Aqueous polyamine-containing carrier systems for water-insoluble materials

A process for making an aqueous delivery system which is both stable, and clear to slightly limpid in appearance, involving the steps of:

• (a) providing a carrier composition containing:
• (i) at least one polyamine compound comprising at least two amino groups, (ii) at least one nonionic surfactant and, (iii) at least one anionic silicone;
• (b) providing at least one water-insoluble ingredient;
• (c) optionally, heating the composition of step (a) to form a heated mixture;
• (d) adding (b) to either step (a), step (c) or both step (a) and (c);
• (e) adding an aqueous solution to either (c) or (d) to form a diluted mixture;
• and (f) cooling the diluted mixture to form the aqueous delivery system;
• wherein (b) is present in an amount of about 4% by weight, or more, based on the weight of the aqueous delivery system.

A process for treating a keratinous substrate comprising contacting the keratinous substrate with a composition containing:

• (a) at least one polyamine compound comprising at least two amino groups;
• (b) at least one nonionic surfactant;
• (c) at least one anionic silicone;
• and (d) at least one water-insoluble material which is present in an amount of about 4% by weight, or more, based on the weight of the composition.
