Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition for washing the body, especially for hand washing. It is an old soap for hand washing, which is excellent in initial foaming detergency and excellent in touch and finish to hand skin. That is, solids of fatty acid sodium and liquids of fatty acid potassium and alkanolamine are well known and used for many years. The goodness of the fatty acid system is that it has excellent initial foaming, has a smooth feel, has good detergency on a moderate alkali side, and has excellent foam finish and finish.

[0002]

2. Description of the Related Art Conventionally, as a washing product for body washing, a neutral or weakly acidic surfactant is used in order to save the pH of soap. (3) Alkyl sulfate (4) Alkyl ether sulfate (5) α-olefin sulfonate (6) Alkylsulfonate (7) Alkyl ether carboxylate, etc. Since there is nothing to surpass the fatty acid salt in terms of foam removal, stability and feel, it is necessary to increase the amount of other surfactants, which limits the original function. In addition, since it contains phosphorus, sulfur, and nitrogen as essential components, eutrophication of water quality, secondary pollution,
There is a concern that it may be an obstacle to water purification, such as the generation of offensive odor. For this reason, the alkali-derived fat acts on the surfactant of the fatty acid salt to act as a bulk on the skin and primary irritation (occurrence of erythema). Castor oil, jojoba oil, squalane, turtle oil, lower grade Oils such as fatty acid esters (eg, IPM.IPP, etc.), paraffin, petrolatum, silicone derivatives, safflower oil, hardened tallow, hardened rice bran oil, α-oryzanol, β-carotene, vitamin A, vitamin E, egg yolk lecithin, soy lecithin To join. Alternatively, various kinds of aqueous collagen, elastin, albumin, DNA, carboxycellulose, hydroxycellulose, sodium alginate, xanthan gum, gum arabic, cationized cellulose, honey, lactone derivative, and other herbal extracts such as plant extracts (aloe, chamomile, rosemary, Cucumber extract, menthol, etc.) and polyols (polyglycerin, sorbitol, xylitol, glucose,
(PEG, PPG), etc., it is difficult to obtain effective results. This is because the fatty acid salt forms a metallic soap under hard water (in mineral ions), causing a rough and squeaky feeling on the hand skin and does not fuse well.

[0003]

[Problems to be Solved by the Invention] The present invention is attracting attention in skin cosmetics, joints and eye treatments so as to make use of the most ideal surfactant-based characteristics of fatty acid salts and to have a synergistic effect with these characteristics. The combination of hyaluronic acid and polyhydric alcohol, which is a high-molecular-weight polymer, makes good use of the detergency of fatty acid salts, and also focuses on the fact that hyaluronate has good hard water resistance and can maintain the characteristics of fatty acid salts, and is aromatic. The addition of terpene-based citrus peel oil as a sex and superfatting agent resulted in an ideal body cleansing composition. Sodium fatty acid as the anionic surfactant of a fatty acid-based main component used in the present invention having an alkyl group of C ₁₂ -C _18, potassium, ammonium, monoethanolamine, triethanolamine, monoisopropanolamine, etc. length Chain alkyl fatty acid salt, polyoxyethylene (EO, 3-5 mol)

a ⁺ . K ⁺ . NH ₄ ⁺ . ), C ₁₂ -C ₁₆ alkyl sarcosine salts (Na ⁺ .K ⁺ .NH ₄ ⁺ .triethanolamine) and the like. The characteristics of these fatty acid surfactants are excellent in foaming and foam removal. In other words, having the goodness of the original soap. It has good biodegradability. It has a good hand skin feel, and contains very small amounts of P and N, which lead to water pollution such as eutrophication. It is an ideal surfactant for body washing. . On the other hand, in order to compensate for the weak points of fatty acid surfactants, fatty acid nonionic surfactants such as coconut oil fatty acid diethanolamide, laurylamine oxide, polyoxyethylene (EO: 2 to 10 mol) coconut oil fatty acid monoethanolamide, Lauryl fatty acid diisopropanolamide, and betaine-based zwitterionic surfactants such as coconut oil fatty acid amide propyl dimethylaminoacetic acid betaine, coconut oil isidazolinium betaine, etc. The generation of soap scum (metal soap) can be prevented, and the sliminess peculiar to soap can be alleviated. Of course, polyoxyethylene alkyl ether, polyoxyethylene hydrogenated oil, sorbitan fatty acid ester, glycerin fatty acid ester,
You can use them together. Even if the PH range of the original fatty acid-based anionic surfactant is reduced to 8 units, the foaming and feel do not change, but the emulsifying and dispersing power can be stabilized. Thus, the combination of other concomitant substances can be maintained in a good state. In particular, it is advantageous to stabilize the quality of citrus peel components, mainly D-limonene. Hyaluronic acid is a polysaccharide-based hydrophilic polymer with a molecular weight of 50,000 to 3,000,000 contained in birds' stag, cartilage, vitreous of bovine eyes, and calendar, and has excellent water retention ability and structure maintenance. Drugs and
Often used in skin care cosmetics. In addition, mass production by biotechnological fermentation has become possible, and its importance is increasing. There is also a powder type, but usually there is a hyaluronate (mostly Na) powder, but in order to make it easy to use, it is in the form of a viscous transparent liquid of an aqueous solution of 0.5 to 2% (viscosity 500 cp or more and 20 cc). Use of things is better workability. The amount is solid content
0.005 to 0.10 W% is sufficient. If it exceeds 1 W%, it may cause coagulation of polymer or ionic surfactant.
It has poor stability with high affinity substances and is easily separated. This phenomenon applies to all hydrophilic polymers. or,
If it is less than 0.005 W%, the effect of the hyaluronate is rare and hard to confirm. Particularly, the fatty acid salt and the hyaluronic acid are in the same amount, and the following stability is preferred over other anions. a. Triethanolamine lauryl sulfate (10%) b. Coconut oil sodium glutamate (10%) c. Sodium lauryl phosphate (10%) d. Polyoxyethylene (EO: 3) lauryl ether sodium sulfate (10%) e. Alkyl (C15-C16) sodium sulfonate
