Abstract

PURPOSE:To obtain a composition for shampoo to simultaneously provide hair washing effects and rising effects by blending an nonionic surfactant selected from an alkyl sulfate, a salt thereof and soap with aspecific polyether type quaternary ammonium salt in a fixed ratio. CONSTITUTION:One or more nonionic surfactants selected from an alkyl sulfate, a salt thereof and soap are blended with a polyether type quaternary ammonium salt shown by the formula [R1 to R3 are 1-3C alkyl; a+b is 5-50, a=0-3 and a/(a+b) is <0.2] in a ratio of 0.003-0.2 pt.wt., preferably 0.01-0.2 pt.wt. compound shown by the formula to 1 pt.wt. of the surfactant to give a composition for shampoo. The composition provides the hair with sufficiently rinsing characteristics, especially slight displeasure, excellent hair dressing and has sufficient foaming power.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a shampoo composition, and more particularly to a shampoo composition that imparts a shampooing effect, especially a rinsing effect, and provides an excellent conditioning effect.

1. Prior Art/Problems 1 Until recently, the desirable properties of hair shampoos and hair conditioners were achieved by using a shampoo composition and a conditioner composition separately, and they were not achieved by using a single composition. It was not possible to perform both functions.

In recent years, two-layer separation type shampoos, oil-containing shampoos, silicone derivative-containing shampoos, and cationic surfactant-containing shampoos have become known as shampoo compositions that have conditioning or rinsing effects.7 However, these shampoo compositions The products do not exhibit sufficient rinsing properties for hair, that is, little frizz during rinsing, and hair styling properties (softness, good slipperiness, and good hair-flowing properties), and their foaming power is also not sufficient.

Accordingly, an object of the present invention is to provide a shampoo composition that has sufficient rinsing properties for the hair, that is, less frizz during rinsing, provides good hair styling properties, and has sufficient foaming power.

[Means for Solving the Problems] As a result of intensive research into these problems, the present inventors found that
We have arrived at the present invention.

That is, the present invention provides (II) one or more anionic surfactants selected from alkyl sulfates or their salts and soaps, and (II) general represents an alkyl group of numbers 1 to 3, which may be the same or different, a+b=5 to 50 and a=0 to 3, a/(a
+b) contains a polyether type quaternary ammonium salt represented by 1 with <0.2, and the amount of (II) is 0.003 to 0.2 parts by weight per 1 part by weight of (I) The present invention relates to a shampoo composition characterized in that:

[Function] The above-mentioned anionic surfactant (II) used in the present invention is not particularly limited as long as it can be blended into a shampoo composition, but a preferred structure is as follows.

(II) Alkyl sulfuric acid (salt) R-O20,M In the formula, R represents an alkyl group having 8 to 18 carbon atoms, and M represents a hydrogen ion, an alkali metal ion, an ammonium ion,
From alkanolamine ion; wing root.

(2) Soap fl-COOM In the formula, R is an alkyl group having an average carbon number of 10 to 24, and M is selected from a hydrogen ion, an alkali metal ion, an ammonium ion, and an alkanolamine ion.

These anionic surfactants (II) can be used alone or in an appropriate mixture.

Polyether quaternary ammonium salt used in the present invention (
II) refers to general 2 [wherein R5, R2, and R1 each represent an alkyl group having 1 to 3 carbon atoms, and may be the same or different, a+b=5 to 50 and a-0 ~3 and a/(a+
b)<0.2] For example, oxyethylene polyoxypropylene methyl diethylammonium chloride, polyoxypropylene methyl diethylammonium chloride, oxyethylene polyoxypropylene dimethyl bropylammonium chloride, polyoxy chloride Examples include propylene trimethyl ammonium, oxyethylene polyoxypropylene methylethylbropylammonium chloride, and the like. In the above general 2, if a+b is less than 5, the finished texture will be poor, and if it exceeds 50, product stability such as precipitation and separation will be poor. If a exceeds 3 or a/ (a +
If b) is 0.2 or more, the finished texture will be poor and the conditioning properties will also be reduced.

The polyether type quaternary ammonium salt (II) used in the present invention is 0.003 to 0.2 parts by weight, preferably 0.01 parts by weight, per 1 part by weight of the anionic surfactant (II).
~082 parts by weight.

When the number of polyether-type quaternary ammonium salt (II) cavities exceeds the above range, that is, when the proportion of anionic surfactant is low, foaming becomes poor.

The shampoo composition of the present invention can be made into a good shampoo composition by adding water to an appropriate concentration, and preferably contains the above-mentioned components <1) and (II).
They may be used so that the total amount is 1 to 40% by weight, more preferably 5 to 30% by weight.

If the amount of the shampoo composition of the present invention used is less than the above, the effect may not be sufficiently exhibited, and if it is used in excess of the above amount, it may not only be uneconomical but also difficult to form an aqueous solution. Too much anionic surfactant is not preferred because low temperature stability may deteriorate.

To the shampoo composition using the shampoo composition of the present invention, commonly used auxiliary additives may be added as necessary depending on the intended use within a range that does not affect the effects of the present invention.

Examples of such auxiliary additives include salt, mirabilite, solubilizers, dibutylhydroxytoluene, antioxidants such as α-tocopherol, ultraviolet absorbers, protein derivatives, animal and plant extracts, fungicides, pigments, fragrances, etc. be able to.

Furthermore, the shampoo composition using the shampoo composition of the present invention may contain, for the purpose of adjusting cleansing properties, foaming properties, etc.
Other surfactants other than those mentioned above may be added as appropriate within a range that does not impair the effects of the present invention.

These surfactants include nonionic surfactants such as fatty acid jetanolamide, amphoteric surfactants such as betaine type and imidacilline type, pomopolymers or copolymers of dialkyl diallylammonium salts, and cationized polymers such as cationized cellulose. , cationic surfactants such as dialkyldimethylammonium salts and alkyltrimethylammonium salts, and silicon compounds are prohibited.
