Description

Aerosol products

The present invention relates to an aerosol product.

In general, the aerosol product is composed of aerosol stock solution and propellant to perform a functional role of the product in a metal container of a certain size, and refers to a product that is sprayed in the form of spray particles or bubbles when sprayed by the aerosol valve operation. Herein, the aerosol stock solution and the propellant are referred to as the aerosol contents. Among the aerosol products, the representative products related to the hair are hair spray and hair mousse products. Hair spray products fix hair styles with excellent setting effects, and hair mousse products are the styling products that make a desired hairstyle.

However, when the hairspray product is used for the hair, it is sprayed with fine spray particles, so there is a disadvantage in that the hair sprayed product is set on the hair without knowing exactly the area sprayed on the hair. In addition, hair mousse products are applied to the hair after applying it to the hands once used, there is a problem that the hand comes to wipe the hands after using the product.

Accordingly, an object of the present invention is to solve the above-described problems, the valve orifice containing at least one setting component selected from cationic, anionic nonionic and amphoteric polymers and at the same time containing the foam component and the propellant Combination, solvent proportioning and propellant proportioning provide aerosol products which are sprayed into fine particles during spraying and foam is formed on the hair after spraying.

The present invention comprises an aerosol stock solution containing at least one setting component selected from cationic, anionic nonionic and amphoteric polymers used in hairspray and hair mousse, and a nonionic surfactant as a bubble component, and dissolving these components in a solvent. Fill the aerosol container with an aerosol propellant of 70:30 to 85: 15% by weight, wherein the button orifice diameter is 0.30 to 0.40 mm, the stem orifice diameter is 0.35 to 0.50 mm, and the housing orifice 0.35 ~ 0.45mm diameter, housing orifice diameter is greater than or equal to stem orifice diameter, sprayed with fine particles like spray when sprayed using aerosol valve without vapor step orifice, foam after spray (Foam) relates to the aerosol product is formed

Hereinafter, the present invention will be described in detail.

In general, the setting components used in the hairspray and the hair mousse are water-soluble polymer resins (polymers) and may be classified into cationic polymers, anionic polymers, nonionic polymers and amphoteric polymers.

The cationic polymer used in the present invention is a quaternary ammonium formed by the reaction of a copolymer of hydroethylcellulose and diaryldimethyl ammonium chloride, and a copolymer of dimethyl sulfate and vinylpinolidon and dimethylaminoethyl methacrylate. Polymers, polymers of vinylimidazonium chloride and vinylpinolidone, are suitable. Anionic polymers are copolymers of acrylic and methyl acrylics in tel, butyl ester copolymers of FMB / MP (monobutyl ester copolymers of polymethylvinylethermaleic acid), and nonionic polymers are polyvinylpi Nolidon, a copolymer of FV / V (polyvinylpyrrolidone / vinylacetate), a dimethicone (large methylpolysiloxane), and an amphoteric polymer is a methacryl oil ethyl betaine / methacrylate copolymer, etc. This is suitable.

In the present invention, the bubble component is a non-ionic surfactant, such as polyoxyethylene nonylphenyl ether or polyoxyethylene lauryl ether. As a solvent, water and ethanol were used, and as a propellant, a mixed gas of insoluble lpage and water-soluble dimethyl ether was used, and lp was controlled to foam after spraying on the hair, and dimethyl ether was foamed and sprayed. It acts to form spray particles. In addition, the number of types of aerosol valves by the orifice diameter combination of more than 10,000 species, but in the injection according to the present invention is injected into fine particles to form a formulation in which the foam is formed on the hair after the injection is very narrow combination of orifice diameter It is limited to one range.
