Cross-reference to related orders None.

BACKGROUND OF THE INVENTION The present invention relates to skin and hair cleansing compositions comprising: (A) a film-forming organopolysiloxane, (B) a cooling agent and (C) a cleaning agent.

Skin and hair cleansing compositions are commonly used for cleansing. Additional benefits may, however, be conferred by such compositions and include: conditioning, moisturizing, smoothing and exfoliating, depending on the ingredients present in the compositions in addition to the cleaning base component.

Organopolysiloxane compounds are used in skin and hair cleansing compositions to impart a variety of benefits such as improved thickenings, to improve skin and hair feel or to detangle hair. Cooling agents are used in cleaning compositions to give the user a refreshing and clean feel.

It was some regions where the weather is humid and hot, the effect of cleaning skin and hair can be quickly lost by the action of temperature and humidity. It is therefore an object of the invention to extend the feeling of cleanliness from a skin and hair composition comprising a film-forming organopolysiloxane compound and a cooling agent.

Organopolysiloxane film-forming compounds include polymers which, by themselves, form films upon drying. The film may be macroscopically continuous and adherent to keratin materials and optionally cohesive. In some cases, the film may have cohesion and mechanical properties such that it is possible for the film to be treated and isolated for manipulation upon preparation, for example, when said film is produced by flow on non-apparent surfaces such as surfaces. coated with or silicone. The film can be characterized by various parameters such as stickiness, smoothness or the presence of cracks.
