1. An aqueous hair or skin conditioner composition comprising a compound of formula (I)

OG Complex Work Unit Drawing
wherein
a and b represent ethylene oxide and propylene oxide repeat units, respectively;
n is 1-4; and
wherein the ethylene oxide repeat units are 17, 27, or 37 wt. % of the sum of the ethylene oxide and propylene oxide repeat units; and
wherein
the aqueous composition comprises from about 0.05 to about 10 wt. % of the compound of formula (I) and from about 10 to about 95 wt. % water, based on the total weight of the composition; and
the compound of formula (I) has a weight average molecular weight of 8,000, a cloud point of from about 18-20° C. and an HLB from 1 to 7;
wherein the cloud point is determined by mixing 1 g of formula (I) in 50 g of deionized water, followed by cooling the mixture to a temperature of 5° C. and gradually raising the temperature until the cloud point is reached.
