Abstract

A mixture of water-soluble meta- and pyrophosphates in which the pyrophosphate is substantially more than 10 per cent of the metaphosphate is added to known cleansing or penetrating agents, other than per-compounds, or to the liquids used in dyeing or for the treatment of textiles, leather, or other organic raw materials or intermediate products. Phosphates of sodium and of organic bases, e.g. triethanolamine, cyclohexylamine, and amino - propandiols are specified. Suitable cleansing and like agents are soda, waterglass, borax, borates, alkali phosphate, soaps. p There may be added soap substitutes, e.g. alkali salts of sulphonated oils or of sulphonated fatty alcohols, foam-producing agents, superfatting agents, organic solvents, enzymes, and abradants, e.g. finely ground sand. For example, 0.2 gm. of soda is used with 0.3 gm. of a mixture of 30 or 50 parts of sodium pyrophosphate and respectively 70 or 50 parts of sodium metaphosphate. Specifications 378,345, [Group III], 424,959, 435,861, 437,128, and 438,063 are referred to. According to the Provisional Specification any mixture of meta-and pyro-phosphates may be used alone or with other cleansing and like agents, and oxygen - yielding substances, e.g. hydrogen peroxide, perborates, persulphates, with or without stabilizing agents, may be added to impart bleaching properties.ALSO:A mixture of water-soluble meta- and pyrophosphates in which the pyrophosphate is substantially more than 10 per cent of the meta-phosphates is added to known cleansing or penetrating agents, other than per compounds, or to the liquids used in dyeing or for the treatment of textiles, leather or other organic raw materials or intermediate products.
