Definitions
- a detergent composition of this type is described in European Patent Specification EP-A-213730 (Unilever) according to which the composition contains both a fabric softening agent and a water-soluble nonionic cellulose ether of a selected class, defined in terms of HLB, gel point and the nature of the substituents on the cellulose ether.
- the described compositions may be prepared by including the cellulose ether in a slurry with other ingredients and then spray-drying or it may simply be dry-mixed with other ingredients. While successful results can be obtained with these methods of incorporation we have now surprisingly discovered that better fabric softening results can be obtained if the cellulose ether is added in the form of a particulate additive which also contains the fabric softening agent.
- US Patent Serial No 3 920 561 describes a rinse conditioner containing a highly substituted methyl cellulose ether. Good soil release benefits are claimed when the composition is used in the absence of deterging amounts of anionic detergent.
- the fabric softening material is preferably a cold water-insoluble material, that is a material having a solubility at 20°C of less than 10 g/l in water at a pH value of about 6 or a material which will form an insoluble calcium salt in hard water.
- Highly preferred water-insoluble quaternary ammonium compounds are those having two C12-C24 alkyl or alkenyl chains, optionally substituted by functional groups such as --OH, --O--, --CONH and --COO--.
- R1 and R2 each independently represent a C12-C22 alkyl group, preferably straight-chained and R3 is methyl or ethyl.
- Suitable amines include: didecyl methylamine; dilauryl methylamine; dimyristyl methylamine; dicetyl methylamine; distearyl methylamine; diarachidyl methylamine; dibehenyl methylamine; arachidyl behenyl methylamine or di (mixed arachidyl/behenyl) methylamine; di (tallowyl) methylamine; arachidyl/behenyl dimethylamine and the corresponding ethylamines, propylamines and butylamines.
- soaps include sodium stearate, sodium palmitate, sodium salts of tallow, coconut oil and palm oil fatty acids and complexes between stearic and/or palmitic fatty acid and/or tallow and/or coconut oil and/or palm oil fatty acids with water-soluble alkanolamines such as ethanolamine, di- or tri-ethanolamine, N-methylethanol- amine, N-ethylethanolamine, 2-methylethanolamine and 2,2-dimethyl ethanolamine and N-containing ring compounds such as morpholine, 2'-pyrrolidone and their methyl derivatives.
- water-soluble alkanolamines such as ethanolamine, di- or tri-ethanolamine, N-methylethanol- amine, N-ethylethanolamine, 2-methylethanolamine and 2,2-dimethyl ethanolamine and N-containing ring compounds such as morpholine, 2'-pyrrolidone and their methyl derivatives.
- the fabric softening agent is a mixture of soap and either a cationic fabric softening agent or a fatty amine.
- the level of fabric softening additive in the composition is such that the fabric softening agent occupies more than 0.5% by weight, such as more than 2% by weight in order to provide a noticeable fabric softening benefit. Not more than 50% by weight, preferably not more than 20% by weight of fabric softener is present in the composition to leave room in the formulation for other ingredients.
- the fabric softening agent is a soap
- a level of less than 10% by weight of the composition is sufficient to provide a fabric softening benefit.

Claims (8)
- Un additif en particules adoucissant le linge pour compositions détergentes, comprenant en tant qu'ingrédient unique ou principal, un mélange intime d'un éther de cellulose soluble dans l'eau et d'un agent organique adoucissant le linge, dans un rapport en masse allant de 1 pour 1 à 0,06 pour 1, caractérisé en ce que l'éther de cellulose non ionique est une éthyl hydroxyéthyl cellulose ayant un HLB compris entre 3,3 et 3,8 et un point de gel compris entre 33°C et 56°C.
- Un additif adoucissant selon la Revendication 1, dans lequel l'éther de cellulose a un degré de substitution allant de 1,9 à 2,9 substituants par anneau anhydroglucose.
- Un additif adoucissant selon la Revendication 1, dans lequel l'éther de cellulose a un degré moyen de polymérisation en masse allant de 50 à 1.200.
- Un additif adoucissant selon la Revendication 1, dans lequel l'éther de cellulose contient de 0,9 à 2,0 groupes éthyle et de 0,1 à 2,0 groupes hydroxyéthyle par anneau anhydroglucose.

- Un procédé de préparation d'un additif adoucissant selon la Revendication 1, ledit procédé comprenant les étapes consistant à :(i) faire fondre l'agent adoucissant le linge et y disperser l'éther de cellulose afin de former un mélange liquide, et(ii) faire refroidir ledit mélange liquide afin d'obtenir un mélange solide.
- Un procédé selon la Revendication 6, comprenant en outre l'étape consistant à broyer et tamiser le mélange solide à une taille de particules allant de 50 à 1000 micromètres.
- Une composition de traitement du linge comprenant :(i) de 2 % à 50 % en masse de matériau détergent actif anionique non savonneux ou un mélange de celui-ci avec d'autre matériaux détergents actifs non savonneux; et(ii) de 1,0 % à 53 % en masse de l'additif en particules adoucissant le linge selon la Revendication 1.
