  • Patent number: 5496379
    Abstract: A method of applying dye to keratin fibres comprises pretreating the fibres by contacting them with an alkaline solution of an amphoteric surfactant, and thereafter applying dye to the pretreated fibres from a dyeing solution substantially deficient of surfactant-type levelling agents. Also disclosed is a novel surfactant compound comprising an alkoxylated hydroxysulphobetaine of formula: ##STR1## where: R.sub.1 is a hydrocarbon group selected from the range C.sub.12 H.sub.25 up to C.sub.21 H.sub.43 ; andR.sub.2 and R.sub.3 are poly(alkylene oxide) groups, each having n alkylene oxide units, where 3.ltoreq.n.ltoreq.21.In another aspect, there is disclosed a method of applying dye to keratin fibres comprising contacting the fibres with a bath liquor comprising an alkaline solution of the above surfactant, and thereafter adding dye to the bath liquor and applying the dye to the fibres from the bath liquor.

  • Patent number: 5480587
    Abstract: A method of modifying an inorganic material which evolves gases and/or vapors at a temperature which is detrimental to the processing temperature of polymer or paper systems so that the modified material can be used as a fire retardant additive with that polymer or paper system. The method comprises the steps of: (1) providing a first material; (2) treating the first material to remove the portion which evolves gas which is detrimental to the processing of the polymer or paper system; and (3) combining a second material with the first material to create a modified material which does not evolve gas at a temperature which is detrimental to the processing of the paper or polymer system.
