A process is provided for dyeing keratinous material. The process includes (1) providing an agent (a) that includes (a1) at least one amino-functionalized silicone polymer and (a2) at least one colorant compound. The process further includes (2) providing an agent (b) that includes (b1) water and (b2) at least one fat component. The method includes (3) preparing an application mixture by mixing agents (a) and (b) and (4) applying the application mixture to the keratinous material. Further, the method includes (5) exposing the application mixture to the keratinous material and (6) rinsing the application mixture with water.

A process and a kit-of-parts are provided for dyeing keratinous material, in particular human hair. The process includes applying a coloring agent (a) to the keratinous material, the agent (a) comprising (a1) at least one amino-functionalized silicone polymer, (a2) at least one color-imparting compound, and (a3) at least one nonionic surfactant. The process further includes applying a post-treatment agent (b) to the keratinous material, the agent (b) comprising (b1) at least one acid.

Systems and methods for application of cosmetic designs are described. In an embodiment, the system includes a visible light mirror, comprising a first portion being at least partially transparent to visible light; a camera, optically coupled with the visible light mirror to receive visible light via the first portion; an illumination source, physically coupled with the visible light mirror and configured to emit a plurality of discrete wavelength channels; and a computer system, electronically coupled with the camera and the illumination source, and comprising one or more processors and a non-transitory computer readable storage medium storing instructions that, when executed by the one or more processors, cause the one or more processors to perform one or more methods of the present disclosure.

The present invention relates to a cosmetic product using photochromic powder and a method of manufacturing the same. More particularly, the present invention relates to a cosmetic product using photochromic powder and a method of manufacturing the same, in which various formulations of cosmetic products used for the skin, lips, nails, and hair are manufactured using a photochromic powder pigment manufactured using ingredients that are harmless to the human body so that the color thereof is changed when the cosmetic products are exposed to ultraviolet light, thereby making it possible to satisfy user demand both for fun and for aesthetic improvement and to help a user create a unique style.

A process and a kit-of-parts are provided for dyeing keratinous material, in particular human hair. The process includes applying a coloring agent (a) to the keratinous material, the agent (a) comprising (a1) at least one amino-functionalized silicone polymer, (a2) at least one color-imparting compound, and (a3) at least one nonionic surfactant. The process further includes applying a post-treatment agent (b) to the keratinous material, the agent (b) comprising (b1) at least one acid.

A temporary liquid crystal hair colour composition for temporarily colouring hair, particularly, non-lightened, unbleached or dark hair is provided. The colour composition contains an encapsulated liquid crystal and a coating composition comprising a thickening agent and a rheology modifier and the hair retains a natural feel while exhibiting a vibrant colour effect.

An antimicrobial composition suitable for use on human skin and containing a UV-detectable compound that will allow for detection of the application of the composition, using a UV-light source. A kit comprising such an antimicrobial composition and a UV-light source.

Described herein is UV-responsive ink capable of informing the user of UV exposure in real time, and a sun care kit incorporating the same.

This invention is directed to an effect pigment dispersion comprising a PVD-aluminum pigment, a leafing additive and an oil suitable for cosmetic skin care or color cosmetic applications, wherein a) the amount of the PVD-aluminum pigment is in a range of 8 to 30 wt.-%, b) the amount of the oil is in a range of 70 to 90 wt.-%, each based on the total weight of the effect pigment dispersion and c) the leafing additive is partly adsorbed on the surface of the PVD-aluminum pigment and partly an excess additive dissolved in the oil, wherein the amount of excess leafing additive is in a range of 0 to 25 wt.-%, based on the weight of PVD aluminum pigment. Further cosmetic skin care of color cosmetic formulations containing this effect pigment dispersion are described.

A method is described for the treatment and/or prevention of damaged keratin in a keratin-containing tissue, comprising the steps of: applying on the keratin-containing tissue a cosmetic composition comprising molecules carrying at least one light reactive functional group, and at least one photoinitiator; and leaving to process with exposure of the keratin-containing tissue to light, the light being of a wavelength suitable for activating said at least one photoinitiator. A cosmetic composition is also described comprising molecules carrying at least one light reactive functional group and at least one photoinitiator; and its use.
