A coalescent composition selected from 1,3-(C6-C12alkyloxy)-2-propanol, 1,1'-oxybis[3-(C6-C12alkyloxy)]-2-propanol, and mixtures thereof is provided. Preferred coalescents are 1,3-(decyloxy)-2-propanol and 1,1'-oxybis[3-(heptyloxy)]-2-propanol. A method for forming glycerol diethers and diglycerol diethers, an aqueous coating composition including the coalescent compositions and a method for forming a coating are also provided.

Provided are: a novel polyglycerol di-(alkyl/alkenyl) ether that is useful as a highly hydrophilic gemini surfactant; and a cosmetic composition containing the polyglycerol di-(alkyl/alkenyl) ether. The polyglycerol di-(alkyl/alkenyl) ether is represented by Formula (1), where R1 and R2 are identical or different and are independently a straight- or branched-chain alkyl group or a straight- or branched-chain alkenyl group, where the alkyl group may have one or more hydroxyl groups; and n indicates a number of glycerol units and is an integer of 2 or more. Formula (1) is expressed as follows:
Novel phospholipids, inclusive of salts thereof, of the formula
wherein
R1 and R2 are independently an aliphatic hydrocarbon residue containing 1 to 20 carbon atoms, with the numbers of the carbon atoms for both totalling 8 to 30, and
R3, R4 and R5 are independently hydrogen or C1-6 alkyl, or
represents a cyclic ammonio group, exhibitory activity against the multiplication of tumor cells and antifungal activity.
