Abstract

An insecticidal concentrate consists of a suspension of small particles of solid dichlordiphenyltrichlorethane in a concentrated aqueous solution of a wetting agent. The preparation is diluted with water before use. According to an example, Teepol X (Registered Trade Mark), which is an aqueous solution of higher alkyl sulphates, is evaporated until it begins to gel. Dichlordiphenyltrichlorethane is then added and the heating is continued until the added compound has melted. The two substances are mixed thoroughly and the mixture is allowed to cool. Water is stirred into the resulting opaque gel to produce a product containing 12.5 per cent. of dichlordiphenyltrichlorethane. Specification 547,874 is referred to.
