Abstract

A coated detergent tablet of good mechanical strength and water-dispersibility comprises a mass, particularly a pressed mass, of individual detergent particles enclosed in a film of organic water-dispersible binder which is a homopolymer of vinyl alcohol or a copolymer of vinyl alcohol with a copolymerizable monomer, obtained by hydrolysis of the corresponding polymer ester, particularly the acetate. Preferably the coating constitutes 1.5-6.0% by weight of the tablet, is of average thickness 1-5 mils., penetrates no more than 10 mils. into the surface of the mass and has a tensile strength of at least 150 p.s.i. Liquid solutions or dispersions of the binder may be used; where liquid solutions are employed the viscosity requirement in order to prevent impregnation of the detergent mass is at least 30 centipoises at 20 DEG C. The binder may contain 5-25% by weight of a plasticizer which may be glycerol, a lower glycol, glycerol borate, sorbitol, a polyoxyethylene compound, an alkyl aromatic hydroxy compound, or an alkyl phosphate; perfumes. dyes, pigments and fillers may be included. The sole detergent specified is alkyl benzene sodium sulphonate which is mixed with sodium tripolyphosphate, sulphate and silicate builders and sodium carboxy methyl cellulose, pressed at 50 p.s.i. (3-100 p.s.i. generally) and coated with polyvinyl alcohols of 20-40% residual acetate content and degrees of polymerization of 20-150.
