  The invention relates to metal working fluids being oil-in-water emulsions comprising alkylated polyvinylpyrrolidones as surfactants for emulsifying the oil in water. Said alkylated polyvinylpyrrolidones having a molecular weight of about 5,000 up to 20,000 provide emulsions showing a high emulsion stability under varying and severe processing conditions of metal working fluids. Other advantages of the metal working fluids according to the invention are the narrow distribution of the droplet size, the high stability against varying quality/composition of the make-up water, a high capacity of dispensing metal fines in the metal working fluid as well as excellent film forming characteristics.

  本发明涉及水包油型乳液金属加工液，该乳液含有烷基化聚乙烯吡咯烷酮作为表面活性剂，用于乳化水包油。所述烷基化聚乙烯吡咯烷酮的分子量约为 5,000 到 20,000 之间，可提供在金属加工液的不同和苛刻加工条件下显示出高乳化稳定性的乳液。本发明金属加工液的其他优点还包括：液滴粒径分布窄、对不同质量/成分的补给水具有高稳定性、在金属加工液中具有较高的金属细粒分配能力以及出色的成膜特性。

  Skin care, hair care and hair coloring compositions comprising a water-soluble silk protein as an active ingredient are described. The water-soluble silk protein deposits onto the skin or the natural hair keratin to provide a smooth and durable film to provide added strength for protection against environmental, chemical, and grooming associated damage. The compositions may be in the form of skin care, skin cleansing, or anti-wrinkle products, shampoos, conditioners, lotions, aerosols, gels, mousses, dyes, or bleaches.
