    摘要: The invention relates to a process for preparing silanes or siloxanes having carboxyl functionalities, wherein a hydrogen silane or hydrogen siloxane compound is reacted with a tertiary butyl ester having an olefinic double bond and the sil(ox) ane-bonded tertiary butyl ester group is subsequently converted into the corresponding carboxyl group with elimination of isobutene.

    摘要: This invention relates to asymmetrical, substituted polysiloxanes which show good compatibility in a variety of oils and improve the spreading behavior of oil-based formulations, to a process for preparing these asymmetrical polysiloxanes and to oil formulations containing said asymmetrical polysiloxanes. The asymmetrical polysiloxanes of this invention are used in herbicidal and pesticidal compositions, in cosmetic and pharmaceutical preparations as well as in industrial applications. The assymmetrical substituted polysiloxanes have the following formula wherein R1, R2, Z a and b are described herein.

    摘要: The invention discloses skin treatment compositions consisting essentially of a mixture of ceramides, cholesterol, free fatty acids—the mixture being able to mimic skin identical lamellar structures—and nonionic emulsifiers. These compositions are liquid and pumpable at room temperature which means that they can be incorporated easily into cosmetic formulations with no need for heating. Furthermore, the skin treatment compositions allow the stable inclusion of long-chain ceramides into oil-in-water emulsions as well as into water-in-oil emulsions. Inclusion of short chain ceramides that can act as dermatological regulators did not affect the lamellar lipid organization. The skin treatment compositions are claimed as well as their use in cosmetic and dermatological formulations.
