Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] Technical Field The present invention relates particularly suitable bleaching composition prior to treatment of the fabric.

[0002] Peroxide bleach-containing compositions based on background hydrogen peroxide invention, laundry detergents, are described in detail in laundry products as laundry additives or laundry pretreatment agents.

[0003] It is well known to use liquid aqueous bleaching compositions containing hydrogen peroxide in the pretreatment stage of laundry. Although these liquid aqueous bleaching compositions have some bleaching ability when used in the pretreatment of soiled fabrics, there is room for improvement in the ability to remove stains, for example, various stains including fatty stains. In addition, pre-processing conditions, that is,
If the liquid aqueous composition is applied neat to the fabric and bleached followed by rinsing with water or washing and rinsing with water, there is room for improvement in bleaching capacity.

[0004] Liquid aqueous compositions of this type used in the pretreatment of laundry need to behave like water (low viscosity) for proper use. It has been found that the stain removal ability of a liquid aqueous peroxide bleach-containing composition can be improved by adding a surfactant. However, when a surfactant is added to the liquid aqueous peroxide bleach-containing composition, it can be used to effectively remove stains of the pretreated fabric, but this type of composition has a problem of high viscosity. is there.

[0005] Accordingly, formulators of bleaching compositions suitable for such pre-laundering treatments have faced the challenge of formulating a liquid aqueous bleaching composition that has excellent stain removal and bleaching capabilities while at the same time having low viscosity. encounter. Accordingly, it is an object of the present invention to provide a liquid aqueous composition which has an effective stain removal and bleaching ability under the pretreatment conditions of washing and has the property of low viscosity.

Salts, solvents, ie, viscosities selected from the group consisting of glycols as defined herein, C3-C8 alcohols, and / or aromatic alcohols as defined herein, and mixtures thereof. It has now been found that formulating a liquid aqueous composition containing a modulator can be effectively satisfied.

[0007] When such compositions are used in the pretreatment of textiles, only one of these surfactants (ie ethoxylated nonionic surfactant or bicarbonate) is used at a concentration equal to the total surfactant concentration. Various types of stain removal, including fatty stains and / or enzyme stains, while having a low viscosity, compared to the stain removal and bleaching ability obtained with the same composition containing (ionic ionic betaine surfactant). It was found to increase capacity, and more surprisingly, to increase bleaching capacity. In fact, the addition of this type of viscosity modifier adds a liquid aqueous peroxide containing an ethoxylated nonionic surfactant and a zwitterionic betaine surfactant without reducing the stain removal and bleaching ability of the composition. It has been found that the viscosity of the bleach-containing composition can be reduced. In other words, the combination of these components makes it possible for a liquid aqueous composition particularly suitable for the pretreatment of textiles to have the best stain removal and bleaching capacity and the highest viscosity properties.

Conveniently, the compositions of the present invention can be used for kitchen soils containing mainly edible oils, bathroom soils containing mainly sebum and / or soap scum, and floor soils mainly containing fine particulate soils. And more commonly fatty stains (eg, makeup of olive oil, mayonnaise, vegetable oils, lipsticks, etc.), enzyme stains (grass, blood) and bleachable stains (eg, tea, coffee) Shows effective stain removal ability. Advantageously, they also show satisfactory results on fabric and color safety when used as laundry pretreatment agents.

These compositions are also transparent over a wide range of temperatures, for example, up to 45 ° C.

[0011] It is a further object of the present invention to provide an improved liquid bleaching composition that is clear and low viscosity at a wide range of temperatures, for example, up to 45 ° C. An advantage of the composition of the present invention is that the range of soils that can be cleaned is very wide. Although the compositions of the present invention are formulated primarily for use as stock solutions in undiluted form, these compositions may be used in other laundry products such as laundry detergents and laundry additives, or in hard laundry products. It can also be used for other household uses such as cleaning surfaces. Therefore, the composition of the present invention can be used under various conditions such as hard water or soft water, or a diluted state.

It has been surprisingly found that pretreatment of the fabric with a peroxide bleach-containing composition comprising a zwitterionic betaine surfactant results in improved fabric and / or color safety. Thus, in its broadest aspect, the present invention relates to a process for pre-treating a fabric (by applying the composition neat to the fabric and rinsing them or washing them and then rinsing them with water). To bleach)
It involves the use of a composition comprising a salt-free zwitterionic betaine surfactant and a peroxide bleach. This improves color (ie, less color damage and bleaching) and / or fabric safety.

The betaine zwitterionic surfactants of this specification have the ability to further enhance the stain removal performance for fatty stains obtained with the ethoxylated nonionic surfactants of this specification, and The bleaching performance of the liquid peroxide bleach containing compositions of the invention containing these surfactants is improved. In fact, for both hydrophilic and hydrophobic fabrics, in order to obtain the best stain removal performance for various stains from hydrophobic to hydrophilic, from fine to non-fine in household goods and especially laundry products, Significant synergy was noted between these components.

The present invention uses a zwitterionic betaine surfactant in an appropriate ratio in addition to an ethoxylated nonionic surfactant in a liquid aqueous composition containing a peroxide bleach (pH less than 7). Then, for the same total concentration of surfactant, the same composition using only one of these surfactants (ie, ethoxylated nonionic surfactant or zwitterionic betaine surfactant) The ability to remove and stain various types of stains, including fatty stains (eg, lipstick, olive oil, mayonnaise, vegetable oils, sebum, makeup), compared to the bleaching and stain removal capabilities provided by the composition of It is based on what you find to do. For example, a similar fatty soil removal effect is observed due to the nonionic surfactant compared to the total concentration of ethoxylated nonionic surfactant and zwitterionic betaine surfactant present in the composition of the present invention. Only if the concentration of surfactant is very high.

The stain removal ability can be evaluated for various types of stains by the following test methods. A suitable test method for assessing the stain removal capacity of a soiled fabric under pre-treatment conditions is as follows: the composition of the present invention is applied neat to the fabric, preferably to the soiled portion of the fabric. The fabric is then left to act for 1 to 10 minutes, and the pretreated fabric is then washed under normal washing conditions, i.e., at 30 to 70C for 10 to 100 minutes. Then, with a reference composition having the same composition as the fabric pretreated with the composition of the present invention, but containing only the alkoxylated nonionic surfactant as the surfactant, or only the zwitterionic betaine surfactant. The stain removal effect is evaluated by comparing the pretreated fabric with a paired comparison. Use a visual rating from 0 to 4 to determine the difference in panel units (psu). The bleaching ability is evaluated in the same manner as the stain removal ability, but the stain used is a stain that can be bleached such as coffee and tea.

For example, the transparency of the composition can be determined by measuring the absorbance at a wavelength of 800 nm using a spectrophotometer.

The viscosity modifier of this specification can adjust the viscosity of the composition of this specification to a required range. While not being bound by theory, the ammonium salts herein have an impact on the electrostatic interaction linking the charged nonionic and zwitterionic micelles and reduce the viscosity of these compositions. It is considered. In fact, the non-ionic surfactants of the compositions of this specification are associated with zwitterionic betaine surfactants to form charged micelles (whereby the aqueous phase of the compositions of this specification Lowers the surface interface of surfactants)
. The charged micelles thus formed work together to form an elongated structure, ie, micelles bound by electrostatic interaction, which increase the viscosity. When glycols, alcohols, and / or aromatic alcohols are present, they compete with zwitterionic betaine surfactants for the formation of such micelles, forming an elongated structure of the resulting micelles And increase the viscosity of these compositions.

An advantage of the liquid compositions of the present invention is that they are physically and chemically stable when stored for extended periods of time. The chemical stability of the compositions herein can be assessed by measuring the concentration of available oxygen (sometimes abbreviated as AvO2) at a particular point in time after the composition is manufactured. The concentration of available oxygen can be measured by chemical titration methods well known in the art, such as iodine titration, thiosulfate titration, permanganate titration, and cerium titration.

[0083] In the method the present invention to preprocess the fabric, the liquid aqueous compositions of the present invention, soiled least partially undiluted to the coating of the fabric, or rinsing the fabric, or washed then rinsed before, Usually, the fabric is allowed to act for a few seconds to a few hours.

In this manner, if the composition remains on the fabric and does not dry, rinse or wash and then rinse and then 10 seconds to 1 hour, preferably 1 to 15 minutes, more preferably The composition can be allowed to act on the fabric as it is for 1 to 5 minutes. For particularly troublesome stains, it is advisable to rub the fabrics with a sponge or brush or rub each other between fabrics.

As used herein, “washing” refers to contacting a fabric in a water bath with a conventional cleaning composition comprising at least one surfactant. Washing may be performed by a washing machine or manually.

“Undiluted” means that the liquid composition is applied directly to the pretreated fabric without dilution. That is, the liquid composition of this specification is applied to the fabric as described in this specification.

According to the method of pretreating a soiled fabric of the present invention, it is desirable that the liquid aqueous composition of this specification not be left on the dried fabric. It has been found that as the water evaporates, the concentration of free radicals on the fabric surface increases, thus increasing the speed of the chain reaction. It is also believed that if the liquid composition is left on the fabric after drying, an autoxidation reaction will occur when the water evaporates. This autoxidation reaction produces peroxy radicals, which break down the cellulose. Therefore, to reduce the drop in tensile strength and color damage when pre-treating the fabric with the liquid peroxide bleach-containing composition, as described in this specification, the pre-treatment of the soiled fabric It is necessary not to leave the liquid composition on the fabric dried in the process.

The compositions of this specification can also be used in a “soaking mode”. That is, in this manner, the composition as defined herein is first diluted in an aqueous bath and formed by immersing the fabric in this bath or dissolving or dispersing a typical laundry detergent before rinsing the fabric. In addition to the cleaning solution thus obtained, the composition is immersed in a “through-cleaning” cleaning solution to which the composition defined in this specification is added. In both cases, it is essential that the fabric in contact with the composition be rinsed before the composition has completely dried. The compositions of this specification can be filled into various containers, including ordinary bottles, bottles with rollers in their openings, sponges, brushers, and sprayers, depending on the end use.
