Abstract
An organopolysiloxane gum emulsion is afforded by the emulsification of an organopolysiloxane gum in water. The organopolysiloxane gum emulsion is useful as a cosmetic base, lustrant, lubricant, antifoam, fiber-treatment agent, and paint additive. The organopolysiloxane gum emulsion includes (A) 100 weight parts organopolysiloxane gum whose plasticity at 25.degree. C. is at least 0.75 mm, (B) 1 to 100 weight parts emulsifying agent, and (C) 3 to 800 weight parts water.
Claims12
An emulsion comprising (A) 100 parts by weight of an organopolysiloxane gum with a plasticity value at 25.degree. C. of at least 0.75 mm, the value being determined according to Japanese Industrial Standard JIS C 2123-1986;
- (B) 1-100 parts by weight of an emulsifying agent per 100 parts by weight of the gum;
- and (C) 3-800 parts by weight of water per 100 parts by weight of the gum;
- the emulsion being made by emulsifying the gum in water with the emulsifying agent, with the proviso that at least 11 percent of the gum is present in the emulsion.
An emulsion comprising (A) 100 parts by weight of an organopolysiloxane gum with a plasticity value at 25.degree. C. of 1-2.5 mm, the value being determined according to Japanese Industrial Standard JIS C 2123-1986(B) 1-100 parts by weight of an emulsifying agent per 100 parts by weight of the gum;
- and (C) 3-800 parts by weight of water per 100 parts by weight of the gum;
- the emulsion being made by emulsifying the gum in water with the emulsifying agent, with the proviso that at least 15 percent of the gum is present in the emulsion.
