Ointment of Methyl Salicylate, B.P.C, Contains 50 per cent by weight of methyl salicylate in a base of equal parts of beeswax and hydrous wool fat. 

The determination of methyl salicylate in Compound Ointment of Methyl Salicylate, B.P.C. (which contains 50 per cent with aromatics in beeswax and hydrous wool fat) and Non-Staining Ointment of Iodine with Methyl Salicylate, B.P.C. (see also p. 314) is the same as given above using 0 3 g and 3-0 g respectively. 

Hydrous Wool Fat (Lanolin). This is wool fat with 30 per cent of water. The moisture may be determined by direct drying of a thin layer in an oven at 100°, or preferably, by distillation with an immiscible solvent (p. 803). 

The unsaponifiables of woolwax, known as woolwax alcohols, are in considerable demand by cosmetic and pharmaceutical industries. Woolwax has a great affinity for water, of which it will absorb 25 to 30%. Refined woolwax is kneaded with water to produce a water-white, colorless oiiilmenL, known as hydrous lanolin or lanolin USP. Anhydrous lanolin is widely used in cosmetic creams, since it is readily absorbed by the skin. It is also used m leather dressings and shoe pastes, as a superfatting agent for toilet soap, as a protective coating for metals, etc. United States consumption of wool wax is about 1.5 million lb/year. 

While the formed-in-place or dynamic hydrous zirconium oxide membranes on porous stainless steel supports have been studied mostly for biotechnology applications, they have also demonstrated promises for processing the effluents of the textile industry [Neytzell-de-Wilde et al, 1989]. One such application is the treatment of wool scouring effluent. With a TMP of 47 bars and a crossflow velocity of 2 m/s at 60-70°C, the permeate quality was considered acceptable for re-use in the scouring operation. The resulting permeate flux was 30-40 L/hr-m. Another potential application is the removal of dyes. At 45 C, the dynamic membranes achieved a color removal rate of 95% or better and an average permeate flux of 33 L/hr-m under a TMP of 50 bars and a crossflow velocity of 1.5 m/s.
