Claim 1
Independent Claim
122 words
A detergent composition for washing and softening fabrics consisting essentially of from 2% to 50% by weight of at least one detergent active material and, as a fabric softening agent, a semctite clay mineral which is a 2:1 layer phyllosilicate possessing a lattice charge deficiency in the range of 0.2 to 0.4 g equivs. per half unit cell, and which falls into the formula: (Si.sub.4-y Al.sub.y) (Al.sub.2-a-b M.sup.III.sub.a N.sup.II.sub.b)O.sub.10 (OH).sub.2 X.sup.I.sub.y+b in which M III is a trivalent metal ion, N II is a divalent metal ion, X I is a balancing exchangeable cation, y is O or a positive number less than 4, and a and b are positive numbers less than 2 such that y+b is from 0.2 to 0.4.
