Ir6 (Cosmetics, Toiletry and Fragance Association, Inc. 7th edition 1997). Unless stated otherwise, viscosity is measured using a Brookfield viscometer (1,000-20,000 cps, spindle Ns 5.20 rpm, run at 60 seconds, 25 degrees C) 961-00-IR 6961-00-1- . A stable dispersion of behenyl alcohol, of low viscosity, comprising: (a) 10-40% by weight based on the active ingredients of behenyl alcohol; (b) 1.0-8.0% by weight of an anionic surfactant selected from the group consisting of sodium lauryl ether sulfate, sodium lauryl sulfate, magnesium lauryl ether sulfate, magnesium lauryl sulfate , calcium lauryl ether sulfate, calcium lauryl sulfate, ammonium lauryl ether sulfate and ammonium lauryl sulfate; and (c) 1.0-3.0% by weight (based on assets) of a betaine selected from the group consisting of C12-18 amidopropyl betaines; wherein the dispersion has a stability of at least 3 months at a temperature of 49 degrees C, a viscosity in the range of 1,000-20,000 centipoise and no more than 0.2% by weight of a cationic material. Process to make dispersion. |
