Abstract

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.
