USE OF POLYOXYALKYLENE/POLYSILOXANE COPOLYMER AS EMULSIFIER FOR PRODUCING WATER/OIL TYPE EMULSION
The invention relates to the use of copolymers of the average formula +TR in which R is an alkyl radical with 1 to 4 carbon atoms or a hydrogen radical; n=10 to 200; m=1 to 25; o=1 to 100 with the proviso that o is not less than m, and 3 o is less than n in the average molecule; p=7 to 17; and where...

Zusammenfassung: | The invention relates to the use of copolymers of the average formula +TR in which R is an alkyl radical with 1 to 4 carbon atoms or a hydrogen radical; n=10 to 200; m=1 to 25; o=1 to 100 with the proviso that o is not less than m, and 3 o is less than n in the average molecule; p=7 to 17; and wherein the molecular weight of the (C2H4O-)x(C3H6O-)yR radical is 250 to 2,000 with x and y being selected so that the weight ratio of oxyethylene to oxypropylene is 100:0 to 20:80, as emulsifiers for the preparation of W/O emulsions, whose oily phase consists of or contains silicone oil. |
