Abstract
An aqueous liquid cleansing and moisturising composition comprising a surface active agent and a benefit agent in which the surface active agent and benefit agent are separate but combinedly dispensable from a single packaging means in a predetermined ratio as discrete domains. Separating the benefit agent from the surface active agent results in improved deposition of the benefit agent.
Claims8
An aqueous liquid cleansing and moisturizing composition comprising:
- (a) 50% to 99.9% by wt. of a base formulation comprising 1% to 35% by wt. of a surface active agent selected from the group consisting of anionic, nonionic, zwitterionic and cationic surface active agents, soap and mixtures thereof;
- and
- (b) 0.1% to 50% by wt. of a benefit agent selected from the group consisting of silicone oils, gums, fats, oils, waxes, hydrophobic plant extracts, hydrocarbons, fatty acids, alcohols, esters, essential oils, lipids, phospholipids, vitamins, sunscreens, and mixtures thereof;
- wherein the benefit agent and the base formulation comprising said surface active agent are physically separate such that the base formulation and the benefit agent are not in direct contact with one another but are nonetheless dispensable from a single packing means which comprises both the base formulation and the benefit agent as individual stripes;
- wherein each stripe comprises either said benefit agent or said base formulation;
- wherein each stripe has a width of at least 1,000 microns;
- and
- wherein (a) and (b) are not post mixed prior to use.

A method of using a liquid cleansing and moisturizing composition comprising:
- (a) 50% to 99.9% by weight of a base formulation comprising 1% to 35% by weight of a surface active agent selected from the group consisting of anionic, nonionic, zwitterionic and cationic surface active agents, soap and mixtures thereof;
- and
- (b) 0.1% to 50% by weight of a benefit agent selected from the group consisting of silicone oils, gums, fats, oils, waxes, hydrophobic plant extracts, hydrocarbons, fatty acids, alcohols, esters, essential oils, lipids, phospholipids, vitamins, sunscreens, and mixtures thereof;
- wherein said method comprises:
- i) dispensing the base formulation containing said surface active agent and the benefit agent from a packaging means;
- and
- ii) applying the base formulation and the benefit agent to the human body;
- wherein said base formulation and said benefit agent are physically separate such that said base formulation and said benefit agent are not in direct contact with one another but are nonetheless combinedly dispensable from a single packaging means as individual stripes;
- wherein each stripe comprises either said benefit agent or said base formulation;
- wherein each stripe has a with of at least 1,000 microns;
- and
- wherein (a) and (b) are not post mixed prior to use.
