[0001]

FIELD OF THE INVENTION The present invention is a detergent composition having low irritation, excellent foaming properties, excellent feeling after washing, a viscosity useful as a detergent composition, and good stability over time. Regarding

[0002]

2. Description of the Related Art In recent years, as a factor required for a detergent composition, not only a good feeling in use but also safety in use, that is, so-called hypoallergenicity can be mentioned. Attempts have been made to use a mild surfactant as such a detergent composition, and as such a surfactant, an acylalkyl taurate anionic surfactant or an acyl isethionate anionic surfactant is used. Examples thereof include ionic surfactants, amide ether sulfate type anionic surfactants and alkylimino dicarboxylate type amphoteric surfactants.

As a composition using an acylalkyl taurate type anionic surfactant, a composition obtained by combining an aminoacetic acid betaine type amphoteric surfactant and an alkanolamide (Japanese Patent Publication No. 59-42038), amine Composition combining oxide and alkanolamide (Japanese Patent Publication No.
-26673) and the like, as a composition using an acyl isethionate-type anionic surfactant, a composition in which a betaine-type amphoteric surfactant is combined (JP-A-60-161498), HLB A composition in which a nonionic surfactant of 10 to 16 is combined (JP-A-61-272297) is an acylglutamate-type composition as a composition using an amide ether sulfate-type anionic surfactant. A composition in which an anionic surfactant is combined (JP-A-2-235999), a composition in which an acyl-β-alaninate type anionic surfactant is combined (JP-A-2-222439), and the like, As a composition using an alkylimino dicarboxylate-type amphoteric surfactant, a composition in which an alkyl glycoside is combined (JP-A-2-84496) and an amidoamine-type amphoteric surfactant are combined. Composition (JP-A-63-
161080 publication) and the like.

Further, especially as a personal cleansing composition,
Higher fatty acid salts are useful in terms of feeling of freshness after washing and good defoaming, and a composition in which various surfactants are blended with the higher fatty acid salts to compensate for defects such as poor stability over time of the higher fatty acid salts alone. Things are being developed. Examples of such higher fatty acid salt-based compositions include compositions obtained by combining a higher fatty acid salt, a synthetic surfactant, a humectant such as glycerin and vegetable oil, and a cationic polymer compound (Japanese Patent Laid-Open No. 62-251).
99), a composition in which a sodium salt of a higher fatty acid is combined with a nonionic surfactant or an alkyl ether sulfate type anionic surfactant (JP-A-54-13512).
(Japanese Unexamined Patent Publication No. 61-287992), and a composition in which a triethanolammonium salt of a higher fatty acid and an acylglutamate type anionic surfactant are combined.

[0005]

The cleaning composition is generally filled in bottle-type or tube-type containers. Therefore, the detergent composition is required to have an appropriate viscosity so that it can be smoothly taken out from the container at the time of use and does not easily fall off from a hand, a towel, a sponge or the like. However, it was difficult to obtain an appropriate viscosity in the composition using the above mild surfactant except for some formulations. It is known to use an inorganic salt such as sodium chloride or a polymer compound in order to impart a thickening effect, but the addition of these may significantly reduce the stability over time or impair the feeling of use. There were many.

Further, in a personal cleansing composition based on a higher fatty acid salt, when a salt of a fatty acid having a short carbon number is used, good foaming property can be obtained, but this is strongly irritating to the skin. In consideration of skin irritation, when a salt of a fatty acid having a long carbon number is used, the foamability during use is significantly reduced, and the temporal stability is also reduced. In addition, a detergent composition based on a higher fatty acid salt has an excessive degreasing power, so that the skin feels tight. If the ratio of other synthetic surfactants is increased to solve these drawbacks, the feeling of refreshing after washing is impaired, and a feeling of sliminess may be felt, or foam breakage may become worse. Was there. A body cleansing composition based on a higher fatty acid salt having a suitable feel and aging stability and an appropriate viscosity has not been obtained.

The present invention provides a detergent composition having a low irritation, an excellent foaming property, a feeling of use after washing, a viscosity useful as a detergent composition, and a good stability over time. It is a thing.

[0008]

It is clear that the composition is easy to handle and has good stability over time. The composition of Comparative Example 1 has a large weight ratio of oleic acid and a small weight ratio of lauric acid of the mixed fatty acid of a), and thus has a low foaming property and poor stability over time. Since the composition of Comparative Example 2 has a large weight ratio of stearic acid as the mixed fatty acid of a), it has a low foaming property, has a tight feeling on the skin after washing, and has poor stability over time. The composition of Comparative Example 3 had H of d)
Since the LB exceeds 9, an appropriate viscosity as a cleaning composition cannot be obtained and the handleability is poor. The composition of Comparative Example 4 had a c) content of more than 10% by weight, so that it had a strong slimy feel during washing, no refreshing feel after washing, and poor stability over time. The composition of Comparative Example 5 has a low foaming property because d) exceeds 10% by weight, is difficult to come out of the container, and has poor stability over time. The composition of Comparative Example 6 had an a) / b) of more than 10/1, so that the composition had a strong irritancy, a tight feeling on the skin after washing, and poor stability over time. The composition of Comparative Example 7 has a) / b) of 1
Since it is less than / 10, a suitable viscosity as a cleaning composition,
No refreshing feeling after washing, and poor handleability and stability over time. The composition of Comparative Example 8 has a poor stability over time because it is thickened with sodium chloride without using d). Since the composition of Comparative Example 9 uses lauryldimethylaminoacetic acid betaine instead of b), it has a strong irritancy, a strong slimy feel at the time of washing, is hard to come out of the container, and has poor stability over time. Since the composition of Comparative Example 10 uses lauric acid diethanolamide instead of d), the composition has strong irritation, an appropriate viscosity as a detergent composition cannot be obtained, and handleability and stability over time are poor. Since the composition of Comparative Example 11 uses lauryldimethylaminoacetic acid betaine and lauric acid diethanolamide in place of b) and d), it has strong irritation, has a strong slimy feel at the time of washing, and is hard to come out of the container. It does not give a refreshing feeling afterwards and is poor in stability over time. The composition of Comparative Example 12 had a) + b) + c) + d) of less than 10% by weight, and thus had a low foaming property, did not have an appropriate viscosity as a detergent composition, and did not provide a refreshing feeling after washing, and was easy to handle. Is bad. Comparative Example 13
The composition of (a) + a) + b) + c) + d) is more than 60% by weight, so that it is irritating, has a strong feeling of tightness on the skin after washing, is hard to come out of the container, and has poor stability over time.
