Detergent composition

RELATED APPLICATION

This application claims the priority of Japanese Patent application No. 10-285269 filed on Oct. 7, 1998, No. 10-285270 filed on Oct. 7, 1998, and No. 10-285271 filed on Oct. 7, 1998, which are incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates in general to a detergent composition, and more particularly to a detergent composition which foams well and does not leave a slimy feeling after use.

2. The Prior Art

Conventionally, alkyl sulfates have been used as detergents in products such as cleansing foam, body shampoo and shampoo because of their foaming quality and usability. Particularly, since hair washed with alkyl sulfates do not have a squeaky feeling, they have been used as the base agents of shampoos for a long time. They are also used in cleansing foam and body shampoo, not as the main base agent but as an assistant agent to increase foaming because they cause a slimy feeling during use. The range of applications for alkyl sulfates will extend even more if a refreshing feeling can be added to it.

BRIEF SUMMARY OF THE INVENTION

As described above, since alkyl sulfates have the superior characteristic of good foaming, if a refreshing feeling is added to them, they can be used as the main base agent for detergents other than shampoos to obtain detergents with good foaming.

The object of the present invention is to provide a detergent composition which has good foaming and does not leave a slimy feeling after use.

The blend ratio of the compounds blended, as an essential ingredient, into the detergent composition of the present invention represented by the above general formulas 1-, 2-, and 3-(1)-(10) is preferably 0.5-90 wt %. A more preferable blend ratio range is 5-40 wt %; by using a detergent composition prepared within this range, the effect of the present invention can be more clearly obtained. If the blend ratio is 0.5 wt % or less, then the effect of the present invention is hard to obtain. It is not preferable to have a blend ratio of more than 90 wt %, because then problems arise such as a reduction of the solubility in water.

Preparation methods of the compounds blended, for an essential ingredient, into the detergent composition of the present invention represented by the above general formulas 1-(1)-(10) include a method in which N-acylmethyltaurine, N-acyltaurine, alkylsulfuric ester, alkyl ether sulfuric ester, or alkylsulfonic acid is dissolved at a temperature of approximately 80° C. and an aqueous solution of the alkali metal N-methyltaurate salt or the organic alkali N-methyltaurate salt is added to it while being stirred, or an aqueous solution of the N-methyltaurine and an aqueous solution of the other alkali are separately added to it while being stirred.

Preparation methods of the compounds blended, for an essential ingredient, into the detergent composition of the present invention represented by the above general formulas 2-(1)-(10) include a method in which N-acylmethyltaurine, N-acyltaurine, alkylsulfuric ester, alkyl ether sulfuric ester, or alkylsulfonic acid is dissolved at a temperature of approximately 80° C. and an aqueous solution of the alkali metal hypotaurate salt or the organic alkali hypotaurate salt is added to it while being stirred, or an aqueous solution of the hypotaurine and an aqueous solution of the other alkali are separately added to it while being stirred.

Preparation methods of the compounds blended, for an essential ingredient, into the detergent composition of the present invention represented by the above general formulas 3-(1)-(10) include a method in which N-acylmethyltaurine, N-acyltaurine, alkylsulfuric ester, alkyl ether sulfuric ester, or alkylsulfonic acid is dissolved at a temperature of approximately 80° C. and an aqueous solution of the alkali metal taurate salt or the organic alkali taurate salt is added to it while being stirred, or an aqueous solution of the taurine and an aqueous solution of the other alkali are separately added to it while being stirred.

The detergent composition of the present invention refers to a composition which has a cleaning effect on objects. The range of objects to be cleaned is not limited. Preferably, it refers to a detergent used on human bodies, such as cosmetics and quasi-drugs. In addition to the aforementioned essential ingredients, other ingredients which are usually contained in a detergent composition can also be blended in, including anionic surfactants such as soap, a alkylsulfuric ester (salt), polyoxyethylenealkyl ether sulfuric acid (salt) and hydroxyalkyl ether carboxylic acid (salt), ampholytic surfactants such as imidazoline type ampholytic surfactants and betaine type ampholytic surfactants, non-ionic surfactants such as a polyoxyethylene alkyl ether, polyoxyethylene fatty acid ester, sucrose fatty acid ester, alkylglycoside and maltitolhydroxy aliphatic ether, cationic surfactants such as trimethylalkyl ammonium chloride, humectants such as glycerine, 1,3-butylene glycol and dipropylene glycol, extracts of plants such as Swertia japonica, Paeonia lactiflora, Iris florentina and Horsetail (Equisetum), drugs such as tranexamic acid and arbutin, perfumes and preservatives.

EXAMPLES

The present invention is further described in detail below. The present invention is not limited to these examples.

(Testing)

The compounds represented by the aforementioned general formulas 1-, 2-, and 3-(1)-(10) were subjected to a foaming test and an actual use test.

1. Foaming Test with the Shaking Method

0.5 wt % of each sample in Table 1 was dissolved in ion exchanged water with 70 ppm calcium chloride already dissolved in it. The pH was then adjusted to 7.0 with hydrochloric acid. This solution was kept at 30° C. and 20 ml of it was put into a Nessler's tube with an inner diameter of 3 cm and a height of 20 cm equipped with a sliding plug, and then tilted 90 degrees every second using a pendulum shaker. After one minute, the sample was taken out of the shaker and the foam height was measured. The time required for the foam height to be reduced to half of the original height (duration) was also measured.

(Sensory Test of Actual Use)

Fifty panelists were used to conduct the actual use test. 10 ml of a 10% aqueous solution of each sample was put on a hand and the hand was washed for 30 seconds. The feeling during use and after rinsing was rated with a five point scale based on the criteria shown in Table 1. The average of the fifty panelists was calculated to obtain the total evalution.
