Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides a low-irritant detergent composition, and more particularly, a detergent composition with low irritation to the skin and eyes, excellent detergency and foaming. The present invention relates to a cleaning composition having a powerful cleaning agent composition.

[Conventional technology and its problems]

Detergents are naturally required to have excellent cleaning properties such as detergency and foaming power, as well as cleaning agents for the human body (shampoo, body shampoo, etc.), cleaning agents for tableware and cooking utensils, and wool. Light detergents and other detergents that come into direct contact with the skin are required to have low irritation to the skin and eyes, and also to have good solution stability.

Surfactants, which are the main components of these cleaning agents, are mainly linear alkylbenzene sulfonates (LAS),
Alkyl sulfate salt (As), &lJ oxyethylene alkyl ether sulfate i (Alas)
, a-olefin sulfonate (AO8) and other anionic surfactants are used. However, although anionic surfactants have good cleaning power, they are all irritating to the skin and eyes, and cannot be said to be the best surfactants as the main components of the cleaning agent.

By the way, as a system that satisfies these demands to some extent, what have you recently done? The combination of a lyoxyethylene alkyl ether sulfate and an imidacillin type amphoteric surfactant has become popular, particularly in shampoos. However, with this combination? If the ratio of lyoxyalkyl ether sulfate is high, the shampoo properties such as foaming properties and detergency will be satisfied, but the irritation will be relatively high. Although the irritation level is lowered, there is a drawback that the foaming property and cleaning power are insufficient.

In order to solve the above problems, Japanese Patent Application Laid-Open No. 62-12739
No. 6 contains a sulfosuccinic acid surfactant as the third essential component. however,
The sulfosuccinic acid surfactant itself is a relatively mild anionic surfactant, and is also disclosed in JP-A-56-38395.
As shown in No. 1, it has the effect of reducing the irritation of AES when combined with Alas, but because it generally lacks foaming power and low-temperature stability, it is used only as a co-activator for AES. It has a desk shape.

On the other hand, in recent years, attention has been called to the by-product of dioxane in AES, especially in Toyutsu and Q, and the trend has been to remove dioxane from S, which is a hypoallergenic cleaning product that does not contain AES. The development of new agents is desired.

A comparatively similar cleaning agent that does not contain any AES is JP-A-55-86892.
There is a product containing two components, a sulfosuccinic acid surfactant and an imidacillin amphoteric surfactant, but this also has problems with foaming properties.

[Means for solving problems]

As a result of intensive studies to solve this problem, the inventors found that (A) α-olefin sulfonate % (B)! By adding C) an imidacillin amphoteric surfactant and an alkanolamide type nonionic surfactant to a given sulfoconolic acid ester surfactant, irritation is reduced without impairing foaming power and detergency. Moreover, the present inventors have discovered that a cleaning composition that can satisfy the stability of the solution can be obtained, and have completed the present invention.

That is, the present invention provides (A) an α-olefin sulfonate, (B) the following formula [I] R-C-CM-CM2COOM (I) SO

(The weight ratio of Di/(A) + (B) is 1/20 to 1/2 zb, and the total weight of (A) + (B) 1010 is 10 to 40% by weight. The object of the present invention is to provide a world-irritating cleaning composition characterized by containing:

As the α-olefin sulfonate (A) used in the present invention, for example, the following formula (V) R1(lSO3M" [v] represents an alkyl group substituted with an alkenyl group or a hydroxyl group, and M" represents a water-soluble salt-forming cation selected from the group consisting of hydrogen or an alkali metal. It will be done.

The average carbon number of RIO is preferably 14 to 16 from the viewpoint of foamability and stability of the composition.

As the sulfosuccinic ester surfactant (B) in the present invention, one derived from a higher alcohol ethoxylate or higher fatty acid amide represented by the above formula (1) and having an ethoxy group is used. The polymerization number m of ethoxy groups in formula (1) is more preferably from 2 to 10, since although the irritation level decreases as the number m increases, the basic performance as a cleaning agent decreases. In addition, as the higher alcohol represented by RIOf(), not only primary alcohols but also secondary alcohols are preferably used.

Examples of the imidacillin-based amphoteric surfactant in the present invention include the following compounds '111 (amidoamine type amphoteric surfactant) and the like.

In the present invention, the weight ratio of (A)/(B) is 1/3 to 3

Although the foaming power is sufficient, a hypoallergenic composition cannot be obtained.
On the other hand, if it exceeds 1/1, it is not preferable because the foaming power and stability will be impaired.

Further, the weight ratio of 0/capital + (B) is used in a range of 1/20 to 1/2. If it exceeds 1/2, it becomes difficult to remove the foam, and if it becomes less than 1/20, the foaming of the cleaning agent decreases.
This is not preferable because the condition of the bubbles also deteriorates.

[Action and effect of the invention]

According to the present invention, a detergent that is hypoallergenic and has excellent detergency can be obtained. Therefore, the composition of the present invention can be used, for example, as a hair and skin cleansing agent for infants, a kitchen detergent for housewives who tend to get rough hands, a daily shampoo for people who wash their hair every day, and even for long-term contact with shampoos for professional purposes. It is suitable as a hypoallergenic shampoo for hairdressing for people who have no choice but to use it.
