Description

DETAILED DESCRIPTION OF THE INVENTION 1. The present invention relates to a detergent composition that prevents darkening of clothes and deterioration of fragrance, and allows rinsing work to be completed in a short time.

In response to the recent drought situation, attempts have been made to develop detergents that can complete the rinsing process in a short time, and many of these detergents contain silicone, soap, or cationic surfactants. However, when washing clothes with such detergents, it causes a decrease in detergency, a significant drop in foaming during washing, and adhesion of particulate matter to the washed fabric, which is harmful to consumers. did not give favorable results.

In particular, when washing clothes with a detergent containing a cationic surfactant, the rinsing time is shortened, but the clothes tend to darken as the washing process is repeated. This is because the cationic surfactant and the anionic surfactant, which is the main active ingredient of the detergent, form a complex, and dirt components are adsorbed to this complex and accumulated on the fibers.

Conventionally, as a method for preventing recontamination in detergents in which a cationic surfactant is added at the same time as washing, it has been proposed to add a water-soluble polymer (Japanese Patent Application Laid-open No. 59-6299). However, it is necessary to mix the cationic surfactant and the water-soluble polymer as uniformly as possible, and further improvements have not been made in practical terms due to problems such as an increase in the number of manufacturing steps.

In addition, in recent years, it has been proposed to use the same cellulase as the present invention in detergent compositions to impart flexibility (Japanese Unexamined Patent Publication No. 57-23699); That's what I mean.

This is essentially different from the cleaning composition of the present invention, which contains a cationic surfactant to shorten the rinsing time.

In addition, detergent compositions containing sulfites are
This method was proposed in Japanese Patent No. 07 and is well known. However, this document only discloses that the detergent contains 10 to 84% by weight of sulfite to produce a low-phosphorus to high-phosphorus detergent. In addition, zeolite-enzyme-containing detergents have been proposed, but their main purpose is to improve detergency.

Thus, there is no suggestion of incorporating cellulases or sulfites into detergent systems to which cationic surfactants have been added in order to shorten the rinsing time.

An object of the present invention is to provide a detergent composition that can complete the rinsing work in a short time without causing darkening of clothes or deterioration of fragrance.

The cleaning composition of the present invention is characterized by containing the following components (A), (B), and (C).

(A) Cationic surfactant represented by general formula (1): 0.5 to 7% by weight.

In the formula, each symbol represents the following.

Fungal cellulases produced from ermoidea):
O,OS~5% by weight.

(C) Sulfite: 0.2 to 2% by weight.

The present invention will be explained in more detail below.

Specific examples of the cationic surfactant as component (A) include distearyldimethylammonium salt, dihydrogenated beef tallow alkyldimethylammonium salt, distearylmethylhydroxypupylammonium salt, and distearyldihydroxyethylammonium salt. Further, specific examples of halogen as a counter ion include chloride and bromide.

(A) Component cationic surfactant is present in the detergent composition.
．． It is blended in an amount of 5 to 7% by weight, preferably 1 to 5% by weight.

If the amount is less than 0.5% by weight, the rinseability will not be improved, and if it exceeds 7% by weight, foaming during washing will be significantly reduced, which is not preferable.

(A) The cationic surfactant is desirably blended into the granular detergent composition in the form of granules having a particle size of about 50 to 1000 μm by crushing, granulation, spraying, or the like.

The cellulase component (B) is an enzyme that is active at a pH of 7 to 10 and at a temperature of 70°C or lower, preferably 60°C or lower. As already explained, the use of this enzyme as a roughness reducing agent (softening agent) is described in detail in JP-A-57-23699. This fungal cellulase is 5P-22 from Novo Industries.
Component (C) cellulase, which is available under the name No. 7, can be used in detergent compositions containing
It is blended in an amount of 5.0% by weight, preferably 0.5 to 3.0% by weight. If the amount is less than 0.05% by weight, darkening cannot be sufficiently prevented, and if it exceeds 5.0% by weight, the effect will be saturated, which is economically disadvantageous.

If there is a lot of dust in cellulase, various problems will occur during the process of mixing cellulase and detergent components and when using cellulase-containing detergents, so it is desirable to have less dust.
It may be made into encapsulated granules as described in Publication No. 5.

Or Marumerizer (Marumerizer,

o 3/1970. It is preferable to use the granulator described in p. 147-153. Additionally, the cellulase may be coated with a whitening agent, preferably TiO, in combination with a dust binder and mixed with the granular cleaning agent.

Specific examples of the sulfite of component (C) include Na, SO,
, K, SO3, KHSO3, Mg5O.

Among them, N a x S Oz (
Sodium sulfite is preferred.

Component (C) is blended in the cleaning composition in an amount of 0.2 to 2% by weight. If the amount is less than 0.2% by weight, darkening cannot be sufficiently prevented, and if it exceeds 2% by weight, the odor will deteriorate.

A perfume can be added to the cleaning composition of the present invention to impart a fragrance, and deterioration of this odor can also be effectively prevented by using the above three components in combination.

Although not particularly limited, examples of fragrances include allylisoamyloxyacetate, cyclamenaldehyde, tonalid, p-tart-butyl-dihydrocinnamaldehyde, tetrahydrolinalool, 6-acetyl-1-isopropyl-1,2,3,5-tetrahydroindan , methyl-β-naphthyl ketone, acetophenone, nerol,

Methyl cinnamate, rosephenone, phenylethyl acetate, benzyl acetate, etc. can be used in combination.

Optional components such as other surfactants and builders can be added to the cleaning composition of the present invention. Specific examples of these include the following.

(1) Anionic surfactants such as linear alkylbenzene sulfonates, α-olefin sulfonates, and alkyl sulfates, amphoteric surfactants such as alkyl betaines, and nonionic surfactants such as alcohol ethoxylates.

(2) Alkali builders such as carbonates, silicates, and borates.

(3) Chelate builders such as aluminosilicates, nitrilotriacetates, and polyacrylates; (4) Oxygen bleaches such as percarbonates and perborates.

(5) Anti-recontamination agents such as polyethyl glycol, carboxymethyl cellulose, and methyl cellulose.

(6) Foam control agents such as soap.

(7) Extending agents such as optical brighteners, dyes, and Glauber's salt.

According to the present invention, by using the three components of a cationic surfactant, a specific cellulase, and a sulfite salt, they work together to prevent darkening of clothes even after repeated washing. And again.

It is possible to realize a cleaning composition that does not lose its fragrance over time and can complete rinsing work in a short time.

Hereinafter, the effects of the present invention will be specifically explained using examples. The performance evaluation method in Examples is as follows.

Add 30 times the ratio, wash for 10 minutes, then dehydrate for 1 minute. The operation of rinsing the cloth to be washed with 30 fi of 4"DH water for 3 minutes was repeated twice, and the rinsing liquid obtained in the final operation was evaluated for the remaining foam according to the following criteria.
