Cold pearlizing concentrates are described which provide pearlescence to personal care and beauty care products, such as shampoos and beauty soaps, giving added luster and sheen. The pearlizing agent consists essentially of a fatty acid based member selected from the group consisting of hydroxyl stearate, polyethylene glycol mono- and di-stearates, ethylene glycol mono- and di-stearates, stearic monoethanolamide, and mixtures thereof, wherein at least about 90 % by weight of the fatty acids of said fatty acid based member consists of octadecanoic acid. The pearlizing agent has high temperature stability and is stable in shampoos which also contain a silicone emulsion, even at temperatures as high as 65 ~C.
