Description

  The present invention relates to a liquid detergent composition that is excellent in foaming properties and refreshing feeling at the time of rinsing, does not develop stagnation or feeling of bulkiness after washing, and has excellent stability at low temperatures.

  Higher fatty acid salts have excellent detergency and foaming properties, which are basic performances of detergents, and are refreshing when rinsed, and have been widely used as a cleaning ingredient since ancient times. However, this higher fatty acid salt has a problem of causing irritation such as itching and a feeling of bulkiness to a person whose skin is sensitive. In order to solve such a problem, there has been proposed a cleaning agent for the purpose of improving mildness, which is free from stagnation and bulkiness, as described below.

  For example, an irritation reducing agent that has improved mildness by using a specific anionic surfactant has been proposed (see Patent Document 1). In addition, there has been proposed a detergent composition that combines foaming and rinsing performance with mildness by combining a specific anionic surfactant and lauric acid (see Patent Document 2). However, these proposals have a problem in that they are not yet sufficient in that they do not develop stagnation or feeling of bulkiness after washing.

  Further, there has been proposed a detergent composition that improves mildness to the skin by using a low-irritant surfactant without using a higher fatty acid salt (see Patent Document 3). However, this proposal has a problem that it is not satisfactory in terms of usability such as foaming at the time of washing, and sliminess.

  Moreover, the detergent composition which aimed at irritation | stimulation to skin by adding a higher fatty acid salt, a specific polyhydric alcohol, and charcoal is proposed (refer patent document 4). However, this proposal has a problem that it is not sufficient in that it does not exhibit stagnation or a feeling of bulkiness after washing.

  In addition, a creamy skin cleanser composition that does not contain lauric acid and suppresses irritation to the skin by using at least one of an anionic surfactant and an amphoteric surfactant has been proposed (patent) Reference 5). However, in this proposal, when a liquid cleaning agent is used, there is a problem that crystals are precipitated at a low temperature, and it is difficult to maintain stability as a product.

  Therefore, a liquid detergent composition that is excellent in foaming properties and refreshing feeling at the time of rinsing, does not develop stagnation or feeling of bulkiness after washing, and has excellent stability at low temperature has not yet been provided. The current situation is that this development is highly desired.
