FARRIC TREATMENT COMPOSITION

This invention relates to a fabric treatment composition for treating fabrics during the rinse step of a fabric laundry process, and to a method for using said composition. In particular, the invention relates too a fabric treatment composition comprising a fabric—-softening material, which is preferably a cationic fabric softening material and antimicrobial agent.

It is known that fungal growth can develop on 10 fabrics stored under certain physiological conditions, auch as in a humid atmosphere or where there is a poor - air circulation. These growth can damage the fabrics by causing them to discolour. The fabrics can also develope an unpleasant smell. It has been found that 16 the discolouration or staining of the fabrics is difficult to remove either by normal laundering or after treatment with a strong bleaching agent.

It has previcusly been proposed (EP 86 423, Henkel

KGaA) to incorporate specific antimicrobial subtances in fabric treatment compositions.

We have now surprisingly discovered that bensximidazolyl-alkyl-carbamates, when combined with fabric—softening materials into a fabric treatment composition, are particularly effective in inhibiting 3 fungal growth on fabrics which have been rinsed with said fabric treatment composition.

The incorporation of benzimidazolyl—-alkyl-carbamates in textile treatment compositions according to the invention has also been found advantegeous in that benzimidazolyl—alkyl—carbamates are: i. effective against a wide range of micro-organisms, particularly fungi “ 2. active during the life of the products: 18 3. ot low mammalian toxicity and non-toxic to humans "at the concentrations useds 4, colourless and pdourlessy 5S. effective at low concentrations} b. inexpensive and easy to apply: 7. resistant to sunlighty a. not affecting fabric handle or strenghts 9. compatible with water—repellent and flame—retartdant agents, dyes and other tewtile

Thus, according to the invention there is provided 8 a fabric treatment composition comprising a softening material and a henzrimidazolyl-alkyl-carbamate. " Preferably the softening material comprises a cationic ’ fabric softener.

Renzimidazolyl—-alkyl—-carbamates are well-known fungicides for use in agriculture, It also been suggested in Japanese patent application 49 093X Q37 {Yoshitomi) to treat textiles with a composition containing Me-2-henzimidazole-carbamate in a solvent.

This treatment, however, requires a separate processing 158 step for applying the henzimidazilyl-alkyl-carbamate and a. further separate processing step far removing the undesirable solvent compound.

The henzimidazolyl-alkyl-carbamate as used in a 20 textile treatment composition of the invention preferably of the following formula:

With a machine of this type, the fabrics will normally have been previously washed in the same tub of the machine, \ aor they may be placed in the tub specifically for rinsing. When previously washed, they will have at least some of the wash liquiaor containing a detergent active still adsorbed on or otherwise associated with them, the running water then serving to flush this wash liquior out of the fabrics. The rinse water running into the tub will be substancially free of any detergent actives. The composition can he added to the

Aqueous compositions were prepared according to the formilations in the fnllowing tables. The compositions were prepared by co-melting the cationic fabric—softening agent and a benzimidazolyl-alkyl-carbamate at go°C. The co-melt thus formed was added to water at go"c to form a dispersion. In examples containing 2.5% and 85.0% carbendazim respectively, the henzimidazolyl-alkyl-carbamate WARS post-dosed to a 10 dispersion containing the cationic fabric—saftening agent. . The compositions were tested by the following me: thod .
