A cosmetic composition for topical application to the skin and/or hair includes, optionally in a cosmetically or pharmaceutically acceptable vehicle, particles which enclose a cosmetically-effective benefit agent active at a target location accessible by application to the skin and/or hair, and which have means to bind to an organic surface at the target location. In particular, the particles are liposomes and have means for binding to microorganisms present on the skin and/or hair, for example those responsible for skin disorders, scalp irritation, and underarm and foot odour.

Cosmetic composition

Cosmetic composition for topical application to skin or hair

The invention relates to an oral composition for the care of the mouth to inhibit oral bacteria and to neutralize acids, produced by oral bacteria. This achieved by inclusion in the oral composition of a hydrotalcite-like material of a particular general formula, typical representatives being zinc aluminum hydrotalcite (Zn.sub.12 Al.sub.6 (OH).sub.36 (NO.sub.3).sub.6 H.sub.2 O) and copper magnesium aluminum hydrotalcite (Cu.sub.3 Mg.sub.9 Al.sub.4 (OH).sub.32 Cl.sub.4 H.sub.2 O). These hydrotalcite-like materials show significant anti-plaque activity. Typical examples of oral compositions are toothpastes and mouth rinses.
