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

Enzyme electrodes having the enzyme enclosed within liposomes supported on, or in a membrane and immobilized therein are provided. The liposomes may be made using lipids and conveniently by 'reverse phase evaporation'. The enzyme electrodes incorporate conventional electrode elements, e.g., THE Clark electrode pair (Platinum/Silver) and additional membranes or screens, and used particularly in amperometric measurements. The enzyme can be an oxidase and is useful for measurement, directly or indirectly, of low molecular weight species generated by enzymic action, and effective for study of biological fluids.

Electrolytic analytical methods

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 odor.
