Description

The washing composition that comprises the gentle release peroxyacid bleach source of tensio-active agent

The present invention relates to contain the detergent composition of tensio-active agent and peroxyacid bleach source, the mode that discharges in washing soln with respect to described peroxyacid bleach of the hang-over n. of described tensio-active agent wherein is provided.

For prescription Shi Eryan for the detergent composition that in washing methods, uses as laundry or machine wash up method, can be satisfactorily get on except that unctuousness from the basic thing of pollution/contamination, coloured dirt/spot such as food, makeup, leather polish and human body dirt are special difficult tasks.

Traditionally, this class dirt/spot can be removed by using surface active agent composition and bleaching components, and SYNTHETIC OPTICAL WHITNER such as oxygen bleaching agent comprise hydrogen peroxide and organic peroxide acid.Organic peroxide acid makes by the reaction of the peroxidation hydrogenolysis on the spot between hydrogen peroxide and the organic peroxide acid bleach precursor (perhydrolysis reaction) usually.

For some organic peroxide acid SYNTHETIC OPTICAL WHITNER of using in clothes washing method, the problem that is faced then is that these organic peroxide acid SYNTHETIC OPTICAL WHITNER exist influence to be washed the possibility of fabric color stability.The influence of fabric color stability is comprised fading of coloured dye on the regional area of fabric or " irregular (patchy) " bleaching.

Therefore, the detergent formulation teacher is faced with preparation not only will bleach removal dirt/spot most possibly, and will make the existence of any unwelcome fabric color stability action of SYNTHETIC OPTICAL WHITNER reduce to minimum double challenge.

The applicant finds, the any unwelcome fabric color stability action that uses the organic peroxide acid SYNTHETIC OPTICAL WHITNER to be produced in the washing methods is not only relevant with the character of organic peroxide acid, but also the peroxy acid abswolute level that exists in speed that discharges in washing soln with peroxyacid bleach and the washing soln is relevant.

The same with the high SYNTHETIC OPTICAL WHITNER abswolute level in the washing soln, the fast velocity that peroxyacid bleach discharges in washing soln often also causes the possibility of the unwelcome fabric color stability action that can be observed to increase.

Although by reducing the rate of release of SYNTHETIC OPTICAL WHITNER used in the washing process, or the abswolute level that reduces SYNTHETIC OPTICAL WHITNER can improve this problem, all exists the negative interaction to dirt/spot bleaching removal ability simultaneously.

Yet, the applicant has now found that, use comprises the composition (release with respect to tensio-active agent wherein is provided, postpones the mode that peroxyacid bleach discharges in washing soln) of tensio-active agent and peroxyacid bleach source, the bleaching detergent dirt/spot ability that can be enhanced.

In addition, when described composition used in clothes washing method, the fabric color stability problem also was reduced.

The applicant also finds in addition, comprises in use before the washing methods washing of SYNTHETIC OPTICAL WHITNER of washing composition product, pollutes basic thing earlier with the solution pre-treatment that contains tensio-active agent, can better be bleached removal dirt/spot effect.

Therefore, one aspect of the present invention provide be adapted at doing washing and machine-washing tableware method in use and have a composition that strengthens the bleaching detergent ability.

Another aspect of the present invention provides the composition that is adapted at using in the clothes washing method, and wherein said composition exhibiting goes out the tendency of less generation negativity fabric color stability action.

Related fields more of the present invention provide dirt/spot pretreatment process, and this method is included in before the washing composition product washing that contains SYNTHETIC OPTICAL WHITNER, pollutes basic thing with the solution pre-treatment that contains tensio-active agent earlier.Summary of the invention
