  • Publication number: 20090304618
    Abstract: The presently described technology relates to acyl lactylate containing compositions having improved stability and multifunctional performance characteristics (e.g., pH stability, phase stability, hydrolytic stability (e.g., aqueous stability), cleansing, foaming, skin softness and skin moisturization) that may be utilized in rinse-out and leave-on skin and hair applications. The acyl lactylate compositions of the present technology may be delivered to the skin or hair via a conventional delivery vehicle such as a body wash, a shampoo, a bubble bath, a skin cream, or a lotion.

  • Publication number: 20090200511
    Abstract: Provided are alkyl lactyllactate compositions that can be prepared from (1) lactide or alternatively lactic acid, and (2) a hydroxyl containing compound such as an alcohol, preferably a fatty alcohol or an alkoxylated alcohol, with (3) an acid catalyst. Preferably, the fatty alcohol contains from about 6 to 18 carbon atoms, such as lauryl alcohol. The alkyl lactyllactates can be used as surfactants, emulsifiers, skin feel agents, film formers, thickeners, rheological modifiers, etc., for personal care and other application areas. Compositions containing at least one alkyl lactyllactate are also provided. The compositions can further contain at least one surfactant.

  • Patent number: 6423326
    Abstract: The present invention relates to stable cold-mix water-in-oil emulsions and methods for preparing such emulsions. The cold-mix water-in-oil emulsions comprise oil (i.e., an emollient), water and an emulsification system comprising a quaternary ammonium-based low HLB emulsifier and optional co-emulsifiers. The emulsions are useful in preparing finished cosmetic compositions in the form of lotions, gels, or sprays, which provide improved moisturization, skin feel, skin care, and/or appearance benefits and/or reduced greasiness, with excellent rub-in and absorption characteristics. Also disclosed are cold-mix water-in-oil sunscreen emulsions and methods for preparing such sunscreen emulsions. The emulsions of the instant invention are generally capable of being substantially completely emulsified and stable at about 25° C.
