SPRAY CONTAINING AMPHOTERIC MATERIAL TO REDUCE MALODORS

摘要

Powder compositions usable to reduce malodours, and powder formulations from which can be made aqueous spray compositions usable to reduce malodours, each comprise, as a major ingredient, amphoteric material, for example sodium bicarbonate, potassium bicarbonate, or zinc oxide, together with one or more minor ingredients, in particular a drying agent, for example sodium sulphate. Other minor ingredients may be an ammonia-odour/sulphide-odour remover, for example ferrous sulphate or zinc sulphate, and an adsorbent, for example zeolite, in the case of a powder formulation; or a filler, for example potassium chloride, or an organic complexing agent, for example cyclodextrin, or a surfactant, in the case of a stock formulation.
