2.1. The problem addressed by the present invention is that of providing silicic acids which are highly hydrophobic and therefore can be used with particular success to control the rheological or triboelectric properties of liquid media or as flow enhancers. 2.2. The problem is solved by providing silicic acids which are surface-modified with a compound from the group (RO) 3 SiR', wherein R' = C n H 2 (n-m)+1 , n = 9 to 14, m = 0 to n and R = C q H 2q+1 , where q = 1 to 4. Also described is a method for the surface modification of silicic acids, which are treated in a thermal reaction with a modification agent selected from one or more organotrialkoxysilanes of general formula (RO) 3 SiR', wherein R' = C n H 2 (n-m)+1 , where n = 9 to 14 and m = 0 to n and R = C q H 2q+1 , where q = 1 to 4. 2.3. The silicic acids surface-modified according to the invention can be used to control the rheological or triboelectric properties of liquid media, such as, for example, as thickeners and antiblocking agents, or as flow enhancers.

The invention relates to agrochemical compositions comprising oils and alkylpolysiloxanes of high silicone character (HSCAS) with good oil compatibility which improve the spreading behavior and reduce surface tension of oil-based agricultural formulations, and optionally comprising agrochemically active ingredients such as fungicides, insecticides or herbicides and/or inert ingredients such as emulsifiers and other agrochemically acceptable components.
摘要:
A dispersant of the present invention is used after being added to a dispersant obtained by dispersing fine particles of a crystalline polymer as a dispersed particle and is characterized by containing a copolymer of a first monomer and a second monomer, the first monomer being a monomer that can be crystallized as a polymer having the molecular structure identical to that of the dispersed particle.

The present invention relates to a method for improving the storage stability of aqueous composite-particle dispersions and to aqueous formulations containing said aqueous composite-particle dispersions.
摘要:
The invention relates to oil-in-water emulsions, methods of making said emulsions and their uses in fabric care or hair care compositions. The fabric care composition comprises a silicone oil-in-water emulsion which emulsion is obtained by a. forming an oil phase by mixing at least one silicone compound with at least one silicone-free oil, b. optionally adding an emulsifier, c. adding water, d. forming an oil-in-water emulsion. A silicone oil, comprising a siloxane or polysiloxane compound, for example polydimethyl siloxane (polydimethyl silicone or PDMS), or a derivative thereof, e.g., amino and amido silicone, diluted with a silicone-free oil still can provide an emulsion providing high fabric care properties while decreasing the costs.
