Description

[Detailed description of the invention] The present invention relates to shampoo compositions.

More specifically, the present invention relates to a Jump 1 composition that is characterized by adding a higher fatty acid salt and a phosphate ester surfactant to a Jump 1 composition based on an anionic surfactant. Conventionally used Jump compositions include anionic surfactants such as alkyl sulfate salts and polyoxyethylene alkyl sulfate salts, nonionic surfactants such as polyoxyethylene alkyl ethers and fatty acid alkylolamides, and alkyl betaines. , alkylamine oxides, and other zwitterionic surfactants are used alone or as a mixture as a Jump base, but these Jump base compositions remove excess sebum and other oils present in the hair. After washing it off, your hair feels very bad, and it becomes difficult to comb and brush through it.

Furthermore, when the hair is completely dry, it is difficult to manage, and especially in the winter when the humidity is low, static electricity is easily generated by brushing, causing phenomena such as hair flies, and the hair becomes tangled, resulting in even more combing and brushing. It has the disadvantage of making hair difficult to pass through, which eventually leads to split ends and breakage. In addition, a method of adding an oil or the like to a general Jump 1 base and supplementing the oil during hair washing is known in the prior art, and various oils are added to ordinary Jump 1. However, the amount of these oils added is limited, and of course in the Jump series they are emulsified or solubilized by surfactants, making it difficult to leave a sufficient amount of oil on the scalp and hair. It is. Furthermore, if a large amount of oil is added, the amount of oil adsorbed to the hair will increase, but the foaming and cleaning power, which are the original functions of syanbu, will be extremely impaired, and the product value will be significantly impaired. On the other hand, in recent years, many Jump compositions containing cationic polymers have been proposed for the purpose of imparting a rinsing effect to hair after washing.
It has various drawbacks as described below. For example, products that have a conditioning effect but have poor foaming and cleaning power, products that become colored or change color over time, products that have excellent foam properties but have poor conditioning effects, and products that are expensive. This is a fatal flaw. The inventors of the present invention have conducted intensive research to improve the shortcomings of conventional Jump compositions and to develop a Jump composition that has a conditioning effect that gives suppleness and smoothness to the hair after washing. Unexpectedly, anionic surfactants other than phosphate ester surfactants and higher fatty acid salts are based on Jump compositions in which higher fatty acid salts and phosphate ester surfactants are used in combination. It was discovered that it is possible to impart excellent condensing effects such as suppleness, smoothness, etc. to the hair after washing, and ease of combing without impairing the original performance of the Jump composition. completed.

That is, the present invention provides (4) 0.1 to 10% by weight of a phosphate ester surfactant represented by the general formula (4) (wherein R is k-0-X or k-CONH-X, and k has 1 to 2 carbon atoms

Repeat the washing and rinsing operation twice using Jump 1 Composition 1r, and when the hair is deflated, place it on a strain gauge and comb it with a comb, and measure the force applied at that time (when wet). Dry with a hair dryer, leave in a constant temperature and humidity room at 20°C and 65% relative humidity overnight, place on a strain gauge, and rub with a comb.
Measure the force applied at that time (during drying). (4) Observe whether or not a hair fly phenomenon occurs due to static electricity when measuring the hair fly "Kushi Dori" when it is dry.

(5) Ease of drying after washing Prepare as many hair strands (human hair) of approximately 5 tons as the number of samples, wash your hair twice with each jump composition, absorb excess moisture with a spout, and comb twice. After passing through the hair, hang the hair bundle in a room at 20°C and 65% relative humidity, and blow air with a hair dryer (20°C wind).
