Abstract

An aqueous suspension of cross-linked silicone particles comprising (A) cross-linked silicone particles having an average diameter of 0.1 to 500 μm, (B) polyoxyethylene sorbitan monolaurate, and (C) water. And, in a second embodiment, an aqueous emulsion of cross-linked silicone particles comprising (A) cross-linked silicone particles having an average diameter of 0.1 to 500 μm, (B) polyoxyethylene sorbitan monolaurate, (C) water, and (D) oil.

Claims (18)

1. An aqueous emulsion of cross-linked silicone particles comprising (A) cross-linked silicone particles having an average diameter from 0.1 to 500 μm, (B) polyoxyethylene sorbitan monolaurate, (C) water, (E) oil, and (D), phenoxyethanol described by the general formula

wherein R is selected from the group consisting of (i) a hydrogen atom and (ii) a methyl group and n is an integer from 1 to 10.

2. The emulsion of claim 1 comprising component (A) in drops of component (E) dispersed in water.

3. The aqueous emulsion of claim 1 having an addition mole number of ethylene oxide of component (B) of 10 to 25.

4. The aqueous emulsion of claim 1 having an addition mole number of ethylene oxide of component (B) of 18 to 22.

5. The aqueous emulsion of claim 1 , where the HLB of component (B) is at least 10.

6. The aqueous emulsion of claim 1 , where R is a hydrogen atom and n is 1.

7. The aqueous emulsion of claim 1 , where the cross-linked silicone particles (A) have an average diameter of 0.1 to 50 μm.

8. The aqueous emulsion of claim 1 , comprising 0.01 to 10 wt. % of component (B).

9. An aqueous suspension of cross-linked silicone particles comprising (A) cross-linked silicone particles having an average diameter of 0.1 to 500 μm, (B) polyoxyethylene sorbitan monolaurate, (C) water, and (D) phenoxyethanol described by the general formula

where R is selected from the group consisting of (i) a hydrogen atom and (ii) a methyl group and n is an integer from 1 to 10.

10. The aqueous suspension of claim 9 , wherein component (A) comprises cross-linked silicone particles containing non-cross-linked silicone oil.

11. The aqueous suspension of claim 9 , having an addition mole number of ethylene oxide of component (B) of 10 to 25.

12. The aqueous suspension of claim 9 , having an addition mole number of ethylene oxide of component (B) of 18 to 22.

13. The aqueous suspension of claim 9 , where component (B) has an HLB of at least 10.

14. The aqueous suspension of claim 9 , where the cross-linked silicone particles (A) have an average diameter of 0.1 to 50 μm.

15. The aqueous suspension of claim 9 , comprising 0.01 to 10 wt.% of component (B).

16. The aqueous suspension of claim 9 , where R is hydrogen and n is 1.
