and the film-forming polymer and the thermal transition agent are selected to give the composition capable of forming a thin film at the temperature of keratin substance. The composition has a water-intake (Rc) of >=15% in warm water maintained to 40 deg.C and satisfies the formula: Rc-Rf>=3% wherein Rf is water-intake in cold water maintained to 20 deg.C.

SOLUTION: This film-forming cosmetic composition uses at least 5 wt.% based on the total amount of the composition of a first hydrophobic film forming polymer and at least one heat transition agent which can be subjected to a phase change at a transition temperature Tt selected from a temperature range from 25 deg.C to 80 deg.C and is insoluble in water maintained a temperature lower than the transition temperature Tt in a pathologically acceptable medium. The composition is resistant to cold water and/or removable with hot water and is used for obtaining a film to be applied to a keratin substance.
Abstract:
PROBLEM TO BE SOLVED: To obtain a cosmetic composition which can be removed by hot water and has fine resistance against cold water at the same time. SOLUTION: This cosmetic composition consists of a composition containing a film-forming polymer and a thermal transition agent which undergoes the change of the state at a transition temperature Tt selected from the temperature range of 25 deg.C to 80 deg.C in a physiologically permissible medium. The above thermal transition agent is insoluble in water held at a temperature below the above transition temperature Tt. The composition containing the above film- forming polymer and thermal transition agent in sufficient amounts can form a film of which the resistance (Rc) against hot water (40 deg.C) is less than 15 min at the temperature of keratin substance and the resistance (Rf) against cold water (20 deg.C) is Rf-Rc>=8 min and so the composition is applied to the keratin substance as a cosmetic care or a method of makeup for keratin substance.

PROBLEM TO BE SOLVED: To obtain a copolymer useful as a composition for cosmetics or dermatoses by including a graft unit of a hydrophobic macromonomer in a copolymer prepared by the radical polymerization or polycondensation. SOLUTION: This graft copolymer comprises a copolymer having a skeleton (S) obtainable by the radical polymerization or polycondensation and 0-30 deg.C glass transition temperature Tg and is obtained by including at least one graft unit composed of a hydrophobic macromonomer (M) having a higher glass transition temperature T'g than 25 deg.C in the skeleton S.
