摘要:
The present invention relates to hair care compositions comprising an oxidizing agent and chelants having a log KCuL/log KCaL ratio calculated at pH 10 of at least 3.20 wherein log KCuL is the common logarithm of the Conditional Stability Constant of said chelant with Cu2+ and log KCaL is the common logarithm of the Conditional Stability Constant of said chelant with Ca2+. Suitable chelants are diamine-N,N′-dipolyacids or monoamine monoamide-N,N′-dipolyacids. The compositions according to the present invention contribute to reducing the oxidative damage sustained by a keratinous fiber such as hair during bleaching, dyeing, perming or other oxidative treatments. Especially preferred diamine dipolyacid is ethylenediamine-N,N′-disuccinic acid (EDDS).

摘要:
The present invention relates to hair care compositions comprising chelants and methods for reducing oxidative hair damage. The compositions contribute to reducing the oxidative damage sustained by keratinous fibers such as human hair during bleaching, dyeing, perming or other oxidative treatments. The compositions according to the present invention also provide excellent color evenness and color fastness.
摘要:
A laminate structure for use as a container for liquids including a structural substrate such as a paperboard which facilitates a gable top container having incorporated on its inner surface a layer of a fibrous matrix which has encapsulated or incorporated therein a finely ground divinylbenzene ethyl vinylbenzene copolymer, polystyrene divinylbenzene copolymer resin or a cyclodextrin placed on its inner surface. Additionally, the fibrous matrix may be produced as an insert and attached to the inner surface of the gable top container through the use of various items such as hot melt adhesives.
