Description

The present invention relates to a transparent detergent composition excellent in conditioning effect after shampooing or skin protection effect after washing.

Conventionally, a transparent detergent composition has been studied as one of attempts to impart appearance distinction. For example, Japanese Patent Application Laid-Open No. 11-172296 (see Patent Document 1) discloses a technique in which a surfactant such as an anionic surfactant and a water-soluble acrylic / alkyl methacrylate copolymer are combined, and Japanese Patent Application Laid-Open No. 2003-55690. The Gazette (see Patent Document 2) combines an N-acyl amino acid salt, a cellulose-based natural polymer derivative, and a nonionic surfactant such as polyoxyethylene sorbitan fatty acid ester having an addition mole number of 10 to 30 of ethylene oxide. Technology has been reported. Although these transparent detergent compositions ensure a transparent preparation by adding a water-soluble component to the surfactant, the water-soluble component is washed away at the time of rinsing, and the conditioning effect after washing the hair and The skin protection effect after washing was not satisfactory. Further, for example, Japanese Patent Publication No. 2002-536311 (see Patent Document 3) reports a technique in which an anionic surfactant, an amphoteric surfactant, and a specific water-insoluble carboxylic acid ester are combined. In this technology, combinations with various water-insoluble carboxylic acid esters such as isopropyl palmitate and isopropyl myristate have been reported, but they are not always satisfactory in the conditioning effect after washing the skin and the skin protecting effect after washing. It was.

The object of the present invention has been made in view of such circumstances, and provides a transparent detergent composition excellent in conditioning properties after washing or the skin protecting effect after washing.

As a result of intensive studies to solve the above problems, the present inventors have found that one or more of anionic surfactant and / or amphoteric surfactant is 10 to 40% by weight, and glyceryl monooleate is added. It discovered that the objective transparent cleaning composition was obtained by mix | blending 0.2 to 5.0 weight% and polyoxypropylene glyceryl ether, and came to complete this invention.

The transparent detergent composition of the present invention is excellent in the conditioning effect after washing the hair or the skin protecting effect after washing while maintaining transparency.

These surfactants can be used alone or in combination of two or more. The blending amount can be 10 to 40% by weight, particularly 10 to 30% by weight, based on the total amount of the composition. When the blending amount is less than 10% by weight, sufficient foaming cannot be obtained, and when the blending amount exceeds 40% by weight, gelation or a sufficient conditioning effect or skin protection effect cannot be obtained.

Glyceryl monooleate used in the present invention is a monoester of oleic acid and glycerin, and the blending amount is 0.2 to 5.0% by weight with respect to the total amount of the composition. Among these, 0.2 to 3.0% by weight is preferable, and 0.3 to 2.0% by weight is more preferable. If the blending amount is less than 0.2% by weight, the conditioning effect after washing the hair or the skin protecting effect after washing is insufficient, and if it exceeds 5.0% by weight, the foaming property of the transparent detergent composition is increased. make worse.

The polyoxypropylene glyceryl ether used in the present invention is obtained by block copolymerization of polyoxypropylene with three hydroxyl groups of glycerin. In the present invention, the average number of moles of oxypropylene added in polyoxypropylene glyceryl ether is preferably 1 to 4 for each hydroxyl group of glycerin. Although the compounding quantity is not specifically limited, 0.1 to 2.0 weight% is preferable with respect to the composition whole quantity, and 0.3 to 1.5 weight% is especially preferable. If the blending amount is less than 0.1% by weight, the conditioning effect after shampooing or the skin protection effect after washing is insufficient, and if it exceeds 2.0% by weight, the foaming property of the transparent detergent composition will be reduced. make worse.

Examples of the cationic polymer compound used in the present invention include cationized cellulose, cationized guar gum, cationized fenugreek gum, cationized tara gum, and cationized locust bean gum.

These cationic polymer compounds can be used alone or in admixture of two or more, and the blending amount is not particularly limited, but is preferably 0.1 to 2.0% by weight based on the total amount of the composition. If the blending amount is less than 0.1% by weight, a synergistic conditioning effect cannot be imparted, and if it exceeds 2.0% by weight, foaming properties are impaired.

The detergent composition of the present invention can be produced by a conventional method, and is used for normal use as a detergent having a pH of 4.0 to 10.5. The cleaning composition of the present invention is mainly applied to skin and hair, and is used as a facial cleanser, cleansing agent, body shampoo, hair shampoo and the like.
