Description

  The present invention relates to a paste-like cleaning composition excellent in stability at high temperatures, usability at low temperatures, and mildness to the skin while maintaining good foam performance of higher fatty acids.

In the cleaning agent, not only foam performance (foaming, foam volume, foam quality, foam feel, etc.), but also irritation to the skin during washing (burning feeling, tingling feeling) and skin condition after washing (no tingling feeling, tingling feeling) Excellent mildness to the skin, such as lack of sensation and lack of touch, is an important product quality that affects consumer preference.
On the other hand, in the paste-like detergent composition based on higher fatty acids and salts thereof, consumers prefer the non-nullness at the time of rinsing and the refreshing feeling after washing, but the mildness to the skin is not always satisfactory. Not a level. For this reason, in order to improve the mildness of the paste-like cleaning composition on the skin, a device such as an amino acid-based surfactant is added. However, in order to obtain sufficient mildness to the skin, if a large amount of amino acid anionic surfactant is used in combination with higher fatty acids and their salts, the crystallization temperature of the preparation will decrease, so separation, water separation, and uneven viscosity will occur. There is a problem that the stability at high temperature is significantly reduced.

  Therefore, in order to maintain mildness to the skin while ensuring stability at high temperatures, polyglycerin and polyethylene glycol are added to increase viscosity by using amino acid anionic surfactant as a basic component of the cleaning agent. A pasty detergent composition has been proposed (see Patent Documents 1 and 2 below). However, in these proposals, for example, when a cleaning agent is filled in a tube container or the like, there is a problem that it becomes difficult to take out the container at a low temperature. In addition, there is a problem that the foam performance at the time of washing is not good.

  On the other hand, for the purpose of improving usability at low temperatures and improving the mild feeling on the skin, a higher fatty acid and a stearyl ether nonionic surfactant are used in combination, and the skin has low irritation and excellent foam performance. A cleaning composition has been proposed (see Patent Document 3 below). However, in this proposal, if the content of the stearyl ether nonionic surfactant is large, the good foam performance of the higher fatty acid is remarkably lowered, and both the good foam performance and the mildness to the skin are obtained. It is difficult to obtain and difficult to apply as a paste-like cleaning composition.

  About paste-like cleaning composition of Examples 10-12, when foam performance, stability at high temperature, usability at low temperature, and mildness to skin were evaluated in the same manner as in Example 1, In this example, it was found that the foam performance was excellent, the usability at low temperatures was excellent, and the mildness to the skin was also excellent.

In addition, the compositions of Examples 1 to 12 and the paste-like cleaning compositions of Comparative Examples 1 to 9 were filled in the following containers unless otherwise specified, and it was confirmed that there was no problem in quality. It was.
Container 1: Tube (Material: innermost layer HDPE, outermost layer PP)
Container 2: Tube (material: PET), pump dispenser (material: PP, PE)
Container 3: Tube (Material: PP)
Container 4: Tube (Material: PE)
Container 5: Tube (Material: HDPE)
Container 6: Bag-shaped container (Materials: innermost layer LDPE, intermediate layer aluminum layer, outermost layer PET)
Container 7: bag-like container (materials: innermost layer LDPE, intermediate layer aluminum vapor deposition layer, outermost layer NY)
The PP represents polypropylene, the PE represents polyethylene, the PET represents polyethylene terephthalate, the HDPE represents high-density polyethylene, the LDPE represents low-density polyethylene, and the NY represents Represents nylon.

The paste-like cleaning composition of the present invention can be used not only as a normal dosage and cleaning method, but also maintains good foam performance of higher fatty acids while maintaining stability at high temperatures, usability at low temperatures, and skin. For example, it is suitably used as a cleaning agent for body washing filled in a tube.
