ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
(1) The present invention relates to a detergent composition which contains an alkali metal N-methyltaurate salt or an organic alkali N-methyltaurate salt of a fatty acid.
(2) The present invention relates to a detergent composition which contains an alkali metal taurate salt or an organic alkali taurate salt of a fatty acid.
(3) The present invention relates to a detergent composition which contains an alkali metal hypotaurate salt or an organic alkali hypotaurate salt of a fatty acid.
(4) The present invention relates to a detergent composition which contains one or more types chosen from among an alkali metal taurate, N-methyltaurate or hypotaurate salt and an organic alkali taurate, N-methyltaurate or hypotaurate salt of a specific organic acid.
(5) The present invention relates to a detergent composition which contains one or more types chosen from among an alkali metal taurate, N-methyltaurate or hypotaurate salt and an organic alkali taurate, N-methyltaurate or hypotaurate salt of a acylated peptide.
2. The Prior Art
For the purpose of improving foaming and foam quality, soaps have been frequently used as detergents in products such as cleansing foam, body shampoo and shampoo. Of these, the most frequently used are soaps made from salts of alkali metals, such as sodium and potassium, with fatty acids. On the one hand, they have the advantages of a lower cost, good foaming and a creamy foam quality. On the other hand, they have shortcomings including poor foaming at a neutral pH, creaking feeling and a stretched feeling after use.
In order to address the foaming at a neutral pH and the creaking feeling, soaps made with a fatty acid and a weak base such as triethanol amine and lysine have been used. However, they have problems in that they have the amine odor due to the weak base part, the foam quality deteriorates and a refreshing feeling is harder to achieve, and they cannot be blended into solid products due to a lower dissolution point (Krafft point).
BRIEF SUMMARY OF THE INVENTION
The object of the present invention is to provide a detergent composition which has better foaming and foam quality, less pH dependence of the foaming, creamy foaming, no creaking feeling or stretched feeling and no offensive odor.
The inventors conducted earnest research based on the above mentioned problems and discovered that a detergent composition containing an alkali metal N-methyltaurate salt or an organic alkali N-methyltaurate salt of a fatty acid is superior to conventional products because it has better foaming and foam quality, less pH dependence of the foaming, creamy foam, no creaking feeling or stretched feeling and no offensive odor, thus completing the present invention.
