Stability of oil refining water emulsion

摘要

Stable aqueous emulsions of essential oils consisting of - 1 to 45 parts by weight of an essential oil - 0.01 to 1 part by weight of a nonionic emulsifier chosen from sugar glycerides and sugar esters - 0.2 to 1.5 parts by weight of xanthan gum - and the residue to 100 parts by weight of water. They are prepared by dissolving xanthan gum in the nonionic emulsifier and dispersion of the essential oil before or after the addition of xanthan gum. Use for the preparation of aromatising concentrates.
