DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a dough odor improving agent for a composition containing a surfactant and a fragrance improving agent for a composition containing a surfactant and a fragrance.

[0002]

2. Description of the Related Art Hair cosmetics such as shampoos and rinses and whole body washings such as body soaps are used by human beings among other washings, and smells when used, such as scalp, hair and whole body skin. There are many scenes to worry about, and a particularly pleasant fragrance is required during and after use. Therefore, fragrances used in shampoos, rinses, body soaps, facial cleansers, etc. are given special attention, and do not have an unpleasant odor even for the fabric odor before perfuming the fragrances, and hinder the odor of the fragrances used. Instead, it has been desired to improve it.

[0003] However, surfactants used in cosmetics such as these detergents greatly affect the odor of the dough before perfuming the fragrance, and particularly unreacted products and by-products contained in the surfactant. Odors such as higher alcohols, polyhydric alcohols, aldehydes, amines, and fatty acids have caused the odor of the dough to be greatly reduced. Therefore, for the purpose of masking, matching, and the like of the dough odor, more fragrance is used, and more fragrance is required to be used. However, this has caused a decrease in the performance of the originally used fragrance, that is, a deterioration in the comfort of the fragrance at the time of use and after use.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide an agent for improving the dough smell of a composition containing a surfactant and an agent for improving the flavor of a composition containing a surfactant and a fragrance. Is to do.

[0005]

Means for Solving the Problems The present inventors examined the dough odor of various surfactant-containing compositions and the change of the odor when a perfume was added thereto. α- (alkylcyclohexyloxy) -β-

The dough odor improving agent of the present invention may contain, in addition to the compound (1), a solvent compatible with or capable of dissolving the compound (1). These solvents are not particularly restricted but include, for example, lower alcohols such as ethanol, propanol and butanol, and propylene glycol, dipropylene glycol and the like. Among these solvents, in terms of compatibility or dissolution, ethanol, propanol, lower alcohols such as butanol are preferable, but as a dough odor improver, from the viewpoint that the odor of the solvent itself is preferably closer to odorless, Dipropylene glycol is particularly preferred. Further, the blending amount is preferably 10% or less, particularly preferably 5% or less, in the dough odor improving agent.

The dough of the dough odor improving agent of the present invention is not particularly limited as long as it is a composition containing a surfactant, but the surfactant and unreacted products and by-products during the production of the surfactant are used. (Eg, higher alcohols, polyhydric alcohols, aldehydes, amines, fatty acids, etc.). This composition includes not only a composition containing only a surfactant but also a dough (not including a fragrance) before the cosmetic is manufactured. The compounding amount of the compound (1) in the composition containing these surfactants is preferably 30% by weight (hereinafter, simply referred to as%), particularly 30 to 90%, more preferably 40 to 70% of the total composition. .

(11) N-alkyl (or alkenyl) glycolate
Amidosulfate, (12) alkylbenzene sulfonate and the like.

The amount of the anionic surfactant to be added to the fabric, that is, the composition, is preferably 0.1 to 30% from the viewpoint of foaming and fragrance.

As the nonionic surfactant, for example,
(13) polyoxyalkylene (ethylene, propylene, etc.) alkyl (or alkenyl) ether, (14)
Polyoxyalkylphenyl ether, (15) higher fatty acid alkanolamide or an alkylene oxide adduct thereof, (16) sucrose fatty acid ester, (17) glycerin fatty acid monoester, and the like.

The amount of the nonionic surfactant to be added to the fabric, that is, the composition is preferably 0.1 to 30% from the viewpoint of foaming and fragrance.

As the cationic surfactant, a quaternary ammonium salt, particularly a mono- or di-long-chain quaternary ammonium, is preferred. Here, as the mono long chain or di long chain, an alkyl group, an alkenyl group, a hydroxyalkyl group, an alkylcarbonylaminoalkyl group, an alkenylcarbonylaminoalkyl group, an alkylaminocarbonylalkyl group, an alkenylaminocarbonylalkyl group, an alkoxyalkyl group, Examples include an alkenyloxyalkyl group, an aliphatic acyloxyalkyl group, an alkoxycarbonylalkyl group, an alkenyloxycarbonylalkyl group, and the like. Here, the alkyl portion or the alkenyl portion may be long or branched. More specifically, JP-A Nos. 62-141176, 63-50574, 63-260991, 63-2609992, and 6

Preferred examples include mono-long (straight or branched) alkyl trimethyl ammonium salts, di-long (straight or branched) alkyl dimethyl ammonium salts, and mono-long (straight or branched) alkyl dimethyl benzyl ammonium salts And dilong-chain (linear or branched) alkylmethylbenzylammonium salts, and dilong-chain (linear or branched) alkylmethylhydroxyethylammonium salts.

The amount of the cationic surfactant to be added to the fabric, that is, the composition, is preferably 0.1 to 15%, for example, from the viewpoint of smoothness to hair and scenting.

Examples of the amphoteric surfactant include, for example, imidazoline type, amide amino acid salt, carbobetaine type, alkylbetaine type, alkylamidobetaine type, alkylsulfobetaine type and the like.

The unreacted products and by-products contained in this composition and its surfactants cannot be all limited, but include, for example, lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, oleyl alcohol Polyhydric alcohols such as glycerin, pentaerythritol, sorbit, and sorbitan; aldehydes such as lauryl aldehyde, myristyl aldehyde, cetyl aldehyde, stearyl aldehyde, and oleyl aldehyde; lauryl amine, dilauryl amine, lauryl dimethyl amine; Amines such as stearylamine, distearylamine, stearyldimethylamine; acetic acid, propionic acid, butyric acid,

Since the surfactant-containing composition has an improved dough odor, the composition in which the fragrance is added to the composition can exhibit the odor of the used fragrance well and improve the fragrance. Such fragrances are particularly limited as long as they are fragrances usually used as fragrances for products such as hair cosmetics such as shampoos and rinses, systemic detergents such as body soaps, soaps, facial cleansers, and softeners. Although not intended, combinations with woody, amber and floral fragrances are particularly preferred.

In the present invention, a silicone derivative can be blended with the composition which is the object of the fabric odor or flavor improving agent within a range that does not affect the fabric odor. Can be improved. Examples of such silicone derivatives include dimethylpolysiloxane, methylphenylsiloxane, methylphenylpolysiloxane, amino-modified silicone, polyether-modified silicone, fatty acid-modified silicone, fluorine-type modified silicone, cyclic silicone, alkyl-modified silicone, alcohol-modified silicone, and aliphatic. Modified silicone, epoxy-modified silicone and the like can be mentioned.

One or more silicone derivatives can be used in combination, and it is preferable to add 0.1 to 15%, particularly 0.5 to 10%, to the whole composition.

Further, a cationic polymer can be blended with the above-mentioned composition within a range that does not affect the odor of the dough, so that the slipperiness and fragrance can be improved. Examples of such a cationic polymer include a cationized cellulose derivative, a cationic starch, a cationized guar gum derivative, a diallyl quaternary ammonium salt polymer, a diallyl quaternary ammonium salt / acrylamide copolymer, and a quaternized polyvinylpyrrolidone derivative. Can be

Dyes, ultraviolet absorbers, antioxidants, antibacterial agents, preservatives, purified water, and the like can be appropriately added as long as the effects of the invention are not impaired.

In the above-mentioned composition, the pH can be adjusted to 3 to 11 by using an alkaline or acidic agent as required depending on the application. The composition improved in fragrance according to the present invention includes hair cosmetics, body soaps, soaps, facial cleansers, clothing detergents, surfactants such as softeners, etc., as long as they are perfumed. Although it can be applied to any of them, it is particularly suitably used as a hair or skin cosmetic such as a hair shampoo, a hair rinse, a hair conditioner, a hair treatment, a body soap, a soap and a face wash.
