Description

  The present invention relates to a detergent composition containing polyoxyethylene alkyl ether sulfate or alkyl sulfate, which is improved in foam quality and excellent in stability.

  Various detergents are used in the cleaning composition depending on the purpose, but many of them have poor foam properties and lack elasticity. A widely used detergent composition containing polyoxyethylene alkyl ether sulfate or alkyl sulfate is an excellent detergent composition in that it is excellent in foaming and hardly affected by water quality, but has a fine particle size. The soap-based cleaning composition, which is a firm and creamy cleaning composition, is inferior in foam quality. As described above, if the foam quality of the polyoxyethylene alkyl ether sulfate or alkyl sulfate, which has a rough foam quality and lacks elasticity, can be improved to be creamy, and a detergent composition having excellent storage stability can be obtained, it is various. It is useful as a cleansing composition, especially as a body cleansing agent such as skin or hair, which is particularly creamy and has a preferred foam quality.

There is a disclosure that excellent low-temperature stability is good. Patent Document 2 discloses that an anionic surfactant having a sulfuric acid residue, a higher alcohol having a carbon number of 10 to 14 and a cationic polymer have good foaming properties and good foam quality during hair washing. There is a disclosure that it has a smooth feel at the time of rinsing and is excellent in use feeling. Patent Document 3 contains an anionic surfactant, a specific nonionic surfactant, and water, and the detergent composition exhibiting a gel or liquid crystal state has a high viscosity and droops when taken into a hand or a tool. There is a disclosure that it is good in terms of stretchability at the time of use, high storage stability, and good foaming while being hard. In Patent Document 4, a hair cleanser containing a sulfate-type surfactant, alkyl glyceryl ether, silicone oil, cationic polymer and myristyl alcohol provides good foaming and slippery foam quality and is smooth when rinsed. There is a disclosure that it has a touch, gives gloss to the finished hair, has low temperature stability, and is hypoallergenic.

A solvent is preferably used during the production, and water is preferred as the solvent.

  Hereinafter, an example is given and it demonstrates in detail.

Examples 1-19 and Comparative Examples 1-16
<Production method>
Ingredients (B) and (C) are blended into the aqueous solution of ingredient (A), and ingredients (D), (E) and other ingredients are blended as necessary, and heated and stirred at 70 ° C. for 2 hours. Thus, body cleansing materials described in Tables 1 and 2 were prepared.

<Evaluation method>
(Foam viscosity)
It diluted with 10 mL of 4 degree DH hard water with respect to 1 mL of manufactured body washing | cleaning materials, and was bubbled by hand washing for 20 seconds. This foam was put into a 50 mL beaker, and the foam viscosity (mPa · s) at 25 ° C. after 30 seconds was measured using a B-type viscometer (Tokyo Keiki Co., Ltd.). The rotation speed at this time is 12 rpm, and the rotor is No. 3 was used.

(Foam sensory evaluation)
1 mL of the body washing material thus prepared was diluted with 10 mL of 4 ° DH hard water and subjected to sensory evaluation by foaming by hand washing for 20 seconds. Sensory evaluation was conducted by 10 expert panelists, and 9 out of 10 foams were creamy based on soap (15% aqueous solution consisting of lauric acid / myristic acid / palmitic acid = 6 / 4.5 / 4.5). When it is determined that the soapy creamy foam quality is “A”, “B” when 10 to 10 out of 10 are judged as soapy creamy foam quality, 10 “C” when 5-6 of them judge soapy creamy foam, “D” when 3-4 of 10 judges soapy creamy foam “E” when 2 or less of 10 people judged soapy creamy foam quality.

(Evaluation of foaming amount)
1 mL of the manufactured body washing material was diluted with 10 mL of 4 ° DH hard water and foamed by hand washing for 20 seconds to evaluate the amount of foaming. The foaming amount was evaluated by 10 expert panelists. About the amount of foaming based on soap (15% aqueous solution consisting of lauric acid / myristic acid / palmitic acid = 6 / 4.5 / 4.5) When 9 or more people judge that the amount of foaming is greater than soap, “A”. When 7 to 8 of 10 people judge that the amount of foaming is greater than soap, “B”. “C” when a person judges that the amount of foam is greater than soap, “D” when 3 to 4 of 10 people judge that the amount of foam is greater than soap, “D”; When it was determined that the amount of foaming was equal to or greater than “E”.

[Storage stability (1)]
40 mL of the manufactured body washing material was placed in a 50 mL glass container (inner diameter 3.2 cm) and stored at room temperature (25 ° C.) for 6 months to confirm the presence or absence of separation.
[Storage stability (2)]
The produced body wash 40 mL was put in a 50 mL glass container (inner diameter 3.2 cm) and subjected to a 14-day cycle test at −28 to 40 ° C. (one reciprocation / 8 hours) to confirm the presence or absence of separation.

  From the results of Table 1, the body cleanser of the present invention containing the component (B) shows a high foam viscosity regardless of which component (C) is used (Examples 1 to 3), and in addition to the component (E). It can be seen that even when the nonionic surfactant (Examples 4 and 6) or the amphoteric surfactant (Example 5) is added, a creamy foam is formed. However, in Comparative Example 2 in which the carbon number of the component (B) is extremely short, Comparative Example 3 in which the carbon number is extremely long, and Comparative Examples 1 and 4 to 10 that do not include the component (B), the foam viscosity is about 500 mPa · s. Yes, foam quality was not improved.

  From the results of Table 2, the body cleansing agent of the present invention containing components (A), (B), and (C) is sufficient for components (A), (B), and (C) that have a prescription other than a specific ratio. There is no effect. In Comparative Examples 11 to 13, since the component (B) is excessive, the foaming property is remarkably lowered, and the foamy creamy is also insufficient. Moreover, in Comparative Examples 14-16, it turns out that a creamy foam is not obtained because of a component (B) shortage.
