Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for producing a foam,
The present invention relates to a creamy detergent composition which is excellent in moist feeling and smoothness without causing a feeling of tightness on skin after use.

[0002]

2. Description of the Related Art A creamy detergent composition containing a fatty acid soap as a main component is widely used as a detergent having good foaming properties, easy rinsing, a refreshing feeling after use, and excellent usability. Furthermore, in recent years, not only detergency, but also drying and bulking after use due to excessive degreasing, for the purpose of preventing a tight feeling, various emollients and moisturizing agents have been blended, and attempts have been made to impart a moist feeling. . Various silicone derivatives and oils have been used as emollients.

[0003]

However, simply adding the conventionally proposed silicone derivative or oil agent to the cleaning agent does not sufficiently prevent the after-skin from feeling tight.
Further, in some cases, sufficient foaming may not be obtained due to inhibition of the foaming property, and the originally required cleaning effect may be impaired. Therefore, there has been a demand for the development of a creamy detergent composition which is excellent in foaming properties and cleaning effects, and which can impart a smooth feel without causing a tight feeling on the skin after use.

[0004]

Under such circumstances, the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result,
It has been found that by combining and combining specific silicone components, it is possible to obtain a creamy detergent composition that does not cause tight skin after use while maintaining sufficient detergency and usability. Reached.

That is, the present invention relates to the following components (A) and (B): (A) a partially crosslinked polyether-modified organopolysiloxane polymer and / or a partially crosslinked organopolysiloxane polymer 0.01 to 5% by weight % (B) A creamy detergent composition comprising 5 to 60% by weight of a higher fatty acid potassium salt. Further, in addition to the above-mentioned components, a polyoxyethylene alkyl ether carboxylate is added as a component (C).
It is a creamy detergent composition characterized by containing 01 to 30% by weight. The details will be described below.
