Abstract: Higher homologues of hydrocupreine or of the quinatoxins, e.g iso-octyl hydrocupreine or iso-amyl hydrocupreine are used in very small quantities in admixture with carbocyclic acids, other than benzoic acid, or their derivatives including those of benzoic acid, as sterilizing agents in the preparation of sterilized soaps.  The carbocyclic acids used include cinnamic acid, and their derivatives include the esters or the hydroxy acids, e.g. p-oxybenzoic acid, salicylic acid and the methyl, ethyl or propyl esters of benzoic acid.  The mixture may be used by dissolving it in materials such as oils, fats which are used in the manufacture of the soap.ALSO:Higher homologues of hydrocupreine or of the quinatoxins, e.g iso-octyl hydrocupreine or iso-amyl hydrocupreine are used in very small quantities in admixture with carbocyclic acids, other than benzoic acid, or their derivatives including those of benzoic acid, as sterilizing agents for organic matter or substances containing it. The carbocyclic acids used include cinnamic acid, and their derivatives include the esters or the hydroxy acids, e.g p-oxybenzoic acid, salicylic acid and the methyl, ethyl or propyl esters of benzoic acid.  The sterilizing agent may be used in solution in water, alcohols, glycerine, fats, petroleum or other oils, e.g. paraffin, and carbon tetrachloride.  The carbocyclic acid or derivative may be added to the extent of 1-5 per cent of the oil and the quinatoxine or hydrocupreine to the amount of one part in 4000 of the oil.  The mixture may be employed for the sterilization in the cold.  The substances treated include food such as fruit or canned fish or fruit, beer and other alcoholic beverages, animal foods, liquids and other substances used for medical, surgical or veterinary purposes, and adhesives, sizes, starch paste, sewing thread, silk, catgut, hides, furs and tobacco.  The mixture may be used for the destruction of vermin and insects.  The mixture may be used in preparing face creams and other cosmetics, perfumes, tooth pastes, brilliantine, sterilized soaps, &c., by dissolving it in a bass material such as oils, fats, or glycerine, and then adding the perfume and other ingredients which may be dissolved in alcohol. Specification 339,602, [Class 49, Food &c.], is referred to.ALSO:Higher homologues of hydrocupreine or of the quinatoxins, e.g iso-octyl hydrocupreine or iso-amyl hydrocupreine are used in very small quantities in admixture with carbocyclic acids, other than benzoic acid, or their derivatives including those of benzoic acid, as sterilizing agents for animal foods.
