Description

TECHNICAL FIELD OF THE INVENTION The present invention provides a smooth and slippery foamy feel at the time of washing hair, gives a smooth and smooth finger passage to the hair at the time of rinsing, and at the same time makes the hair smooth at the time of finishing. The present invention relates to a shampoo composition that gives good gloss.

Problems to be Solved by Conventional Techniques and Inventions In recent years, the aesthetic sense of hair has been raised, and the number of chemical treatments such as permanent wave, hair dye, hair bleach, etc. for hair and the number of times of hair washing, and further hair using a dryer, a brush, etc. The number of times of care is increased and the hair is easily damaged. Therefore, as a function of the shampoo composition,
Not only a cleansing and foaming property, it also improves the finger passage of the hair during washing and rinsing, and prevents the damage of the hair such as the cuticle falling off due to friction, giving a healthy and natural luster to the hair. Is required. Especially regarding the foam when washing hair, it is desirable that it is not only finely detailed, but also that it is slippery and has good slipperiness.
There is a need for a shampoo composition that not only has no squeaky hair, but also has very smooth and heavy finger passage, and imparts a smooth feel to the hair.

Therefore, polymer JR-40 has been conventionally used in shampoo compositions.
Cationized cellulose such as 0 (manufactured by Union Carbide Co.) is blended to enhance the conditioning effect of the shampoo composition.

However, when cationized cellulose is added to the shampoo composition, the effect of suppressing the squeaking of the hair during rinsing is excellent, but the residual feeling is strong, and a slimy or heavy feel is given. Moreover, although it gives a slight creamy feeling to the foam when washing hair, it is completely inferior to the point that it gives smooth smoothness, and it does not have the effect of giving gloss to the hair at the time of finishing. There's a problem.

On the other hand, a shampoo was blended with a copolymer of dimethyldiallylammonium halide and acryloamide (Merck, MERQUAT 550, etc.), which has excellent film forming properties,
Although it has been attempted to enhance the conditioning effect, a shampoo composition containing an anionic surfactant as a main component has a low residual property on hair and an effect of suppressing squeaking of hair during rinsing is insufficient. Also, it gives a very rich foaming and creamy feeling to the foam when washing hair, but has not yet reached a smooth and smooth foam feeling.

As described above, a shampoo composition having a sufficient conditioning effect in a comprehensive sense from the time of washing the hair to the time of rinsing and finishing has not been heretofore obtained, and therefore, a shampoo composition having an excellent conditioning effect is comprehensively obtained. There has been a desire to develop quality shampoo compositions.

The present invention has been made in view of the above circumstances, and gives a smooth foamy feel to the hands when washing hair, and gives a smooth and smooth finger passage to the hair during rinsing.
Moreover, it is an object of the present invention to provide a shampoo composition that gives gloss to hair when finished.

Means and Actions for Solving Problems The present inventors have conducted extensive studies in order to achieve the above-mentioned object, and as a result, use a copolymer of a dialkyldiallylammonium salt and cationized cellulose in combination, particularly a weight ratio of both components. When used in combination at a ratio of 1/10 to 10/1, both of these components act synergistically to give a smooth foam feel on the fingers that was smooth when washing hair, and also to the hair when rinsing. It was found that a shampoo composition that gives a smooth finger passage and has a good overall conditioning effect that gives good gloss to the finished hair can be obtained, and completed the present invention.

Therefore, the present invention provides a shampoo composition comprising a copolymer of dialkyldiallylammonium salt and cationized cellulose.

 Hereinafter, the present invention will be described in more detail.

The first essential ingredient of the shampoo composition of the present invention is a copolymer of dialkyldiallylammonium salts.

In addition, among the cationized celluloses represented by the above formula (III), polymer JR-400 (manufactured by Union Carbide Co.) is particularly preferably used.

In the shampoo composition of the present invention, it is preferable to blend the copolymer of the first component, the dialkyldiallylammonium salt, and the cationized cellulose, the second component, in a weight ratio of 1/10 to 10/1. The amounts of both components to be blended are variously selected, but it is preferable to blend 0.1 to 1% by weight of the copolymer of dialkyldiallylammonium salt and 0.05 to 1% by weight of the cationized cellulose. If the blending amount of both components is less than the above range, it may be slippery during hair washing and may not give a smooth foam feeling on the fingers, and it may be smooth on the fingers during rinsing and good for finishing hair. It may not be possible to give enough. On the other hand, if the amount is more than the above range, the foam viscosity is remarkably increased, and the foam may be heavy to the touch, and the smoothness of slipperiness may be reduced. , The hair may feel heavy, and you may not be able to get a smooth feel of your fingers.

The shampoo composition of the present invention, in addition to the above essential components,
Appropriate components may be added depending on the type of composition and purpose of use, but it is particularly preferable to add anionic surface active agents as the main component. When an anionic surfactant is added to the composition of the present invention, the first component and the second component respectively form a complex with the anionic surfactant, and the interaction of the complex causes an appropriate viscosity and elasticity for foam during hair washing. It gives a smooth and slippery foamy feel, and the adhesion to hair during rinsing and the film forming property are improved, so that it is possible to obtain a smooth and smooth finger passage without being heavy. At the time of finishing, good gloss can be obtained by the adsorption film of these complexes formed on the hair surface.

As the anionic surfactant, various selections are made, among which polyoxyethylene alkyl ether sulfate and alpha olefin sulfonate are preferably used,
The compounding amount thereof is usually 2 to 30% by weight based on the whole composition.

Furthermore, as other optional components, various surfactants such as nonionic surfactants, amphoteric surfactants, cationic surfactants, etc., which are commonly used components for shampoo compositions, thickeners, ultraviolet absorbers, preservatives, bactericides, One or more kinds of emulsions, antidandruff agents, antioxidants, tonic agents, pigments, fragrances and the like can be added.

Effects of the Invention As described above, the shampoo composition of the present invention comprises:
Gives a smooth and slippery foamy feel when washing hair, and gives the hair during rinsing smooth and smooth finger passage,
Moreover, it gives good gloss to the hair at the time of finishing, exerts a comprehensive conditioning effect from washing to finishing, and can sufficiently meet the needs of modern consumers.
