  • Permanent waving compositions containing fatty acid lactylates and glycolates and their method of use
    Patent number: 4301820
    Abstract: Fatty acid lactylates and/or glycolates are combined as humectant compounds with at least one reducing agent for hair and used in a permanent waving operation. In comparison to hair permanently waved without their use, the humectant compounds impart increased moisture retention to the hair without sacrificing waving efficiency while, in most instances, showing improved waving efficiencies, particularly at elevated humidities.
