Description

Oxygen-based bleach composition {BLEACHING AGENT COMPOSITION}

The present invention relates to an oxygen-based bleach composition, and more particularly, it is excellent in preventing decontamination to direct and reactive dyes at low or high temperatures, as well as in preventing refouling, and effectively removing hydrophilic and hydrophobic stains. The present invention relates to an oxygen-based bleach composition having excellent anti-disinfection effect by solving a problem of desalination due to desalination, which is a disadvantage of bleach.

For bleaching, our country has used the washing method of boiling, sunlight (ultraviolet), and drying for decades. The method as described above can not only increase the cleaning power, but also promote the oxidation to increase the bleaching performance, and has the effect of enabling sterilization. However, this method is inconvenient that the person who washes the laundry, washes, spreads on the clothesline and has to dry the laundry.

On the other hand, as a washing method using bleach from Europe was used, it was possible to more easily remove bleachable contamination such as fruit juice, coffee, wine, grass water (juice). Since the general bleaching process involves several chemical mechanisms at the same time, there is always a possibility of dye transfer for dyed clothes.

Conventionally, carboxymethyl cellulose (CMC) and polyvinylpyrrolidone (PVP) are mainly used to impart re-fouling prevention function and anti-drinking function to general detergents. In particular, polyvinylpyrrolidone is known to have a good effect at a high temperature rather than a low temperature as a material imparting a dye preventing function widely used worldwide. Their anti-degradation mechanism functions to prevent dye transfer by increasing the affinity with the dye by the polymer to separate the dye from the fiber because the dye is wrapped by the polymer rather than being dyed to other fibers.

In early years, laundry detergents and bleaches have been used in drum washing machines, causing serious damage to clothes and detergents.

Accordingly, it has been applied by introducing a detergent having a decontamination function, these polyvinylpyrrolidone having a decontamination function at a high temperature was mainly used due to the habit of washing at a high temperature.

On the other hand, most of domestic washing conditions are to be washed at room temperature, 20-25 degrees Celsius in the summer, even in winter, the room temperature is even 5 ℃ in cold water may be washed. In such domestic washing conditions, it is necessary to use a polymer having excellent anti-inflammation function even at a low temperature to properly perform the anti-inflammation function. In particular, in the case of the oxygen-based bleaching agent having excellent cleaning and bleaching performance, the problem about the dichloride is more serious.

In general, anti-degradation polymers are commonly used polypyrrolidone (PVP) in the form of polypyrrolidone, in addition to the pyridine N-oxide (pyridine N-oxide) of the polymer is also used. These functions not only prevent decontamination, which is one of important functions in laundry detergent, but also prevent recontamination.

The polypyrrolidone is a nonionic form having no polarity in structure, and the pyridine N-oxide has an amphoteric structure having both (+) and (-) charges at the same time, so it has better affinity for dyes than other nonionic systems. It is known.

Such pyridine N-oxides have been described in US Pat. Nos. 5,458,810, 5,460,752, and 5,804,543 for use in powder detergents as anti-degradant functions. However, the above techniques do not reveal the anti-dyeing effect of the affected anti-dyeing polymer for each of the surfactants contained in the detergent. Moreover, the bleaching agent containing balanced bleaching power and anti-dyeing function by applying to an oxygen-based bleaching agent is still It is not realized.

Therefore, there is a need for further research on an anti-dye bleach having excellent anti-dyeing effect and at the same time excellent in bleaching power.

In order to solve the problems of the prior art as described above, an object of the present invention is to provide an oxygen-based bleach composition excellent in anti-degreasing effect to the direct and reactive dyes, and excellent in preventing re-fouling adhesion even at low or high temperatures.
