Description

Technical Field

[0001] The present invention relates to a detergent composition. More specifically, it relates to a detergent composition for application to the skin, particularly the face.

[0002] Detergent compositions are roughly classified into an oil-based type with an oily external phase and an aqueous-based type with an aqueous external phase depending on the combination of components serving as the base. For example, the oil-based type mainly includes cleansing oils and water-in-oil emulsions, and the aqueous-based type mainly includes solubilized types, oil-in-water emulsions, etc.

[0003] In addition, among these detergent compositions, liquid or paste-like detergent compositions often have high detergency, good foaming during use, and good foam quality.

[0004] Conventionally, for the purpose of providing a detergent composition capable of achieving high detergency and good foaming, a detergent composition containing an anionic surfactant, an amphoteric surfactant, a hydrophilic nonionic surfactant, and an oil component has been proposed (Patent Document 1).

[0005] Also, for the purpose of providing an oil-based cleaning agent capable of exhibiting an excellent cleaning effect, an oil-based cleaning agent containing a nonionic surfactant with an HLB of 9 to 16, a liquid oil component, and propylene glycol laurate has been proposed (Patent Document 2).

[0006] Furthermore, due to the diversification of current consumers' needs, the market demand for a detergent composition that can not only provide rich foaming during use and good foam quality but also improve the skin condition after washing is increasing.

Summary of the Invention

Problems to be Solved by the Invention

[0008] However, the composition of Patent Document 1 may result in insufficient moisturizing feeling of the skin after drying due to excessive degreasing. It was difficult for the composition of Patent Document 2 to achieve both a non-greasy feeling of the skin after washing and a moisturizing feeling obtained after washing.

[0009] Therefore, there has been a demand for a detergent composition that not only has good foaming properties, but also provides a moist feeling immediately after rinsing and maintains the moist feeling even after rinsing, while being non-greasy.

Means for Solving the Problems

[0010] As a result of intensive studies to solve the above problems, the present inventors have found that the above problems can be solved by using a detergent composition containing (A) an anionic surfactant, (B) an amphoteric surfactant, and (C) propylene glycol laurate, and have thus completed the present invention.
