Description

Description: TECHNICAL FIELD The present invention relates to a shampoo composition, and more particularly to a shampoo composition that imparts a rinsing effect at the same time as shampooing and provides an excellent conditioning effect.

[Prior art / problems] Until recently, desirable properties of a shampoo or a rinse for hair were exhibited by using a shampoo composition and a rinse composition separately, and the use of a single composition resulted in such properties. Both functions could not be performed.

In recent years, as a shampoo composition having a conditioning property or a rinsing effect, a two-layer separation type shampoo,
Oil-containing shampoos, silicon derivative-containing shampoos, and cationic surfactant-containing shampoos are known.

However, these shampoo compositions do not exhibit sufficient rinsing properties for hair, ie, less squeaking during rinsing, hair styling properties (flexibility, good slipping properties, good combability), and their foaming properties Power is not enough.

Therefore, an object of the present invention is to provide hair with sufficient rinsing properties, that is, less squeak during rinsing and good hair styling properties,
An object of the present invention is to provide a shampoo composition having sufficient foaming power.

[Means for Solving the Problems] As a result of intensive studies on these problems, the present inventors have reached the present invention.

That is, the present invention provides (I) one or two or more anionic surfactants selected from alkyl sulfates or salts thereof and soaps; [Wherein, R ₁ , R ₂ and R ₃ each represent an alkyl group having 1 to 3 carbon atoms, which may be the same or different, and a +
b = 5 to 50 and a = 0 to 3; a / (a + b) <0.2
The polyether type quaternary ammonium salt represented by the formula (1), and the amount of (II) relative to 1 part by weight of (I) is 0.
003 to 0.2 part by weight, according to the composition for shampoo.

[Action] The anionic surfactant (I) used in the present invention is not particularly limited as long as it can be blended into the shampoo composition, but the preferred structure is as follows.

(1) Alkyl sulfate (salt) R-OSO ₃ M In the formula, R represents an alkyl group having 8 to 18 carbon atoms, and M is selected from a hydrogen ion, an alkali metal ion, an ammonium ion, and an alkanolamine ion.

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

These anionic surfactants (I) can be used alone or in a suitable mixture.

The polyether quaternary ammonium salt (II) used in the present invention has the general formula [Wherein, R ₁ , R ₂ and R ₃ each represent an alkyl group having 1 to 3 carbon atoms, which may be the same or different, and a +
b = 5 to 50 and a = 0 to 3; a / (a + b) <0.2
For example, oxyethylene polyoxypropylene methyl diethylammonium chloride, polyoxypropylene methyl diethylammonium chloride, oxyethylene polyoxypropylene dimethylpropylammonium chloride, polyoxypropylene trimethylammonium chloride, oxyethylene chloride Examples thereof include polyoxypropylene methyl ethyl propyl ammonium. In the above general formula, when a + b is less than 5, the finish feeling is poor, and when a + b is more than 50, the product stability such as sedimentation and separation deteriorates. a exceeds 3 or a / (a + b) is 0.
If it is 2 or more, the finish feeling will be poor, and the conditioning property will also be reduced.

The polyether-type quaternary ammonium salt (II) used in the present invention is 0.003 to 02 parts by weight, preferably 0.01 to 0.2 parts by weight, per part by weight of the anionic surfactant (I).

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

The shampoo composition of the present invention can be a good shampoo composition by adding water to an appropriate concentration.
Preferably in the shampoo composition (I) and (II)
Is preferably used so that the total amount thereof is 1 to 40% by weight, more preferably 5 to 30% by weight.

If the amount of the composition for shampoo of the present invention is less than the above, the effect may not be sufficiently exhibited, and even if used in excess of the above amount, not only is it uneconomical, but sometimes it becomes difficult to form an aqueous solution, If the amount of the anionic surfactant is too large, the low-temperature stability may deteriorate, which is not preferable.

To the shampoo composition using the shampoo composition of the present invention, commonly used auxiliary additives can be added as needed depending on the purpose of use and the like, as long as the effects of the present invention are not affected.

Such auxiliary additives include, for example, salt, sodium sulfate,
Solubilizers, antioxidants such as dibutylhydroxytoluene, α-tocopherol, ultraviolet absorbers, protein derivatives,
Animal and plant extracts, fungicides, pigments, fragrances and the like can be mentioned.

Further, for the purpose of adjusting the detergency and foaming property of the shampoo composition using the shampoo composition of the present invention, other surfactants other than those described above are appropriately added as long as the effects of the present invention are not impaired. be able to.

As these surfactants, nonionic surfactants such as fatty acid diethanolamide, amphoteric surfactants such as betaine type and imidazoline type, homopolymers or copolymers of dialkyldiallylammonium salts and cationized polymers such as cationized cellulose, Cationic surfactants such as dialkyldimethylammonium salts and alkyltrimethylammonium salts, and silicon compounds are exemplified.
