Abstract

Poly(isoprene-graft-maleic acid methoxy poly[ethylene oxide]) (PIP-g-MaMPEO, CAS: 1246080-53-4) is a versatile material that can be used in a wide range of different personal care, cosmetic and health care products. The use of the polymer in a broad selection of such products for application to the skin, hair and nails is discussed to illustrate its benefits. These include nail, lip, eye and face make-up, skin, sun, hair and wound care products amongst others.

Multifunctional Polymer Technology for use in Personal Care Products

Extensive safety data exists to prove the safety of the material and its lack of irritancy, making it particularly suitable for products designed for sensitive skin or that might come into contact with the lips or ocular area.

The polymer is sold for use in personal care under the RevCare™ brand (for instance Skin Sense™ and Hair Sense™). It can be listed under the INCI name Isoprene/MA/Methoxy PEG-40 Copolymer sometimes in combination with PEG-40 Methoxy Ether and/or PEG-40.

As discussed within this disclosure the polymer has a number of particularly useful applications in personal care and is thus provided for use in cosmetics, skin care, hair care, oral care amongst other applications.

Formats of the Polymer

Polymer PIP-g-MaMPEO is available in the format of a solid material which can be incorporated directly into products by dissolution or by melting. Given that the polymer is predominantly hydrophobic this format is often very suitable for the addition of product to formulations composed chiefly of oils, waxes and non-polar solvents. Alternatively it may be suitably added to the oil phase of an emulsion product containing water.

It can be supplied as a mixture with methoxy poly(ethylene oxide) or poly(ethylene oxide) present and any reference to PIP-g-MaMPEO should be taken to include both the polymer PIP-g-MaMPEO in isolation, together with mixtures of PIP-g-MaMPEO with methoxy poly(ethylene oxide) or poly(ethylene oxide).

The polymer may be blended with many active and other cosmetic ingredients prior to use (e.g. by melting and stirring the polymer an ingredients as appropriate).

Water Based Formats

Polymer PIP-g-MaMPEO is not water soluble in isolation but it can be converted into a number of different water based formats. For instance the polymer can be converted into a paste by heating it in water and milling or dispersing the polymer with a mixer to pro...
