EMULSIFICATION SYSTEMS, EMULSIONS AND WET WIPES CONTAINING SUCH EMULSIONS

摘要

A method of making an oil-in-water emulsion is described in which an oil emulsifier and a polysaccharide emulsion stabiliser, which stabiliser comprises a Xanthan polysaccharide and a polyglucomannan polysaccharide, is dispersed in an oil,. The oil-based dispersion so formed is then combined with water, preferably at low temperature and under low shear conditions, to form an oil-in-water emulsion. The polysaccharide emulsion stabiliser and optionally oil emulsifier may be dispersed directly into a relatively polar oil to form the oil-based dispersion or, alternatively, into a relatively polar non-aqueous liquid medium, which medium then being mixed with the oil before it is combined with the water to form the emulsion. The oil-in-water emulsions are particularly useful in personal care and cosmetic applications such as sprays, body moisturisers, sun screens and wet wipes for cosmetic or personal hygiene cleaning uses.
