  • Patent number: 5582638
    Abstract: A thickening agent which is based on at least one synthetic phyllosilicate which contains at least one additive from the group of organic phosphorus compounds comprising the following:a) phosphonic acids with formula ##STR1## b) phosphinic acids with formula ##STR2## c) thiophosphinic acids with formula ##STR3## d) diesters of phosphorous acid with formula HO--P(OR).sub.2 e) diesters of phosphoric acid with formula ##STR4## f) diphosphonic acid with formula ##STR5## in which R is an alkyl or hydroxyalkyl group with 1 to 22 C atoms or an aryl or hydroxyaryl group with 6 to 12 C atoms and R' is an alkylene group with 2 to 22 C atoms.
