The handbook of soap manufacture

A practical manual presents the chemistry of saponification and the molecular makeup of fats and oils, then surveys raw materials, their bleaching and pretreatment. Detailed guidance on soap manufacture covers cold and boiled processes, pasting, graining, milling and finishing operations, including cleansing, neutralising, colouring, perfuming, shaping and drying. Separate sections treat toilet, textile and medicated soaps, essential oils and synthetic fragrances, glycerine recovery and purification, and analytical methods for raw materials, lyes, soaps and glycerine. The work concludes with industry statistics and tables of thermometric and density comparisons.
