Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a detergent composition, such as a hair detergent and a clothing detergent, which has both a cleaning effect and a finishing effect.

[Conventional technology]

Up until now, cleaning agents and finishing agents have been used separately in order to wash hair and clothing, but in recent years various proposals have been made to obtain cleaning agents that have both cleaning and finishing effects. is being done. Many of these proposals attempt to obtain both a cleaning effect and a finishing effect by adding a specific ingredient that has a finishing effect to the cleaning agent. Moisturizing agents such as silicone derivatives, water-soluble glyceride derivatives, propylene glycol, glycerin, and ethylene glycol, as well as hydrocarbon oils and silicone oils (Japanese Patent Application Laid-Open No. 61-210022), are known, and softeners and Quaternary ammonium salt as a rinse base, nonionic surfactant (Japanese Patent Application Laid-Open No. 53-13320
No. 6), amphoteric surfactant (JP-A-50-23407)
, specific anionic surfactants (JP-A-52-35203
No.), specific cationic surfactants (Japanese Patent Publication No. 47-478
No. 45) is also known to be used. Also, U.S. Patent No. 34
, No. 7284.0 describes that shampoos formulated with polymer JR resin, which is a cationic cellulosic resin, have desirable properties as both a shampoo and a conditioner.

[Problem to be solved by the invention]

As mentioned above, with the increasing awareness of hair care, recent shampoos are required to not only have good cleansing power, but also have excellent effects on the feel and texture of the hair during washing. It is desired that hair does not get tangled with each other in the comb, and that the hair can be combed smoothly without getting tangled with each other during combing. I haven't been able to find anything that fully satisfies my points. In particular, there are detergents that contain oils and other ingredients on the market to give hair a finishing effect, but because the oils are mixed into the water system, they are difficult to dissolve and are extremely unstable. It is.

In addition, regarding cleaning agents, we use conventional cleaning agents,
If a soft anti-static effect imparting agent is not used in combination, the fabric is likely to be damaged by use of a dryer and may become electrostatically charged after finishing.Therefore, there is a strong demand for a cleaning agent that imparts softness and anti-static effect during finishing at the same time as washing. However, a cleaning agent that can solve these problems has not yet been developed.

In this way, conventional cleaning agents that have been proposed for the purpose of imparting cleaning and finishing effects have a
There were problems with the dispersion stability of finishing additives, finishing effects, etc.

The present invention was developed in view of the above circumstances, and provides an excellent feel during use, and when finished, provides smoothness and softness to hair and clothing, as well as a streetcar prevention effect, as well as dispersion of poorly water-soluble oils. The purpose of the present invention is to provide a cleaning composition with excellent stability.

[Means and effects for solving the problem] In order to achieve the above object, the present invention contains 5 to 30% by weight of a surfactant, 0.01 to 10% by weight of a poorly water-soluble oil, and the following formula (I):
The acrylic resin represented by (II) or (III) was added to 0.
Provided is a cleaning composition characterized by containing 1 to 5% by weight.

5 (However, in the formula, X and Y are each a hydrogen atom, an alkali metal, an ammonium group, an alkanolamine residue, or an alkyl group having 1 to 4 carbon atoms, P = 100 to 20,000, Q =
It is 100-20000. ) That is, in the present invention, a surfactant, a poorly water-soluble oil, and (1) to (III)
By using the acrylic resin represented by the formula in a specific ratio, these three components act synergistically, providing an excellent rinsing feel during washing, and leaving hair and clothing with a smooth, soft texture and static electricity when finished. It was possible to obtain a detergent composition that not only provides a detergent effect but also has excellent dispersion stability of poorly water-soluble oil components. In this case, the cleaning composition of the present invention forms a film on the surface of the object to be cleaned using the poorly water-soluble oil and the acrylic resin, and exhibits an excellent finishing effect.

The present invention will be explained in more detail below.

As described above, the cleaning composition of the present invention contains a surfactant, a poorly water-soluble oil component, and an acrylic resin of formulas (I) to (III) in specific amounts.

If it is less than -% by weight, not only will the poorly water-soluble oil not be stably blended, but it will also be difficult to adsorb the poorly water-soluble oil to the object being cleaned, and it will also be difficult to form a film, resulting in poor softness in the finished product. It is not possible to impart sufficient smoothness. Moreover, if it exceeds 5% by weight, the object to be cleaned will become sticky when finished, and the effect on stable formulation will not increase, so it is economically meaningless.

The detergent composition of the present invention is prepared as a shampoo for hair, a detergent for clothing, etc. In this case, the detergent composition of the present invention may contain the following ingredients to the extent that the effects of the invention are not affected. If necessary, commonly used auxiliary additives can be added.

Examples of such additives include common salt, mirabilite, solubilizers, antioxidants such as BTH5α-tocopherol, ultraviolet absorbers, protein inducers, animal extracts, preservatives, bactericidal agents, pearlescent agents, and milk. Examples include clouding agents, antidandruff agents, tonic agents, pH adjusters, pigments, fragrances, cationic polymer conditioning agents, and the like.

〔Effect of the invention〕

As explained above, the cleaning composition of the present invention not only provides a good feel during cleaning, but also can impart smoothness and softness to items to be cleaned, such as hair and clothing, after finishing. Because it can leave an appropriate amount of moisture and oil on the
