The present disclosure provides at least one skin supplement composition that has been shown to be advantageous for healthy skin, preferably comprised of hydrolyzed collagen, glucosamine sulfate, biotin, vitamin A palmitate, vitamin E, alpha lipoic acid, coenzyme Q.sub.10, pine bark extract, L-selenomethionone and niacinamide. An advantageous nootropic composition is also disclosed preferably comprised of ascorbic acid, taurine, elemental magnesium, glycinate, L-theanine, L-tyrosine, pine bark extract, N-acetyl-L-carnitine, DL-choline bitartrate, maca root, glucosinolates, P5P (pyridoxal-5-phosphate) and alpha ketoglutaric acid. A method to provide a specifically tailored supplement is also disclosed, preferably of collecting dry blood spots, analyzing the dry blood spots with tandem mass spectrometry, determining an amino acid kinetic pattern based on the analysis, and generating the specifically tailor supplement based on the pattern.

The present invention is a versatile cosmetic composition in form of a liquid concentrate which is useful as additive or ingredient for conventional keratin fiber treatment compositions. It can be used as ready to use additive to conventional yet damaging treatments to which it is added at the time of the treatment. Such treatments are typically hair bleaches, hair colorants or permanent wave compositions. The concentrate comprises a combination of ingredients intended to reduce damage during treatments and/or to prevent undesired deposits on fibers. Such a composition comprises at least a thiol and a polymer or copolymer comprising cystine units. Such a composition is further useful as additive or ingredient for a keratin fiber caring or repairing composition to reduce damage caused by prior treatments and/or reduce undesired deposits on fibers by using the concentrate directly after treatments causing such deposits.

A multicomponent packaging unit (kit of parts) for permanently changing the shape of keratinic fibers, in particular human hair, comprises the following packaged separately from one another: a container (i) containing a cosmetic agent (A), and a container (ii) containing a cosmetic agent (B),
where agent (A) in container (i) contains at least one keratin-reducing compound, and agent (B) in container (ii) contains at least one compound of general formula (I)

##STR00001##

Also provides a method of using the kit and of using Bunte salts of formula (I) on hair.

The present disclosure relates to color-altering compositions. The compositions comprise a hair color-altering agent and at least one carboxylic acid. Certain compositions further comprise at least one amino acid or amino sulfonic acid, and/or a salt thereof selected from the group consisting of taurine, aspartic acid, cysteine, lysine, methionine, tyrosine, phenylalanine, carnitine, a salt thereof, and a mixture thereof. Also provided are kits and methods of using said color-altering compositions.

A shampoo composition is disclosed that has from about 5 to about 40 weight % of one or more detersive surfactants and an aqueous carrier comprising water and one or more polyols, wherein the weight ratio of one or more polyols to water is higher than or equal to about 0.4, and the water content is higher than or equal to about 9% by weight of the composition. The composition delivers thorough hair cleansing, good lather, good conditioning wet feel, clean rinse feel during use, leaving hair with very low residue on the hair surface. The use of the shampoo composition also provides high hair volume, smooth dry hair feel, and bouncy hair that is easy to style.

Methods for styling, in particular for straightening, keratin fibers, in particular human hair, in which (i) a styling agent comprising carbocisteine and/or a salt thereof is applied to the keratin fibers and left there, (ii) the fibers, after a leave-in time, are not rinsed, are optionally dried, (iii) the fibers are mechanically deformed from exposure to heat, significantly minimize the negative consequences of styling and reduce in particular electrostatic charging and hydrophilization of the hair.

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.

Disclosed herein are amino acid carbamate complexes, methods of synthesis thereof, oral care compositions comprising the same, and methods of making and using thereof.

The present disclosure concerns a hair treatment agent that contains, in a cosmetic supportwith respect to its weight a) from about 0.05 to about 5.0% by weight of zinc oxide, b) from about 0.05 to about 3.00% by weight of at least one anti-dandruff substance that is different from a), c) from about 0.10 to about 10.00% by weight of at least one saturated or unsaturated, straight-chained or branched C.sub.10-C.sub.24 carboxylic acid, and d) from about 0.01 to about 5.00% by weight of at least one amino acid.

A personal care composition comprising: at least a first phase and a second phase wherein said first phase comprises a) an aqueous structured surfactant phase comprising STnS where n is between about 0 and about 2.5; b); c) a structuring system comprising i. optionally, a non-ionic emulsifier; ii. optionally, from about 0.05% to about 5%, by weight of said personal care composition, of an associative polymer; iii. an electrolyte; and said second phase comprises a) a benefit phase comprising from 1% to about 50%, by weight of said personal care composition, of a hydrophobic benefit agent.
