Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improved liquid shampoo compositions.

Conventionally, the first liquid for cold waves contains a mercapto compound with an unpleasant odor as a main ingredient, so even if you wash your hair after cold wave treatment, the unpleasant odor remains and it is difficult to remove the odor, so fragrances are not used. A commonly used method is to confuse the

In addition, removers and hair washes have been proposed for the purpose of removing the unpleasant odor, but none have been satisfactory yet. Normally, when hair is not washed for a long period of time, a large amount of unpleasant odor secretions from the scalp adhere to the hair, and in many cases, the odor cannot be removed without shampooing or washing the hair multiple times.

On the other hand, it is well known that when the water used for washing hair is highly hard, scum tends to form during shampooing, making it difficult to wash the hair smoothly.

Furthermore, various additives have been incorporated into hair products such as hair rinses and hair creams used after shampooing to improve combability, but these methods are insufficiently effective. A liquid medicine shampoo containing a quaternary ammonium salt dissolved in an aqueous solution of an anion activator such as a higher alcohol sulfate ester salt, a higher alcohol polyglycol ester sulfate ester salt, or an alkyl or allyl polyglycol ether sulfate ester salt. is already known.

However, these products are not necessarily satisfactory in terms of cleaning power and foaming properties. In addition, when higher fatty salts are used as anionic activators to improve detergency and foaming, precipitation occurs when left for a long period of time, reducing the detergency and foaming of soap and the hair softening effect of quaternary ammonium salts. This is not desirable because it will disappear. The purpose of the present invention is to provide excellent hair deodorizing effect, combability, detergency, softening effect, and dandruff prevention effect without irritating the skin.
An object of the present invention is to provide a liquid shampoo composition having good storage stability.

That is, the present invention contains 1 to 30% by weight of naturally produced aluminosilicate zeolite fine particles (weight% is based on the weight of the composition, the same applies hereinafter) and 0.5 to 30% of a water-soluble nonionic polymer.
4% by weight, according to the following general formula (in the above formula, R is an alkyl group or alkenyl group having 6 to 17 carbon atoms, and w is a benzyl group).

) 0.1-2% by weight of quaternary ammonium salt, 0.1-2% by weight of common salt, 10-30% by weight of higher fatty acid potassium salt, 1-10% by weight of higher fatty acid diethanolamide. and a liquid jump composition comprising 31 to 86% by weight of water. The embodiment will be described below.

The fine particles of naturally produced aluminosilicate zeolite used in the present invention include borosodite group, sulfite group,
Fine particles of aluminosilicate zeolites of the sodalite group are preferred.

Further, the aluminosilicate can be represented by the following general formula. (RO)WC/V(2203)X(SiO2)
Y(H2O)Z (In the formula, R is mainly an alkali or alkaline earth metal, and W, X, Y, and Z are positive integers.) The structure of zeolite is one SiO4 tetrahedron and one AlO4 tetrahedron. It is a network of covalently bonded oxygen atoms. A
Since the l atom is trivalent, the AlO4 tetrahedron has a charge of 1, and a corresponding number of metal dications are bonded thereto. Although alkali metals and alkaline earth metals are included as cations, these ions can be easily exchanged with other ions in an aqueous solution. The zeolite fine particles used in the present invention preferably have a maximum particle size of 10 microns or less and an average particle size of 2 microns or less.

(The particle size of zeolite referred to here is the average particle size determined from the sedimentation particle size distribution of fine zeolite particles separated by SHICH (hydraulic classification).

)5 When the maximum particle size is larger than 10 microns and/or when the average particle size is larger than 2 microns, the deodorizing effect, storage stability, cleansability, and hair flexibility tend to deteriorate.
The amount of zeolite fine particles blended is 1 to 30% by weight, preferably 3 to 20% by weight, based on the weight of the composition.

If it is less than 1% by weight, the odor of raw materials such as oils and fats present in the formulation, deodorizing effect on hair odor, combability, storage stability, washability, hair flexibility, foaming power, etc. will decrease, and If the amount exceeds 1% by weight, storage stability, foaming power, deodorizing effect, and hair flexibility will deteriorate, which is undesirable.

Examples of water-soluble nonionic polymers used in the present invention include polyvinyl alcohol, methyl/ethyl cellulose, polyvinyl methyl ether, polyvinyl pyrrolidone, hydroxyethyl cellulose, hydroxymethyl cellulose, hydroxypropyl cellulose, dextrin, gelatin, Examples include pectin.

These materials may be used alone or in combination. The amount used (blended amount) is 0.5 based on the weight of the composition.
-4% by weight, preferably 1-2.5% by weight. 0.
If it is less than 5% by weight or more than 4% by weight, the deodorizing effect, storage stability, combability, flexibility, foaming power, detergency, etc. will deteriorate.

If a cationic polymer electrolyte is used instead of the nonionic polymer of the present invention, the zeolite fine particles will aggregate and become huge, and may also gel, resulting in significant deterioration in storage stability and combability. However, the specificity of the action and effect of nonionic polymers is remarkable.

The specific quaternary ammonium salts used in the present invention are represented by the above general formula, and may be used singly or in combination of two or more.

The blending amount is 0.1 to 2.0% by weight based on the weight of the composition.
, preferably 0.2 to 1.0% by weight. If it is less than 0.1% by weight, it will not have the effect of softening the hair, and the combability and bactericidal effect will tend to be poor, and if it is more than 20% by weight, it will be highly irritating.

Also, the bubble power is reduced. Particularly preferred among the quaternary ammonium salts represented by the above general formula are lauryldimethylbenzylammonium chloride, octyldimethylbenzylammonium chloride, and the like.

The amount of salt added is 0.1 to 2.0% by weight, preferably 0.2 to 1.0% by weight, based on the weight of the composition. 0.1
If the amount is less than 1% by weight, the quaternary ammonium salt will precipitate and will not have the effect of softening hair, and the bactericidal power will decrease.

If the amount exceeds 2.0% by weight, the higher fatty acid potassium salt tends to be easily salted out.

The higher fatty acid potassium salt is a potassium salt of a saturated or unsaturated fatty acid having 10 to 18 carbon atoms, preferably potassium caprate, potassium laurate, potassium myristate, potassium palmitate, and potassium stearate. , potassium oleate, potassium a fatty acid, etc., and one or more of them may be used as a mixture (also a mixture). The blending amount of fatty acid potassium salt is 10 to 10% based on the weight of the composition.
30% by weight, preferably 15-28% by weight. 10
When the amount is less than % by weight, foaming becomes poor and detergency also decreases.

If the amount exceeds 30% by weight, the liquified state cannot be maintained,
Storage stability may deteriorate.

Higher fatty acid diethanolamide has 8 to 1 carbon atoms.
Diethanolamides of saturated or unsaturated fatty acids of No. 8, such as trifurylic acid diethanolamide, chipuric acid diethanolamide, lauric acid diethanolamide,
Examples include myristic acid diethanolamide, undecylenic acid diethanolamide, palmitic acid diethanolamide, stearic acid diethanolamide, oleic acid diethanolamide, and fatty acid diethanolamide.

These higher fatty acid diethanolamides are one or two types.
It is possible to use a mixture of two or more species (or a mixture). The amount of higher fatty acid diethanolamide used (blended amount) is 1 to 10% by weight, preferably 2 to 8% by weight, based on the weight of the composition.

When the amount is less than 1% by weight, the viscosity decreases, stability deteriorates, and foaming power also decreases. In addition, the amount of water blended is usually 31 to 86% by weight, preferably 50 to 7% by weight based on the weight of the composition.
It is 5% by weight. If it is less than 31% by weight, it tends to become less stable and mellow under low temperatures such as winter, and if it is less than 86% by weight.
If the amount exceeds , stability tends to decrease at high temperatures such as in summer.

Incidentally, the composition of the present invention may contain additives such as fragrances, coloring agents, preservatives, etc., which are usually necessary for jump products. The liquid jump composition of the present invention does not generate scum even when jumping using highly hard water, and eliminates the unpleasant odor of hair after cold wave treatment and the odor of hair contaminated with scalp secretions. It is easy to remove, reduces the friction coefficient of the hair, improves combability, has excellent detergency, softening effect, anti-dandruff effect, excellent storage stability, and does not irritate the skin. It is of extremely high quality and value.
