Abstract
Diethylmethylammonionitriles of the formula (1) in which A is an anion are claimed. These compounds are suitable as a bleach activator in washing and cleaning compositions.
Claims
exact text as granted — not AI-modified1 . A diethylmethylammonionitrile of the formula (1)
in which A is selected from the group consisting of chloride, bromide, sulfate, hydrogensulfate, methosulfonate, ethanesulfonate, toluenesulfonate, benzenesulfonate, and cumenesulfonate.
2 . A washing and cleaning composition comprising a compound of the formula 2
in which A is an anion.
3 . The washing and cleaning composition of claim 2 , wherein the compound of the formula 2 is present in the form of a granule.
4 . A process for bleaching colored stains on a textile and a hard surface, said process comprising contacting the textile or the hard surface with a solution comprising the diethylammonionitriles of the formula (2)
wherein A is an anion together with a peroxygen compound.
5 . The process of claim 4 , wherein the process is carried out at a bleaching temperature between 40 and 60° C.Cited by (0)
