Description

Detailed Description of the Invention [Industrial Application Field] The present invention is directed to a detergent used for hair or body shampoo, clothing or dishwashing detergent, etc. containing an anionic phosphate ester surfactant and an alkyl glycoside. The present invention relates to a drug composition.

[Prior Art] Generally, anionic surfactants such as alkyl sulfonates are used as main ingredients in detergent compositions for hair, clothing, and tableware, but there are concerns that they may irritate the skin and roughen hands. There is. In response to this, attempts have been made to use anionic phosphate ester surfactants as anionic surfactants, but when anionic phosphate ester surfactants are blended, the irritation is slightly alleviated. Because it is a surfactant with a physical charge, it is not as perfect as nonionic surfactants that do not have a charge. Generally speaking, anionic phosphate ester surfactants provide a smooth texture when used on hair, but have the drawback of lacking foaming power and, in particular, lacking a rich feeling in foam quality.

[Problems to be Solved by the Invention] In view of the above circumstances, the inventors of the present invention have conducted extensive research, and as a result, have combined an anionic phosphate ester surfactant and an alkyl glycoside in a specific ratio and amount. In this case, the present inventors have discovered a cleaning composition that is less irritating to the skin, has foaming power, and has excellent rich foam quality, and has completed the present invention.

[Means for Solving the Problems] That is, the present invention has the following general formula (A) [wherein X is a linear or branched saturated or unsaturated hydrocarbon group having 10 to 18 carbon atoms or a fatty acid] The monoamide group, R
are the same or different, hydrogen or methyl group, m is O~6
and Y represents hydrogen, an alkali metal group, or Y] and the following general formula (B) [wherein aba1 to An integer of 15, n represents an integer of 7 to 19. This is a cleaning composition characterized by containing one or more non-sulfuric surfactants represented by the following.

The configuration of the present invention will be explained in detail below.

The anionic phosphate ester activator used in the present invention is represented by the above general formula (A), and specific examples include oleyl phosphoric acid and its triethanolamine salt, polyoxyethylene (3 mol addition) isostearyl phosphoric acid and its sodium salt, coconut fatty acid monoethanolamide ethyl polyoxyethylenyl (2 mole addition) phosphoric acid and its sodium salt, polyoxyethylene (3 mole addition) lauryl phosphoric acid and its sodium salt, poly Oxypropylene (2 mol addition) Lauryl phosphoric acid and its triethanolamine salt, polyoxyethylene (2 mol addition) Polyoxypropylene (2 mol addition) Lauryl phosphoric acid and its sodium salt, di[polyoxyethylene (3 mol addition) ) laurylcholic acid and its triethanolamine salt, etc.

The alkyl glycoside which is the nonionic surfactant used in the present invention is represented by the above general formula (B),
Those having a straight chain alkyl group having 8 to 20 carbon atoms, especially those having a straight chain alkyl group having 10 to 16 carbon atoms are excellent in foaming and rich feeling, and these may be used alone. . The sugar moiety is glucose or an oligosaccharide based on glucose. The number of glucose units is 1 to 15, preferably 1 to 5, and the bonds between glucose may be α, β, or a mixture thereof.

The amount of the anionic phosphate ester active agent and alkyl glycoside of the present invention is 2 to 50% by weight, preferably 5 to 30% by weight, based on the total amount of the cleaning composition. 2
If the amount is less than 50% by weight, sufficient foaming power cannot be obtained due to the lack of surfactant, and if the amount exceeds 50% by weight, the skin will be irritated, which is not preferable.

Further, the weight ratio of anionic phosphate ester activator/alkyl glycoside is in the range of 0.01 to 100, preferably in the range of 0.1 to 10. In this composition, if the weight ratio is less than 0.01, it lacks a rich feeling, and if it exceeds 100, it will cause strong irritation to the skin, which is not preferable.

In the present invention, in addition to the above-mentioned essential ingredients, it is desirable to incorporate an amphoteric surfactant into the cleaning composition, as this increases the roughness and richness of the foam quality, depending on the application. Specifically, 2-undecyl-N, N, N
-(Hydroxyethylcarboxymethyl)-2-imidacillin sodium, 2-cocoyl-2-imidazolinium hydroxide-1-carboxyethyloxy-2-
imidacillin amphoteric surfactants such as sodium, 2-
Examples include betaine-based amphoteric surfactants such as heptadecyl-N-hydroxymethyl-N-hydroxyethylimidazolium betaine and lauryldimethylaminoacetic acid betaine, as well as alkylbetaines, aminobetaines, and sulfobetaines. These amphoteric surfactants may be used alone or in combination of two or more. The blending amount is preferably 0.1 to 20% by weight, more preferably 5 to 15% by weight, based on the total amount of the composition.

Furthermore, the detergent composition of the present invention may contain components and additives that are commonly used in detergents. That is, oils such as higher alcohols, silicone oils, liquid paraffin, and ester oils, water-soluble polymers such as methylcellulose and hydroxymethylcellulose, cation-modified cellulose ether derivatives (Polymer JR (manufactured by Union Carbide Corporation)), polyglycol/polyamine condensation (Polycoat H (manufactured by Henkel Hakusuisha)), polydimethyldiallylammonium halide (Marcoat 10)
0 (manufactured by Merck & Co.), a copolymer of dimethyldiallylammonium halide and acrylamide (Marquat 55)
0 (manufactured by Merck & Co.)), nonionic surfactants such as polyoxyethylene hydrogenated castor oil and polyoxyethylene alkyl ether, natural extracts of plants and animals and their derivatives, and organic acids such as citric acid and lactic acid. , inorganic salts such as sodium chloride, fragrances, coloring agents, preservatives, chelating agents, ultraviolet absorbers, etc. may be added as appropriate within a range that does not impair the effects of the present invention.

[Effects of the Invention] The present invention provides a cleansing composition that is less irritating to the skin, has excellent foaming power, and has excellent rich foam quality.
