Assembly containing at least one dyeing substrate and at least one protective substrate comprising one or more preservatives, dispensing means, and dyeing process The present invention relates to the field of dyeing keratin fibres and more particularly to the field of hair dyeing. The present invention relates to an assembly 2 containing at least one dyeing substrate 3, and at least one protective substrate 4a, 4b comprising one or more preservatives, and it being understood that the dyeing substrate(s) 3 are different from the protective substrate(s) 4a, 4b. The present invention also relates to a means for dispensing 1 the assembly 2, and also to a process for dyeing keratin fibres using said assembly 2.

The present invention relates to the synthesis of new classes of sunscreen agents, the usage of such sunscreen agents to prepare sunscreen formulation materials aiming at reduction of sunscreen agents’ skin penetration. The whole purpose of this invention is to improve the biosafety of sunscreen products via our novel sunscreen materials and formulation technology to reduce or to eliminate skin penetration of sunscreen agents. The technology of this invention can be applied to cosmetics, pharmaceutical or insects’ repellant products.

The present disclosure relates to a developer composition comprising one or more direct dyes having at least one halogenated aromatic group, one or more oxidizing agents, and water; wherein the pH of the developer composition is from about 1 to about 4. The developer compositions are combined with hair coloring base compositions to form ready-to-use hair coloring compositions. Methods for making ready to use hair coloring compositions and methods for coloring hair are also disclosed.

The subject of the present application is an agent for the oxidative dyeing of keratinous fibers, in particular human hair, which contains the coupling oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol in combination with the oxidation base 2-methoxymethyl-para-phenylenediamine.

The present invention is in the field of personal care compositions, in particular compositions comprising antiperspirant actives. The present invention more particularly relates to compositions containing zinc based actives, yet exhibit good efficacy. This is achieved through use of an active which is a complex of a zinc salt with a β amino acid, in an anhydrous solvent comprising an alcohol, along with a multivalent metal salt.

A dye composition I, comprises: a) at least one oxidative dye(s), b) at least one thickener selected from anionic polymer(s), and c) at least one antioxidant including thiol-derived reducer(s). A kit comprises (1) the dye composition I and (2) oxidizing composition IL, comprising at least one oxidant.

The invention relates to primary para-phenylenediamine compounds substituted with an aliphatic chain comprising a cationic heterocyclic group according to formula (I), as well as the organic or mineral acid or base addition salts thereof, optical isomers, geometric isomers, tautomers, mesomers and/or solvates thereof, such as hydrates. Formula (I), wherein: ALK is a linear or branched, optionally substituted, alkylene chain comprising 3 to 8 carbon atoms; HET.sup.+ is a saturated or unsaturated, aromatic or non-aromatic cationic heterocyclic group, optionally substituted, comprising 5 to 0 links, optionally substituted, and comprising one or more ammonium groups; and An.sup.−, present or absent, is a mineral or organic anionic counterion ensuring the electroneutrality of the molecule. The present invention also relates to a composition comprising one or more of these previously defined compounds, in a medium suitable for dyeing. The present invention lastly relates to a dyeing device consisting of a first compartment which contains said composition, and a second compartment containing one or more oxidising agents.
