Abstract
Abstract An antistatic composition particularly adapted for use on textiles, floor coverings, and related materials, comprising an aqueous liquid fluid medium, having a pH within the range of about 7 to 13 and containing as active ingredient an organic antistatic textile agent and from about 1 to 0.5 parts by weight of a humectant. The humectant may be either a nonionic humectant (such as glycerine) or an ionic humectant (including strong electrolytes such as calcium chloride). When the humectant is nonionic, there must also be present at least 0.01 part by weight of a strong electrolyte, i.e., the salt of a strong base and a strong acid.
