Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition which is excellent in feeling of use and is used for face washing, body, hair, clothing, and tableware.

[0002]

2. Description of the Related Art Conventionally, detergent compositions have been mainly composed of higher fatty acid salts, facial cleansers containing dodecyl sulfate, polyoxyethylene-added dodecyl sulfate, acylglutamate, etc., whole body shampoo, hair shampoo. Etc. are known.

[0003]

However, when a higher fatty acid salt (soap) is blended, the hard water resistance is poor and the feeling of tightness after washing is large. Improvements in the feel and the like have been added. However, acylglutamates have the drawback of giving a slimy feel to the skin. The present invention has been made to solve the above problems, and an object of the present invention is to provide a detergent composition which is not irritating to the skin and has an excellent feeling after washing.

[0004]

The present invention provides the following general formula RCONHCH ₂ CH ₂ CH ₂ COOM (wherein R is a straight chain or branched chain saturated or unsaturated hydrocarbon group having 11 to 18 carbon atoms, M represents an alkali metal, an alkaline earth metal, an alkanolamine or an ammonium group.), And at least one of N-acylpiperidine acid salts represented by the formula is blended.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is described in detail below. The N-acyl piperidinate used in the present invention is, for example, a solution of a fatty acid chloride added dropwise while keeping an aqueous solution of biperidinate to react, and the reaction solution is used as a product as it is, or an acid is added to give a free acid. Separated and recrystallized again as a salt to produce. In addition, the hypereric acid is Japanese Patent Publication Sho 58-2.
In 6726, it is a substance proposed as a blending component of cosmetics that enhances the skin function, brings out the beautifying effect on the skin, and also has a hair growth effect.

In the above general formula representing N-acylpiperidine acid salt, R is a straight chain or branched chain saturated or unsaturated hydrocarbon group having 11 to 18 carbon atoms, and when the carbon number is less than 11, it is washed. When the strength is poor and conversely the number of carbon atoms exceeds 18, foaming is reduced. Therefore, examples of the fatty acid forming the acyl group include lauric acid, myristic acid, palmitic acid, isopalmitic acid, stearic acid, isostearic acid, and oleic acid. , Linolenic acid, coconut oil fatty acid, palm kernel oil fatty acid and the like. M represents an atom of an alkali metal such as sodium potassium, an atom of an alkaline earth metal such as calcium or magnesium, an alkanolamine such as triethanolamine, an ammonium group or the like.

Representative examples of N-acyl piperidinates include sodium lauric acid amide piperidineate,
Examples include coconut oil fatty acid amide piperidine acid triethanolamine and myristic acid amide ammonium piperidine acid.

The amount of the N-acyl piperidine salt of the present invention to be blended is preferably 3 to 40% by weight in the detergent composition from the viewpoint of the effect and stability of the obtained detergent composition.

In addition to the above N-acylpiperidine acid salt, the detergent composition of the present invention may contain components commonly used in detergent compositions. For example, fatty acid alkanolamide, polyoxyethylene alkyl ether,
Nonionic surfactants such as alkylamine oxide, betaine alkylaminoacetate, acylamidopropyl betaine, amphoteric surfactants such as 2-alkyl-N-carboxymethylimidazolium betaine, stearyl trimethylammonium chloride, lanolin fatty acid aminopropyl sulfate Cationic surfactants such as ethyldimethylammonium, cationic polymers, higher fatty acids, higher alcohols, dimethylpolysiloxane, lanolin derivatives, lecithin, oil components such as triglycerides, bactericides, pigments,
It is possible to mix commonly used ingredients such as fragrances into usual detergent compositions.

The present invention will be described in more detail with reference to the following examples. In addition, the compounding amount in each of the examples and the comparative examples is expressed as% by weight based on the total weight%. Moreover, the measurement of the effect is
It carried out based on the following evaluation methods.

(1) Evaluation method of feeling of use of face wash 20 panelists, 20 women aged 18 to 25 years old, conducted a sensory test by face washing, and said "washability", "feeling of foam", "easy to rinse", In response to questions such as "tightness after washing", "sliminess after washing", and "stimulation", "cleanability", "feeling of foam", "easy to rinse", "tightness after washing" The number of panelists who answered "No", "No slimy feeling after washing", and "No stimulus" are shown.

(2) Evaluation method of feeling of use of shampoo "Women feel", "Easy rinsing", and "Hair rinsing" when washing 20 women aged 18 to 25 with shampoo as panelists When asked about "squeaky feeling", "easiness of gathering" and "stimulation" of hair after towel drying, "feeling of bubbles", "easy to rinse", "no squeaky feeling", "easy to put together", "stimulation" The number of panelists who answered "No" is shown.

Examples 1 and 2 and Comparative Examples 1 to 4 (facial cleanser) The detergent compositions shown in Table 1 were prepared by a conventional method, and the feeling of use was evaluated, and the results shown in Table 2 were obtained. As the N-acyl piperidinate salt, sodium N-lauric acid amide piperidine acid was used in Examples 1 and 2, and N was used in Comparative Example 3.
-Sodium caproamide amide piperidine acid, comparative example 4
Sodium N-behenamide amide piperidine acid was used.
