Abstract
The article analyzes the properties of wild rose and black current oils, received from wastages of fruit and berry processing. Oils from secondary materials are usually used as food and processing additives. We suggest their utilization as functional additives to cosmetic soap. Functional properties of oils are conditioned by fatty acid composition, which was determined with Gas Chromatography. It has been noted that both types of oil contain linoleic, oleate, alpha-linolenic acid, and some medium-chain-length fatty acids. Besides, black currant oil has high content of hamma-linolenic acid. The recommended dosage of additives has been determined with the account of interaction with other components of soap by Delphi method. The best ratio is 1.5...2.0 % of wild rose or black currant oils to the mass of the soap base.
