Abstract
The present invention relates to an aqueous emulsion of peroxyester, comprising at least one peroxyester, at least one antifreeze and a combination of at least two emulsifiers chosen from the group consisting of a non-ethoxylated sorbitan ester, an ethoxylated sorbitan ester and an ethoxylated fatty alcohol.
Claims20
An aqueous emulsion of organic peroxide, consisting of:
- at least one peroxyester,
- at least one antifreeze,
- a combination of at least two emulsifiers selected from the group consisting of:
- a non-ethoxylated sorbitan ester,
- an ethoxylated sorbitan ester, and
- an ethoxylated fatty alcohol,
- optionally, one or more additives in a content between 10 ppm and 10,000 ppm by weight relative to the weight of the emulsion, and
- water,
- wherein the antifreeze comprises ethanol in combination with another alcohol selected from ethylene glycol, 1,2-propanediol, 1,3-propanediol, glycerol, 1,3-butanediol, 1,4-butanediol, and mixtures thereof.
