The invention relates to spray-dried, washfast dye compositions (preferably in the form of pigment powders) having a bleeding rate of ≤0.5% and consisting of water-soluble functional dyes, preferably food dyes, which are firmly incorporated in a silica matrix. Apart from low bleeding of dye, these compositions are remarkable for their high stability to pH changes and/or ascorbic acid. The invention is also directed to the production of the dye compositions and the use thereof. The dye compositions are preferably employed in coloring foods, cosmetics, pharmaceutical products, but also in other uses.

It is an object of the present disclosure to provide an agent for coloring keratinous material, in particular human hair, comprising (a1) at least one amino-functionalized silicone polymer, and (a2) at least pigment,
the weight ratio of all the pigments (a2) contained in the composition to all the amino-functionalized silicone polymers (a1) contained in the composition, i.e., the weight ratio (a2)/(a1), being not more than 0.95.

A second subject matter is a method for dyeing keratin material, wherein the agent is applied to the keratin material.

The subject of the present disclosure is a method for dyeing keratinous material, in particular human hair, comprising the following steps: Application of an agent (a) to the keratinous material, wherein the agent (a) comprises: (a1) at least one organic silicon compound selected from the group of silanes having one, two or three silicon atoms, and
(a2) at least one hydroxycarboxylic acid ester,
(a3) at least one diol and Application of an agent (b) to the keratinous material, wherein the agent (b) comprises: (b1) at least one sealing reagent,
wherein at least one of the agents (a) and (b) further comprises at least one colorant compound selected from the group of pigments and/or direct dyes.

A method for coloring keratinous material, in particular human hair, includes the step of applying on the keratinous material: a first composition (A) comprising: (A1) one or more organic C.sub.1-C.sub.6 alkoxysilanes and/or condensation products thereof, and (A2) at least one colorant compound selected from the group comprising pigments and direct dyes, and a second composition (B) comprising (B1) a copolymer of styrene and maleic acid (anhydride).

The present invention relates to an anhydrous composition for dyeing human keratin fibers, comprising at least one natural dye, at least one hydrazono and/or azo cationic synthetic direct dye and at least one compound of formula (I) in which Y represents a C.sub.1-C.sub.4 hydroxyalkyl group or a C.sub.1-C.sub.4 hydroxyalkyloxy radical, n denotes an integer ranging from 0 to 5, and X, which may be identical or different, represents a C.sub.1-C.sub.4 alkyl radical or a halogen. The invention also relates to a process for dyeing human keratin fibers using this composition.

The present invention relates to a composition for preventing or treating scars and a preparation method therefor. The composition, according to one aspect, comprises a pigment and silicone oil, and may be stably formulated into a formulation adequate for spreading on the skin, and may inhibit the formation of scars or reduce already existing scars by forming a membrane on the skin, and has an effect whereby scars may be concealed by the pigment stably dispersed in the composition.

A process for dyeing keratinous material is disclosed. The process includes applying an agent (a) and an agent (b) to the keratinous material. The agent (a) comprises (a1) at least one organic silicon compound, and (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound. A multi-component packaging unit is also disclosed, and comprises, separately packaged, a first container comprising an agent (a′), a second container comprising an agent (a″), and a third container comprising an agent (b). The agent (a′) comprises (a1) at least one organic silicon compound. The agent (a″) comprises (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound.

An agent for dyeing keratinous material, in particular human hair, is disclosed. The agent is a colorant composition comprising at least one amino-functionalized silicone polymer, at least one color-imparting compound, and at least one organic carbonic acid ester. A process (method) for dyeing keratinous material with the agent is also disclosed. The process includes applying a colorant comprising the agent to the keratinous material, exposing the keratinous material to the agent for an exposure time sufficient for the color-imparting compound to act on the keratinous material, and rinsing out the keratinous material with water.

Described herein is a nanofibre matrix comprising 100% natural biopolymers selected from polysaccharides and/or proteins with optional functional ingredients for use as cosmetic products. More specifically, nanofibre matrix manufactured by electrospinning methods comprising a dry sheet without containing any preservatives, surfactants, solvents and crosslinkers. To use nanofibre cosmetic products, simply wet skin and then apply the nanofibre to skin. Functional ingredients may be optionally incorporated within the nanofibre matrix during electrospinning to provide different cosmetic effects. Functional ingredients offer skin benefits such as moisturizing, anti-ageing, wrinkle reduction, brightening, antioxidant and acne treatment. Functional ingredients can be essential oil where it is incorporated into nanofibre matrix to provide scent effect to cosmetic products. Functional ingredients can also be natural dye where it is incorporated in nanofibre matrix to make coloured nanofibres. Coloured nanofibres can be used for makeup products such as blush, eye shadow, eyebrow, nail polish, lipstick, contouring and hair dye product. The nanofibre matrix comprising 100% natural biopolymers with or without functional ingredients can be processed to assorted shapes or easily cut by consumers for using on different areas of skin for different purposes.
