摘要:
The present invention relates to a method of cleaning fabrics in washing machines which have parts made of natural rubber using laundry detergents comprising N-acyl caprolactam bleaching activators and a source of hydrogen peroxide such that said natural rubber parts of said machines are substantially undamaged by free radical by-products of the perhydrolysis reaction between the activator and hydrogen peroxide.

摘要:
The present invention provides nonionic surfactant systems comprising: (a) one or more polyhydroxy fatty acid amides having formula (I), wherein R1 is H, a C¿1?-C4 hydrocarbyl, 2-hydroxy ethyl, 2-hydroxy propyl, or mixtures thereof, R?2¿ is a C¿5?-C31 hydrocarbyl, and Z is a polyhydroxyhydrocarbyl having a linear hydrocarbyl chain with at least three hydroxyl groups directly connected to the chain, or an alkoxylated derivative thereof; and (b) one or more additional nonionic surfactants; wherein the weight ratio of polyhydroxy fatty acid amide (a) to additional nonionic surfactant (b) is in the range of from about 1:5 to about 5:1. The present invention also provides laundry detergent compositions which contain the nonionic surfactant systems described above. When included in such laundry detergent compositions, these nonionic surfactant systems unexepctedly improve the stain removal performance of such compositions against greasy/oily stains across a broad range of laundry conditions. This invention further provides a method for improving the stain-removing performance of detergent compositions by incorporating into such compositions the nonionic surfactant systems described above.
摘要:
Compositions for treating fabric articles, especially articles of clothing, linens and drapery, wherein the compositions provide improved cleaning of soils from and/or care of and/or treatment of fabric articles, especially while providing superior garment care for articles sensitive to water as compared to conventional fabric article treating compositions, are provided.

The present invention relates to a method of cleaning fabrics with heavy soil loads or by hand-washing with detergent compositions comprising N-acyl caprolactam bleaching activators.
摘要:
Systèmes tensioactifs non ioniques comprenant: (a) un ou plusieurs amides d'acides gras de polyhydroxy de formule (I), dans laquelle R1 est H, un hydrocarbyle C1-C4, 2-hydroxy éthyle, 2-hydroxy propyle, ou des mélanges de ces composés, R2 est un hydrocarbyle C5-C31, et Z est un polyhydroxy hydrocarbyle possédant une chaîne hydrocarbyle linéaire présentant au moins trois groupes hydroxyle reliés directement à la chaîne, ou un dérivé alcoxylé de ce composé; et (b) un ou plusieurs tensioactifs non ioniques supplémentaires. Le rapport pondéral entre l'amide d'acide gras polyhydroxy (a) et le tensioactif non ionique supplémentaire (b) se situe entre environ 1:5 et environ 5:1. La présente invention permet également de produire des compositions détergentes contenant les systèmes tensioactifs non ioniques susmentionnées. Lorsqu'ils sont inclus dans des compositions détergentes pour lessive, ces systèmes tensioactifs non ioniques améliorent de manière inattendue le pouvoir détachant desdites compositions et permettent de traiter des taches d'huile ou de graisse dans une vaste gamme de conditions de lessive. Est également décrit un procédé permettant d'accroître le pouvoir détachant des compositions détergentes par l'incorporation dans ces compositions des systèmes tensioactifs non ioniques susmentionnés.
