Description

150992

The invention relates to a multifunctional fabric or fabric softening and bleaching product which softens laundry, reduces or eliminates static adhesion of synthetic fabrics and accelerates the cleaning of laundry.

5

The use of numerous and various chemical substances and especially cationic compounds in plasticizers for textile products is well known in the art. It is also well known to utilize the softening effect of such materials during the washing operation and especially during the rinsing period of the washing process. This technique has been necessitated by the fact that the previously used plasticizers, which have mainly been cationic, are not compatible with the major detergent type used during the wash period. Anionic detergents have been used in the vast majority of cases in home washing. It has been found that even traces of anionic materials result in a precipitate which reduces the effectiveness of said cationic fabric softeners. This demonstrated incompatibility has necessitated the use of cationic quaternary plasticizers for washing during the rinse period after rinsing several times to free the washed clothing from traces of anionic detergent.

likewise, bleaching agents are usually added to the laundry as a separate step during the washing operation. Thus, it appears that so far two separate products and two separate additives have been necessary in connection with the washing operation.

It has now been found that a single multifunctional product compatible with organic detergents can advantageously be added to the laundry during the washing period, which essentially comprises a cationic plasticizer and an inorganic peroxygen bleach. The present product, which is preferably particulate, causes the laundry treated therewith to soften, to become antistatic, to be purified to an increased extent and to free from stains.

- -J

Accordingly, the object of the present invention is to provide a fabric softening and bleaching product with antistatic properties, which product is compatible with organic detergents including anionic and nonionic detergents.

The fabric softening, bleaching and antifouling product of the invention is characterized by the characterizing part of claim 1.

The invention also relates to a method for simultaneous bleaching, softening and elimination of the adhesive properties, which method is characterized by the characterizing part of claim 7.

The cationic fabric softeners useful in the product of the invention are known commercial products and comprise 40 cationic plasticizers selected from the nitrogenous plasticizers containing at least one group of 8-22 carbon atoms and at least one group of 12-22 carbon atoms.

Generally, the quaternary ammonium plasticizers have the following formulas: 10 R R3 + X- R1 (CH2CH2O) nH + ^ N X- R2 / "R3 20 Γ N - R1- / X-

R4 (CH9CH90) H

25 is a long chain aliphatic group of 8-22 carbon atoms, 2 R is a long chain aliphatic group of 8-22 carbon atoms or a lower alkyl group of 1-4 carbon atoms or an aryl or aral = 5 4-cooling group, R and R 2 are lower alkyl groups, n is a number between 1 and 15 and X is a water-soluble salt-forming anion such as a halide genide, i.e. chloride, bromide, iodide, a sulfate, acetate, hydroxide, methosulfate or the like inorganic or organically soluble mono- or dibasic group. Examples of quaternary ammonium plasticizers suitable for use in the product of the present invention include the following: hydrogenated ditalgium = dimethylammonium chloride, ethoxylated distearyl dimethylammonium chloride, 1-hydroxyethyl-1-methyl-2-heptadecylimidazolammonium ammonium chloride, dime = ,, di-coco dimethyl ammonium chloride, cetylpy = 150992 4 rhidinium chloride, higher-alkyl-dimethylbenzylammonium chloride, di-iso = butylphenoxyethoxyethyldimethylbenzylammonium chloride, laurylisoqui = nolinium bromide, distearyldimethyl-quaternary dimethylarachidyl, behenyl quaternary ammonium = chloride, di- (soy) -dimethylammonium chloride and di (coconut) dimethylammonium chloride, benzyldimethylstearylammonium chloride, etc.

When the term "coconut" is used, it includes fatty acid groups formed in coconut oil fatty acids. Such acids contain from ca. 8-18 carbon atoms per molecule predominantly in C

An essential component of the present softening product is an inorganic bleaching peroxygen compound. Any of the peroxide compounds used in the technique 15 as bleaching agents are suitable for use herein, and as typical examples which do not involve any limitation, mention should be made of inorganic persaltes, e.g. perborates, per = carbonates, perphosphates, persilicates, persulfates, hydrogen peroxide, sodium peroxide and the like. As will be appreciated, particular circumstances may give rise to the use of a particular type of peroxide compound, e.g. For example, considerations related to compatibility, bleaching, active oxygen content, etc. may matter which compound is used. In each case, particularly favorable results are obtained from the use of the alkali metal perborate such as sodium perborate, as compounds of this type have been found to allow the best possible results in bleaching effect, concentration efficiency and the like.

The present invention further contemplates the use of the cationic plasticizer and / or peroxide compounds in blends containing two or more, the advisability of thus proceeding primarily depending upon the manufacturer's requirements. In each case, this particular auxiliary constitutes an effective means for the manufacturer to capitalize on the favorable properties which characterize each of a variety of cationic and / or peroxygen compounds. When provided in the form of a simple bleach product, the ingredients involved may simply comprise a mixture of the peroxide compound and the cationic compound in the relative molar amounts indicated. Other constituents may be included in smaller amounts, i.e. from about 0 to about 5 and preferably from about 0.1 to about 3 weight percent of the product, such constituents including, without limitation, phosphates for pH control, olfactants, optical brighteners and dyes, etc. Where the bleach product is contemplated manufactured in tablet form, to facilitate the decay of the tablet, materials of such types as corn starch are added. Possible constituents of the foregoing type will be described in more detail below.

The present product is particularly favorable in that it allows to provide a fabric or fabric product with a softer grip, improved absorbency, persistent whiteness, better stain removal and elimination of static electricity in synthetic fabrics and the like. Discoloration and yellowing of substances, as well as the shortening of the useful life of substances which can normally be attributed to bleaching compounds by aging, are eliminated by the present product.

10: 1 - 1: 1 weight ratio of inorganic peroxygen bleach: cationic plasticizer proves to be most effective as an excellent multifunctional treatment product capable of imparting 25 better softness, bleaching and antifouling properties to the thus treated fabrics. However, favorable results have also been obtained where the weight ratio of bleach: cationic plasticizer is 17: 1 - 1: 4. The amounts of each component can be varied to prevent bleaching, softening and antistatic effects.

30

The process for treating substances with the present emollients does not depend on the temperature and can be very well carried out with cold or hot washing solutions. The process can also be carried out using water of a reasonable degree of hardness, although the use of softer wash water is of course preferred.

The softening bleaching and pendant antifouling product of the present invention may also contain minor amounts of brightening agents, bleaching, germicides, perfumes, diluents, or other additives which do not affect the product's softening, whitening and pendant antifouling properties.

This product is preferably prepared by dry mixing the ingredients to produce a free flowing powder. Peroxygen bleaches and the cationic plasticizer can be added in particulate form to the wash water simultaneously with the organic detergent or builder-containing detergent. However, it can also be dry mixed with spray-dried detergent or builder-containing detergent powder prior to addition to the wash water. The present product may be granular or powdered or it may be pill form or other suitable form. The amount of cationic plasticizer calculated on the total weight of the detergent product may be $ 3-20; and the amount of per = oxygen bleach may amount to approx. $ 5-50 and preferably $ 20-40 of the total weight.

The invention has so far found its greatest use in the softening and bleaching of cotton fabrics, fabrics made from other cellulose fibers, e.g. rayon or other textile fibers, f.

20, for example, nylon, silk, wool, polyethylene terephthalate, cellulose acetate, acrylonitrile polymers or copolymers or mixtures of two or more of these fibers (e.g., cotton-polyester blends). This softening-bleaching and adhesive-antagonizing product can be applied to the fabric in a water bath, either during the wash period at wash 25 or as a special and separate softening and bleaching operation. Since this softening-bleaching product is compatible with anionic and nonionic detergents, it is preferably added to the wash water during washing. In use, 90 g of the softening-bleaching product is added to an automatic washing machine or similar treatment container 30 containing 35 l of water and with a usual cloth portion (about 6-8 pounds). However, larger or smaller amounts can be used to achieve the desired degree of softness, whiteness and antistatic properties depending on the water temperature, the hardness of the water, the amount of water and the amount of clothing, etc.

The following examples are intended to illustrate the present invention. All parts are parts by weight unless otherwise indicated. In the examples, the pressure is atmospheric pressure unless otherwise indicated.

The individual components are dry mixed and the resulting product is used in the washing of clothes. Several samples of cotton terry, PP cotton and polyester / PP cotton (PP = Permanent Press finish) are subjected to five consecutive 10-minute washes in water with a water hardness of 150 ppm at 48.8 ° C with a powerful acting detergent containing 10 $ sodium linear tridecylbenzenesulfonate, 25 2 $ C - C - 3 fatty alcohol with an average of 11 ethyl oxide groups, 2 $ mixed sodium coconut / tallow fatty acid soap, 35 $ pentane sodium tripolyphos = phate, 7 $ sodium silicate (Na 2 O: SiO 2 ratio 1: 2 , 35), $ 0.5 sodium = carboxymethyl cellulose and the rest sodium sulfate plus 90 g of the above product.

30

The final softness rating of the samples was 10 ++ on a scale of 1-10, with 1 denoting no softness and 10 denoting excellent softness, a value of 5 being required for marginal softness and 8 denoting desirable softness. The antistatic effect on the synthetic substance 35 was very good.

Comparative experiments performed with detergent alone, detergent plus plasticizer and detergent plus chlorox bleach gave the following results: g 150992

Detergent + chlorox bleach 5 rings - powerful for hanging

In addition, the detergent cleansing effect and ability to remove stains was increased in the presence of the present product.

Thus, it is clear that the concomitant use of the cationic plasticizer, especially of the quaternary ammonium type, and the per = 15 oxygen bleach gives a completely unexpected synergistic cleaning effect, increasing its softening properties.

The weight ratio of peroxygen bleach to cationic plasticizer herein is 2.5: 1.

Example 2

The Arosurf TA-100 content of Example 1 is reduced to $ 5, the sodium = perborate content is increased to $ 35 and the spray dried base grains are reduced to $ 60.

Fabric treated in accordance with the procedure of Example 1 with this product, which represents a bleach to bleach weight ratio of 7: 1, achieved a softness rating of 8, a very good antistatic effect and excellent stain removal.

Thus, it is clear that changing the ratio of bleach to plasticizer within certain boundaries gives varying degrees of softness and stain removal.

Example 5 35 9 150992

The washing method of Example 1 was used except that the fabric was subjected to one 10 minute wash period using 95 g of the aforementioned powerful detergent plus 10 g of plasticizer and 20 g of sodium perborate (a ratio of bleach: cationic compound of 2: 1) on different stains using 4 specimens stained with blueberry pie filling, 4 specimens stained with clay, 4 specimens stained with potted soil, 1 strip of multi-stained fabric and 4 terry towels with the following results: 10 The efficiency of stain removal is determined by reflection coefficient readings, Rd (anti-re-precipitation) on the fabric, using a Gardner Color differential meter, wherein higher Rd values are indicative of increased whiteness; Rb (fluorescence) measures clarity and higher values indicate greater whiteness, a = redness (+), green (-); and b = blueness (-), yellow (+).
