Abstract
A detergent composition is provided having good cleaning effectiveness while simultaneously imparting to the material treated a soft feel and/or good conductivity for static electricity, and comprising a mixture of surfactants of which: A. from 30 to 90% by weight is a surfactant selected from the group consisting of nonionic surfactants, amphoteric surfactants, and mixtures thereof; and B. from 10 to 70% by weight is a surfactant mixture comprising at least one anionic surfactant and at least one cationic surfactant in a charge ratio anionic surfactant to cationic surfactant within the range from about 0.60 to about 0.90, suitably within the range from 0.70 to 0.95, and preferably within the range from about 0.75 to about 0.90.
Claims16
A detergent composition imparting a good antistatic effect and a good softening effect, consisting essentially of a mixture of surfactants of which
- a. from 30 to 90% by weight is a nonionic surfactant having the formula:
- RA (C.sub.n H.sub.2n O).sub.x H
- wherein
- R is a hydrocarbon group selected from the group consisting of alkyl groups having from about eight to about twenty-two carbon atoms, and mono-alkyl phenyl groups having a total of from about four to about twenty-four carbon atoms in the alkyl groups;
- and
- A is selected from the group consisting of oxygen, sulfur, amido, carboxylic acid, sulfoxide and sulfonic groups;
- n is a number from 2 to 4;
- and
- x is a number from 4 to about 40;
- and
- b. from 10 to 70% by weight is a surfactant mixture comprising at least one anionic surfactant and at least one cationic surfactant in a charge ratio anionic surfactant to cationic surfactant within the range from about 0.60 to about 0.98;
- the anionic surfactant having the general formula:
- R(OC.sub.n H.sub.2n).sub.p OSO.sub.3 H
- wherein:
- R is a hydrocarbon group selected from the group consisting of alkyl groups having from about eight to about twenty-two carbon atoms, and mono-alkyl-substituted phenyl groups having a total from about six to about eighteen carbon atoms in the alkyl groups;
- (OC.sub.n H.sub.2n).sub.p represents an alkylene glycol chain where n is selected from the group consisting of 2, 3 and 4 and p is a number from 1 to 10;
- and salts thereof;
- and the cationic surfactant being a quaternary ammonium surfactant having the formula:
- R.sub.1 R.sub.2 N.sup.+ (CH.sub.3).sub.2 X.sup.-
- wherein:
- R.sub.1 and R.sub.2 are selected from the group consisting of alkyl and alkoxy-2-hydroxy propylene groups having from about six to about twenty-two carbon atoms;
- and
- X is an anion.
