For coloring foods, nutritional supplements, cosmetic or pharmaceutical products, the invention provides a dye, which contains at least one pigment in the form of a water-insoluble sulfate, carbonate, or phosphate of at least one alkaline earth metal, which is selected from the group consisting of calcium sulfate, magnesium phosphate, calcium phosphate, and magnesium carbonate.

The disclosure discloses a liquid foundation using starch as a filler and a preparation method thereof, belonging to the technical fields of deep processing of starch and preparation of cosmetics. In the disclosure, starch is modified by an OSA reagent and then homogenized and micronized to obtain a starch filler; powder materials and the water phase in the formula of the liquid foundation are sequentially added to the oil phase at a certain temperature; the mixture is sheared at low speed, homogenized, and cooled to room temperature; and the starch filler is added to prepare the liquid foundation using starch as a filler, wherein the formula includes 10-20 parts of oil phase, 65-75 parts of water phase, 5-10 parts of toner, and 5-15 parts of starch filler. The starch filler in the disclosure is hypoallergenic, environmental and safe, and the liquid foundation containing the starch filler is refreshing and not easy to clog pores, solves the problems of traditional fillers which are thick and greasy, unbreathable, easy to aggravate facial acne, and the like, and is in line with the current propensity to consume of consumers for green and safe beauty products.

An ink composition for temporary tattoos which can be removed when desired and the process for producing it. The ink is formulated on the basis of biologically tolerable, natural pigments/dyes and is encapsulated in a carrier made of a material which, upon being disturbed by an external energy, can release the dye in the tissue in order to be absorbed by the body, thereby eliminating the tattoo without a trace.

The invention relates to a hair treatment method for treating hair by using a hair treatment tool (1). The hair treatment tool (1) includes: a fiber structure member (5) that retains a hair cosmetic; and a liquid-impermeable sheet (3) to which the fiber structure member (5) is fixed. The fiber structure member (5) retains a hair cosmetic that includes a pigment and a film-forming resin, and is sealed in a packaging (2). The hair treatment method of the invention treats hair by: exposing a surface of the fiber structure member (5) of the hair treatment tool (1); and bringing the fiber structure member (5) into contact with hair, and in this state, moving the fiber structure member (5) in a direction of orientation of the hair.

The subject of the present disclosure is a process for dyeing keratinous material, in particular human hair. In one example, the process includes applying an agent (a) to the keratinous material. The agent (a) contains at least one organic silicon compound from the group of silanes with one, two or three silicon atoms. The agent (a) further contains at least one silicone polymer. An agent (b) is applied to the keratinous material. The agent (b) contains at least one pigment.

Water-in-oil type emulsion cosmetics containing (a) polyaspartic acid or a salt thereof, (b) a spherical powder, (c) an oily component, (d) a lipophilic surfactant, (e) a pigment, and (f) water can achieve superior makeup effects, good moist feeling, superior emulsion stability and pigment dispersibility.

Cosmetic compositions capable of forming a multilayer structure after application to a keratinous material are provided, as well as methods of applying such compositions to a keratinous material.

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 one pigment, and (a3) at least one phosphorus-comprising organic compound.

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

A process for decolorizing keratinous material which has been colored by the application of at least one pigment is disclosed. The process comprises applying to a dyed keratin material a decolorizing agent comprising at least one amphoteric and/or zwitterionic surfactant and a pH of from about 1.0 to about 4.3. The process further comprises rinsing the decolorizing agent from the keratin material after a contact time. A method for dyeing and later decolorizing human hair is also disclosed, and comprises applying a colorant to the hair to give a dyed hair, the colorant comprising at least one amino-functionalized silicone polymer and at least one pigment; applying to the dyed hair the decolorizing agent to give a decolorized hair; and rinsing the decolorizing agent from the decolorized hair. A multi-component packaging unit comprising a first container comprising the colorant and a second container comprising the decolorizing agent is also disclosed.

A method for producing a powder solid composition including a base containing non-volatile liquid oil, the method includes: blending wax in a powder form into the base; dispersing the base in a solvent; volatilizing the solvent at a first temperature where the wax does not dissolve; and heating the base at a second temperature where the wax dissolves, wherein a blending amount of the non-volatile liquid oil is 15% by mass or more and 40% by mass or less with respect to the base.
