Multi-component package unit (kit-of-parts), ready-to-use agent, and methods for reductive decolorizing of dyed keratinous fibers are provided herein. In an embodiment, a multi-component package unit includes, separately packaged, a first container (A), a second container (B), and a third container (C). The first container (A) includes a cosmetic agent (a) that includes (a1) one or multiple reducing agents chosen from the group of formamidine sulfinic acid, sodium dithionite, zinc dithionite, potassium dithionite, hydroxymethanesulfinic acid, aminomethanesulfinic acid, cysteine, thiolactic acid, sulphanylacetic acid (thioglycolic acid) and/or ascorbic acid. The second container (B) includes a cosmetic agent (b) that includes one or multiple oxidizing agents. The third container (C) includes a cosmetic agent (c) that includes (c1) one or multiple alkalizing agents. The weight ratio of the total amount of all reducing agents (a1) to the total amount of all oxidants (b1) has a value from about 50.0 to about 4.0.

Disclosed are methods of grafting monomeric and polymeric materials on keratin-containing material to provide a covalent coating on keratin-containing material. A mixture comprising a reducing agent is applied to the keratin-containing material sample. The keratin-containing material sample then comprises a plurality of free thiol groups. A monomer is applied to the keratin-containing material sample. The free thiol groups react with the monomer to form a plurality of covalent bonds between the free thiol groups and the monomers. The reducing agent and the monomer can be applied separately, semi-simultaneously, or simultaneously. The disclosed methods can be carried out with or without catalyst. The disclosed methods can be carried out with or without an additive.

Disclosed are dermatological or cosmetic cream, serum and toner compositions and methods thereof for use in promoting healthy skin. A dermatological composition (cream, toner and serum) is applied to the skin to promote optimal health of the skin. The preferred cream composition is comprised of, reduced glutathione and/or cysteinylglycine, ascorbyl glucoside in a dermatologically acceptable carrier containing a salt composition. Preferably, the salt composition contains sodium, magnesium, potassium and calcium. The cream formulations are optionally ionically balanced. Preferably, potassium chloride, magnesium chloride, calcium chloride, magnesium sulfate and potassium phosphate are present in sufficient amounts. Toner composition contains sodium, magnesium, potassium and calcium ions and optionally bicarbonate ions and preservative(s). The toner formulations are optionally ionically balanced. The preferred serum composition contains ascorbyl glucoside and/or ascorbic acid in a carrier. Methods of manufacture of these compositions are also disclosed.

The invention relates to compositions comprising hydrophobically and non-hydrophobially modified cross-linked anionic polymers which have been found to minimally hinder deposition of moisturizers in compositions comprising cationic deposition polymers.

The present invention relates to a detergent containing or prepared by blending: (A) at least one selected from the group consisting of an alkyl sultaine, an alkyl hydroxysultaine, and a nonionic surfactant; and (B) an aminopolyether-modified silicone containing a polyoxyalkylene structure and satisfying the following formula (I):

0.01≤Si/AO≤1.6  (I)

[in the formula (I), Si represents a molar number of a silicon atom in the component (B), and AO represents an oxyalkylene average addition molar number in the component (B)], wherein a mass ratio [(A)/(B)] of the component (A) to the component (B) is 0.1 or more and 1,000 or less.

A keratin hydrolysate including at least 88% by weight of free amino acids relative to the total weight of the amino acids of the hydrolysate, the remainder of the hydrolysate being peptides having a molecular mass of less than or equal to 800 Dalton, the hydrolysate also including L-cystine in a content ranging from 4% to 6%, cysteine in a content of less than or equal to 0.1%, and tyrosine in a content of less than or equal to 0.6% by weight, relative to the total weight of the hydrolysate. Also, a process for preparing the hydrolysate, the oral cosmetic use of the hydrolysate for improving the appearance of the nails and/or of the hair, and a dietary supplement including the hydrolysate and optionally vitamins, zinc and/or L-cystine.

The present disclosure provides compositions which may be used to augment, supplement and/or replace the products of certain UV sensitive/dependent processes. In particular, the disclosure provides sunscreen compositions which avoid problems associated with prior art sunscreen compositions which inhibit the natural progression of certain in vivo sunlight/UV dependent processes including processes which result in Nitric Oxide/Vitamin D production in the skin.

A method of repairing oxidatively-treated hair, the methods comprising the sequential steps of: (i) soaking hair in an aqueous treatment composition, (ii) rinsing the hair of step (i); characterised in that the aqueous treatment composition comprises 0.1 to 6 wt % N-acetyl amino acid, based on the total weight of the composition, wherein the N-acetyl amino acid is selected from the group consisting of N-acetyl glycine, N-acetyl alanine, N-acetyl proline, N-acetyl leucine, N-acetyl isoleucine, N-acetyl valine, N-acetyl tyrosine, N-acetyl phenylalanine, N-acetyl tryptophan, N-acetyl serine, N-acetyl glutamine, N-acetyl threonine, N-acetyl asparagine, N-acetyl methionine, N-acetyl lysine, N-acetyl histidine and mixtures thereof, gives damage repair benefits.
