Boake, Roberts & Co. Ltd. Method Heat the oils and waxes together to a temperature of about 75 ø C. When the waxes have melted entirely, slowly add a solution of the preserva- tive in the water (also at a temperature of about 75 ø C.) and stir thoroughly until a uniform cream is produced. Cool, and incorporate the perfume. Allow to stand overnight, and stir again for about 20 minutes. (b) HAIR CREAMS The non-greasiness of acetoglycerides is also of particular advantage when considering the formulation of hair creams, and the formula given below is for an inexpensive dressing which, by the incorporation of an acetoglyceride in place of part of the oil which would otherwise be used, is rendered virtually non-staining.

CHEMISTRY OF ACETOGLYCERIDES AND THEIR USES IN COSMETICS 51 Method Heat a solution of the preservative in water to a temperature of about 80 ø C. and add it, with rapid stirring, to a mixture of the oils and waxes-- also heated to the same temperature. Continue stirring until the tempera- ture has dropped to about 35-40 ø C. add the pertume, and homogenise the crearrf. (c) SHaYINC CREAMS For preparations such as shaving creams, liquid acetoglycerides are recommended as, apart from improving the appearance and feel of the product, they leave the skin softer after shaving. (Acetoglycerides are not normally used as replacements for glycerol.) A shaving cream prepared in accordance with the formula given below dried only very slightly on the face, and gave an effective soft feel to the skin, leaving the latter entirely free from soreness.

Method Dissolve the triethanolamine, glycerol, ca ustic potash and preservative in the water (part B), and heat to a'temperature of about 75 ø C. Mix together the constituents of part A, and heat these also to the same temperature. When a uniform mixture has been obtained, add part B to part A an d stir thoroughly until an even cream is produced. Cool, and incorporate the perfume. Allow to stand overnight, and stir again for about 20 minutes. (d) ANTI-SUNBURN CREAMS AND LOTIONS Acetoglycerides are of particular interest for the formulation of creams and lotions which yield a continuous non-greasy film. (e) HaND CREAMS aNI) LOTIONS In hand creams and lotions, acetoglycerides are of special value as they can be used in the formulation of non-greasy products which have a desirable emollient and softening effect on the skin.
