COMPOSITIONS OF CELLULOSE FABRIC CONDITIONERS This is a continuation in part of the pending application of E.U.fi. Series No. 08 / 236,914, filed on April 29, 1994.

FIELD OF THE INVENTION The present invention relates to fabric conditioning compositions for use in the rinse cycle of laundry processes, for imparting softness as well as appearance benefits to the fabrics, said compositions comprising fabric softener active (s), cellulases and antioxidant and / or chelator.

BACKGROUND OF THE INVENTION Fabric conditioning compositions, in particular fabric softening compositions which are to be used in the rinse cycle of laundry processes, are well known. Typically, said compositions contain a water-soluble quaternary ammonium fabric softening agent, the most commonly used being long chain dialkyl ammonium chloride. The anti-roughness effect of the cellulase on the fabrics is known, v.gr-, from FR 2 481 712 or GB-fl-1 368 599, as well as its fabric care benefits, described, e.g., in EPfl 269 168, all incorporated herein in their entirety by reference. However, cellulase has been described primarily for use in detergent compositions to be used in the main wash cycle of laundry washing processes, and has found some commercial application in this context. In spite of said teachings, the use of cellulases in fabric softener compositions added to the rinse apparently has not been commercially dedicated so far. The reason may be that one of the potential points to be resolved is to provide acceptable stability of the cellulase in said compositions during storage. Another reason may be potential points to be resolved around the effectiveness of the use of the cellulase in the rinse cycle after a normal washing cycle with detergent. Such conditions are typically of shorter duration and lower temperatures than those used in the wash cycle, and there is concern about the potential for damage to the fabrics if the cellulase conditions of activity too high are satisfied by the conditions of use of the cycle. rinsing and / or carrying out cellulase activity from the use of detergents containing cellulase in the rinse cycle. It has been found that fabric softener compositions added to the rinse can be formulated to contain cellulase to provide cellulase activity during normal use conditions that is within certain limits to provide fabric softening benefits with an acceptable impact on the use of the fabric. cloth. The present invention provides fabric softening compositions containing cellulase in which the cellulase is further stabilized for storage by the addition of antioxidants and / or chelators. This allows the formulation of fabric softening compositions in all the typical pH scale of fabric softening agents, including pH from 5 to 7 for traditional fabric softening actives, while achieving both effectiveness and fabric safety benefits after storage. dragged on.

Suitable cellulases are described, for example, in GB-fi-2 075 028, GB-A-2 095 275 and DE-OS-24 47 832, all incorporated herein by reference in their entirety. Examples of said cellulases are cellulases produced by a strain of Humicola insolens (Humicola grísea var. Thermoidea), particularly by a strain of Humicola DSN 1800, and cellulase-producing fungus 212 belonging to the genus Ñeromonas, and cellulase extracted from the hepatopancreas of a mollusc. marine (olabella auricola Solander).

Cationic or non-ionic fabric softening agents: Preferred fabric softening agents for use in the compositions of the present invention are quaternary ammonium compounds or precursors having the formula (I) or (II), below: (D (p) O is -O-C (O) - O C (0) -0- or -N 4 -CX ()) -NR 4 -; R is (CH2) n -0-T2 or T2 or T3, R2 is (CH2) «-0-T * or TS or R3; R3 is Ci-C "alkyl or Ci-C4 hydroxyalkyl or H; R * is H or Ci-C4 alkyl or Ci-C * hydroxyalkyl; Ti, t, t3, T *, T5 are (the same or different) C11-C22 alkyl or alkenyl; n and rn are integers from 1 to 4; and X- is an anion compatible with the softener. The chain Ti, T, T3, T *, T * of alkyl, or alkenyl, must contain at least 11 carbon atoms, preferably at least 16 carbon atoms. The chain must be straight or branched. Sebum is a convenient and inexpensive source of long chain alkyl or alkenyl material. The compounds where Ti, T2. t3, T *, T5 represent the mixture of long chain materials typical for tallow are particularly preferred. Specific examples of quaternary ammonium compounds suitable for use in the fabric softening compositions herein include: 1) N, N-di (tallowyloxyethyl) -N, N-dimethyl-ammonium chloride 2) N, N -di (seboyl-oxy-ethyl) -N-rnetyl, N- (2-hydroxy-ethyl); 3) N, N-di (2-tallowoyloxy-2-oxo-ethyl) -N, N- "dimethylaronium chloride; 4) N, Nd? (2-tallowyloxyethylcarbonyl-oxyethyl) -N, N-dimethylammonium chloride; 5) N- (2-tallowoyloxy-2-ethyl) -N- (2-tallowoxy-2-oxo-ethyl) -N, N-dimethylammonium chloride; 6) N, N, N-tri chloride ( seboyl-oxy-ethyl) -N-methyl-a onium; 7) N- (2-tallowoyloxy-2-oxoethyl) -N- (talloxyl-N, N-dimethylammonium chloride; and 8) 1,2- Chloride diploboyl-3-trimethylammonium-propane, and mixtures of any of the above materials, of which, compounds 1-7 are examples of Formula (I), compound 8 is a compound of Formula (II). Particularly preferred is N, N-di (tallowyloxyethyl) -N, N-dimethyl ammonium chloride, wherein the tallow chains are at least partially unsaturated.The level of unsaturation of the tallow chain can be measure by the iodine value (VI) of the corresponding fatty acid, which in the present case should preferably be in the range of 5 to 100 with two categories of compounds being distinguished, having a VI of less than or greater than 25. In fact, for compounds of Formula (I) made from tallow fatty acids having an IV of 5 to 25, preferably 15 to 20, it has been found that a cis / trans isomer weight ratio greater than about 30/70, preferably greater than about 50/50 and most preferably greater than about 70/30 provides optimum concentration ability. For compounds of Formula (I) made from tallow fatty acids having a Vi greater than 25, the ratio of cis to trans isomers has been found to be less critical unless very high concentrations are required.
