Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has good lathering, smooth and creamy lathering properties, and, for example, smoothes the hair during hair washing and prevents tangling, as well as maintains an appropriate viscosity. and a liquid cleaning composition having excellent usability.

In recent years, growth has been on the rise.
Liquid detergent compositions such as shampoo compositions are required to have mild, creamy, and smooth foaming properties, and for this reason, amphoteric surfactants are used. Among these amphoteric surfactants, especially amidobetaine type amphoteric surfactants are less irritating to the skin, have good foaming properties, are biodegradable active agents, and have high conditioning effects on the skin and hair. Therefore, it is frequently used in shampoo compositions.

However, amidobetaine-type amphoteric surfactants are more expensive than anionic surfactants, so they are used in combination with anionic surfactants for economical reasons.
;However, when an amidobetaine type amphoteric surfactant and an anionic surfactant are combined, a gel is formed and the viscosity of the shampoo composition becomes extremely high. There are many problems in terms of usability, such as making it difficult to remove the product from the container or applying it to the hair.

In addition, in order to solve these problems, measures have been taken such as adding lower alcohols such as ethanol to the shampoo composition to lower the viscosity of the composition, but in this case, the foaming of the composition may decrease or However, it has the disadvantage of poor storage stability.

Therefore, it has been desired to develop a liquid detergent composition that has good foaming performance and good usability.

The present invention was created in view of the above circumstances, and has good foaming, smooth and creamy foam performance, and when used in a shampoo composition, for example, it smoothes the hair during washing, prevents tangling, and provides a suitable amount of foam. It is an object of the present invention to provide a liquid cleaning composition that has viscosity and is excellent in usability.

In order to achieve the above object, the inventors of the present invention have made extensive studies and found that a liquid detergent composition containing an anionic surfactant and an amidobetaine type amphoteric surfactant has a carbon atom number of 4.
An anionic surfactant when one or more compounds selected from ~12 branched diols and mono- and diols with 4 to 12 carbon atoms having one or more ether bonds in the molecule are blended. Since the gel formed by the combination of 25 and an amidobetaine type amphoteric surfactant is destroyed by the above mono- or diol, the viscosity of the composition can be easily reduced.
The viscosity can be adjusted to an appropriate viscosity of 5000 centipoise or less at ℃, therefore, it has good foaming, smooth and creamy foam performance, and when used in a shampoo composition, for example, it can smooth and detangle the hair during hair washing. The present inventors have discovered that a liquid cleansing composition can be obtained that prevents hair loss and is easy to spread onto the hair, is easy to take out from the container during use, and has excellent usability, and has thus arrived at the present invention.

Therefore, the present invention provides a liquid detergent composition comprising an anionic surfactant and an amidobetaine type amphoteric surfactant, a branched diol having 4 to 12 carbon atoms, and an ether bond in the molecule. 4 to 1 carbon atoms with one or more

Also, prior to each side, methods for evaluating the shampoo compositions employed on each side are shown.

〔Evaluation methods〕

(1) Shampoo performance (foaming performance) ■ Foaming A panel of 10 women and 10 men washed their hair using the shampoo composition, and evaluated the lathering quality according to the following criteria.
Sensory evaluation was performed in stages.

Evaluation criteria 0: Sufficient foam is generated and hair is easy to wash.

Δ: Slightly less foam, slightly difficult to wash hair.

×: Foaming is weak and hair washing is difficult.

■ Smoothness and tangle-free hair during washing The same panelists as above washed their hair using the shampoo composition, and evaluated the smoothness and tangle-freeness of the hair during washing according to the following criteria.
Sensory evaluation based on 6 evaluation criteria: 0: Smooth hair, no tangles.

Δ: Hair is slightly tangled.

×: The hair is not smooth and the hair is tangled.

(2) Usability ■ Ease of spreading on hair The same panelists as above washed their hair using the shampoo composition, and evaluated the ease of spreading of the shampoo composition on the hair at the time of hair washing according to the following criteria. evaluated.

Evaluation criteria 0: Easily spreads on hair.

Δ: Slightly difficult to spread on hair.

×: Difficult to spread on hair.

(2) Ease of taking out the shampoo composition A commercially available liquid shampoo bottle was filled with the shampoo composition, and the same panelists as above conducted a sensory evaluation of the ease of taking out the shampoo composition from the container on a three-point scale according to the following criteria. At the same time, the viscosity of the shampoo composition (Brook
field viscosity) was measured.

Evaluation criteria 0: Easy to take out from container, no problem.

(Viscosity 5000cp/25℃ or less) Δ: Slightly easy to take out from the container.

(Viscosity 5000-10000 cp/25°C) ×: Easy to take out from the container.

(Viscosity 10,000 cp/25°C or more) [Examples 1 to 6. Comparative Examples 1 and 2] Shampoo compositions having the compositions shown in Table 1 were prepared and evaluated using the above method.

The results are shown in Table 1.

From the results in Table 1, the shampoo composition containing only an anionic surfactant (Comparative Example 1) leaves the hair with insufficient smoothness and tangle-free properties during hair washing. When an amidobetaine-type amphoteric surfactant was used in combination (Comparative Example 2), the hair during washing was smooth and free of tangles, but the viscosity of the composition was very high, making it difficult to spread it onto the hair and remove it from the container. It was less easy.

On the other hand, a shampoo composition (Example 1 Items 6) to 6) are easy to use as they lather well, leave hair smooth and tangle-free during washing, have smooth and creamy foaming properties, and are easy to spread onto hair and take out from the container. It was excellent.

In addition, as the anionic surfactant, polyoxyethylene lauryl ether triethanolamine salt, sodium salt of N-lauryl glutamic acid, N-lauroyl sarcosine sodium, etc., the above-mentioned anionic surfactant, mono or diol, 2 ,2-dimethyl-1,3

Similar results to Examples 1 to 6 were obtained when the above-mentioned mono- or diols such as lengelicol monoethyl ether were used.

[Examples 7 and 8] Shampoo compositions having the compositions shown in Table 2 were prepared and evaluated using the above method.

The results are shown in Table 2.

Table 2 Even when each component such as sodium and citric acid was blended with the essential components, the foaming performance and usability were good.
