Description

Foam spray hair cosmetic composition

The present invention relates to a foam injection-type hair cosmetic composition containing high molecular weight silicone and silicone oil, and more particularly, to a mixture of high molecular weight silicone, silicone oil and polydimethylsiloxanyl bee's wax of HLB 5-15. Emulsification with nonionic surfactants improves the stability of the emulsion, together with quaternary ammonium polymers, and maintains the emulsion emulsion at a pH of 4-7 for a longer and more stable silicone emulsion. The present invention relates to a foaming-type hair cosmetic material which has an improved effect and is excellent in preventing hair damage.

In general, hair is easily damaged by cracking or drying by frequent washing and combing, heating by a dryer, dyeing, bleaching process and permanent wave treatment, and the damaged hair is almost impossible to recover to its original state.

Accordingly, hair cosmetic products for the purpose of alleviating damage to hair and protecting hair have been introduced. Among them, hair cosmetics using high molecular weight silicone derivatives or silicone oils are representative. However, most of these products are types of products that are applied directly to the hair by taking the contents directly into the hands, and there are problems in using them such as the need to wash the contents on the hands after use and to massage several times or several times for uniform application. . In order to solve such a problem, hair cosmetics in which the form of the product is foam-injected are introduced, and examples thereof include Korean Patent Nos. 90-4087, US Patent Nos. 4,839,167, and Japanese Patent No. 4-134017. The composition described in Korean Patent No. 90-4087 is a silicone emulsion containing high molecular weight silicone and a low boiling oil, and the stability of the contents gradually decreases during long-term storage, making it difficult to uniformly apply the silicone derivative to the hair. When used in aerosol form, due to poor usability is somewhat limited in its utilization. The silicone emulsion described in U.S. Patent No. 4,839,167 is characterized in that the dimethylpolysiloxane polyoxyalkylene copolymer having a melting point of 20 to 45 ° C is emulsified with a nonionic surfactant having an HLB of 10 or less. The silicone emulsion of -134017 is characterized in that the polysiloxane is emulsified using polyoxyethylene alkylphenyl ether phosphoric acid. However, the compositions disclosed by these two patents also reduce the stability of the contents upon long-term storage, and do not provide uniform applicability when applied to hair, thereby limiting their utilization.

Accordingly, the present inventors have intensively studied to solve the above problems, and as a result, emulsified a mixture of high molecular weight silicone, silicone oil and polydimethylsiloxanyl bee's wax with a nonionic surfactant of HLB 5-15 By increasing the stability of the silicone emulsion, containing the quaternary ammonium synthesis, and maintaining the pH of the silicone emulsion at 4-7, the silicone emulsion can be maintained more stably for a long time, and the contents can be used as a foam spray type, spreadability and The present inventors have found that a silicone emulsion composition with improved hair coating strength can be obtained and completed the present invention.
