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.

A detergent comprising (A) an anionic surfactant, (B) a quaternary ammonium cation-modified silicone, and (C) a cationic polymer is described. A mass ratio [(A)/(B)] of the component (A) to the component (B) is 30 or more and 5,000 or less, and a mass ratio [(B)/(C)] of the component (B) to the component (C) is 0.01 or more and 0.5 or less.

Personal care topical compositions at skin-tolerant pH with cystine which is solubilized or has small crystal size below 20 microns. A process of making the composition is also described.

Topical personal care compositions containing amino acids and 4-substituted resorcinols for potentiating glutathione synthesis within skin cells. The compositions can be used to improve skin appearance of chronological aging or photoaging, resulting from exposure to UV light/sunlight, or environmental pollutants. The compositions are also useful for attaining even skin color and reducing pigmentation, age spots and discoloration.

The present specification discloses a agent composition for modifying a pigment to dye that imparts tinting strength to the pigment, and a colorant composition in which a pigment is modified to dye using the same. According to the present disclosure, since the pigment has tinting strength on the skin, it is possible to realize various colors of the pigment as it is while having excellent durability when applied to the skin. Accordingly, the pigment may be comprised as a coloring agent in a cosmetic formulation requiring coloring by replacing the dye having a limitation in type and color when used in a cosmetic composition due to a stability problem for the skin. In addition, since the coloring agent according to the present disclosure has an irreversibly stabilized form, it can be widely used without being limited to the pH, formulation, etc. of the cosmetic composition.

A combination of N-acetyl-L-cysteine, selenium in the form of selenomethionine and melatonin, and a medical product or pharmaceutical composition comprising such combination, useful for the treatment of a variety of diseases and conditions is described. The combination of N-acetyl-L-cysteine, selenium in the form of selenomethionine and melatonin is also useful for cosmetic treatment of skin and as an antibacterial agent.

The present invention includes a method for the use of N-acetylcysteine (NAC), N-acetylcysteine amide (NAC A) or (2R,2R′)-3,3′-disulfanediylbis(2-acetamidopropanamide) (diNACA) for the prevention and treatment of radiation dermatitis, radiation damage to the skin, xeroderma pigmentosa or protect patients with xeroderma pigmentosa from skin damage caused by exposure to the sun or other radiation, bioweapons, chemical burns, heat burns, contact damage caused by friction, contact dermatitis, hypersensitivity reactions and skin wrinkles and dehydration, skin lightening, skin whitening, and/or skin improvement in a human that comprises administering to the human a therapeutically effective amount of NAC, NACA or diNACA.

A balanced formulation based on amino acids, which finds application in the field of functional and antiaging medicine, and in the cosmetic field for the well-being of hair, skin and nails is provided.

Products and methods are disclosed relating to a deodorant stick comprising mandelic acid.

The present disclosure provides compounds and 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.
