Description

[Technical Field]

[0001] The present invention relates to a detergent having excellent detergency against triglycerides. [Background technology]

[0002] Human scalp sebum is made up of triglycerides, free fatty acids, squalene, wax esters, etc. It is composed of approximately 40% of triglycerides, which are the main components. It has been reported (Non-Patent Document 1). Sebum covers the surface of the skin and prevents the intrusion of foreign substances from the outside. It plays a physiological role in preventing excess secretion of skin oils and preventing water leakage from the body. Oil can cause various scalp problems (bad odor, dandruff, stickiness, inflammation, etc.). In recent years, with the increasing trend of people becoming more conscious of cleanliness, hair cleansers (such as shampoos) with excellent sebum-cleansing properties have become increasingly popular. Daily care is required.

[0003] Surfactants are essential ingredients for hair cleansers to have a cleansing effect on sebum stains. Examples of the cleaning mechanisms of surfactants include rolling up, emulsification, and solubilization. Solubilization is involved in the cleaning mechanism of hair cleansing agents such as shampoo, and other mechanisms are involved. Therefore, in order to effectively remove sebum stains, To achieve this, it is necessary to add a sufficient amount of surfactant to solubilize the sebum components. However, excessive use of surfactants can wash away the intercellular lipids that are responsible for the skin's natural barrier function, leading to poor health. From the above perspective, even a small amount can be used to sufficiently remove sebum stains. It has excellent cleaning power against sebum stains (especially triglycerides, which are its main component) so that It is necessary to select a cleaning agent that is suitable for the purpose, but such research has not yet been sufficient.

[0020] The present invention will be explained in more detail below with reference to examples, comparative examples and test examples. The present invention is not limited in any way by these examples. Represents "mass %."

[0021] (Test Example 1) The solubility limit concentration of various components is measured for triolein, a type of triglyceride. The cleaning power was evaluated by this test.

[0022] Purified water, triolein, and the various components listed in Table 1 were added at a final concentration of 1%. The solution was weighed to a concentration of 0.1 to 0.001%, and 10 g of mixed aqueous solutions of various concentrations were prepared. The mixture was shaken at room temperature for 1 hour, then left to stand overnight at room temperature. The surface activity of each sample was measured using a UV-visible spectrophotometer (UV-2450, Shimadzu Corporation). The absorbance at 600 nm of the aqueous solution of the activator / triolein mixture was measured as turbidity. The turbidity value is plotted against the concentration of ethanol, and the point where the turbidity begins to increase rapidly (inflection point) is determined. The triolein concentration obtained was calculated as the triolein solubilization limit concentration.

[0023] (Test results) Those with a triolein solubilization limit concentration of 0.001% or more were considered to have excellent cleaning power (○). The results of the evaluation are shown in Table 1. .

[0024] [Table 1]

[0025] Examples 1 to 3 are made of polyoxyethylene fatty acid glyceryl or alkyl glucoside. It has a high triolein solubilization limit concentration and excellent cleaning power against triolein. On the other hand, in Comparative Examples 1 to 16 in which other ingredients were used, the triolein solubilization limit was It was found that the concentration was low and the cleaning power against triolein was insufficient.

[0026] (Test Example 2) By measuring the solubilization limit concentration when various ingredients are combined, we can evaluate the effect of improving cleaning power. went.

[0027] Purified water, triolein, polyoxyethylene (caprylic / capric acid) glyceryl and The various components listed in Table 2 were added at the final concentrations listed in Table 2, and the final triolein concentration was 0.07 to 0.0 The mixture was weighed out so that the concentration was 0.1%, and 10 g of mixed aqueous solutions of various concentrations were prepared. The mixture was shaken and then left to stand overnight at room temperature. After mixing by inversion, the mixture was left to stand for at least one more hour (to degas). , polyoxyethylene (capsules) was measured using an ultraviolet-visible spectrophotometer (UV-2450, Shimadzu Corporation). The absorbance at 600 nm of a mixed aqueous solution of glyceryl (glyceryl / caprate) / triolein was measured as a turbidity index. The turbidity values ​​were plotted against the triolein concentration, and the turbidity increased rapidly. The triolein concentration at the point where the inflection point begins is calculated as the triolein solubilization limit concentration. did.

[0028] (Test results) Compared with Example 2, the improvement rate of the triolein solubilization limit concentration was 10% or more. Combinations with excellent detergency improvement effect (○), those with an improvement rate of 0 to less than 10% were considered to have improved detergency. Combinations with insufficient effect (△), and combinations with negative improvement rates are those with no effect on improving cleaning power. The evaluation results are shown in Table 2.

[0029] [Table 2]

[0030] In Examples 4 to 7, the triolein solubilization limit concentration was dramatically improved compared to Example 2, and the washing On the other hand, the comparative example in which other ingredients were combined Combinations 17 to 20 do not improve the triolein solubilization limit concentration and are insufficient in improving cleaning power. Therefore, it was found that polyoxyethylene (capryl / capric Glyceryl acetate, taurine, coptis extract, Phellodendron bark extract, and Tencha extract It has been revealed that the combination of ingredients selected from the above ingredients is an excellent cleanser for the scalp or hair. It became like this. [Industrial Applicability]

[0031] This invention provides excellent cleansing power against triglycerides, the main component of sebum stains on the scalp. It has become possible to provide a cleaning agent having the above properties.
