Abstract: A sprayer with a water purifier, a valve system, and a selector switch for the same are disclosed. In one non-limiting embodiment, when the sprayer is in use, the sprayer includes a purifier for purifying water. The sprayer may be compact and ergonomic. The sprayer may include a valve system that provides a selection of water flow paths and/or nozzles or other output mechanisms for the sprayer, and a selector switch for controlling the valve system. In certain embodiments, the sprayer is provided with a multiple position selector switch that can be controlled by one of the operator's fingers, or by the operator's thumb so that the operator can use the sprayer and select the sprayer setting with one hand.

Abstract: The present invention relates to hair care compositions comprising an oxidizing agent and chelants having log ? ? K CuL log ? ? K CaL 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).

Abstract: Primary intermediates for hair coloring compositions for oxidative dyeing of hair are compounds of the formula (1): wherein R1 and R2 are each independently selected from hydrogen atoms, a C1 to C5 alkyl or hydroxyalkyl group, or R1 and R2 together with the nitrogen atom to which they are attached form a 5 or 6 member cyclic ring optionally containing one or more additional atoms selected from O, N or S atoms, and n is equal to 1 or 2, with the proviso that when n is equal to 2 only one of R1 and R2 may be hydrogen.
Abstract: The present invention provides a hair coloring composition comprising (iv) at least one developer selected from amino aromatic systems capable of being oxidised and thereafter undergoing only a single electrophilic attack reaction, and (v) at least one developer selected from amino aromatic systems capable of being oxidised and thereafter undergoing at least two electrophilic attack reactions, and (vi) at least one coupler, which delivers improved root-to-tip evenness and improved hair color.

Abstract: Disclosed are oxidative hair dye compositions containing polyalkyleneglycol(n)alkylamine and a solid fatty compound. One embodiment of the present invention is, for example, an oxidative hair dye composition comprising a first component and a second component wherein said first component comprises at least one oxidative dye or mixture thereof, a polyalkyleneglycol(n)alkylamine of the formula (I): wherein each R is independently a saturated, unsaturated, straight or branched alkyl group having from 1 to about 30 carbon atoms, each m is 2 or 3, each n is 2 or 3, each x and each y are independently a number of 1 or more wherein the sum of each x and each y is from about 2 to about 9; and wherein the melting point of the polyalkyleneglycol(n)alkylamine is less than about 55° C.; a solid fatty compound; and water and wherein said second component comprises at least one oxidising agent and wherein the viscosity of said first and said second component are independently from greater than 1.0 Pas to 20 Pas.

Abstract: Disclosed are topical leave-on cosmetic compositions, including packaged leave-on compositions, for direct application to the scalp, comprising a) from about 40% to about 99% by weight of a volatile liquid, b) from about 0.005% to about 20% by weight of a skin active agent, and c) from about 0.1% to about 20% by weight of a moisturizing material, preferably a liquid humectant. The composition is a leave-on formulation that is substantially free of cleansing surfactants and is applied directly to the scalp. Also disclosed are methods of treating the scalp by directly applying the topical composition to the scalp. It has been found that the compositions and methods of the present invention can provide improved scalp moisturization and improved deposition of an anti-dandruff or other skin active agent on the skin, without unduly affecting hair cosmetics.
