Suint

Wool belongs to the family of proteins (qv) called keratins. However, morphologically the fiber is a composite and each of the components differs in chemical composition. Principally the components are proteinaceous, although wool cleaned of wax, suint, and other extraneous materials acquired during growth contains small amounts of Hpids (stmctural and free), trace elements, and, in colored fibers, pigments called melanin. 

In wool scouring, the contaminants on the wool, mainly grease, dirt, suint, and protein material, are washed off the fiber and remain in the wastewaters either in emulsions or suspension (grease, dirt, protein) or in solution (suint). Centrifugal extraction of the wastewaters produces a grease contaminated with detergent and suint. This product is called wool grease.

Wool fat or suint.—The potash found in plants is obtained from the soil and the potash in the soil is one product of the decomposition of rocks which form the earth s crust. The potash which herbivorous animals—e.g. sheep—draw from the land is largely exuded as an oily sweat from the skin, and called, after the French, suint. In the first century of our era, Dioscorides called the mixture of wool fat and water oTowos, eesypus, a name which it retained up to the middle of the seventeenth century. CEsypus is mentioned several times by Ovid. In spite of its disagreeable smell it appears to have been used by the Boman ladies as one of their choice cosmetics. It is mentioned in N. Culpeper s Pharmacopoeia Londi-nensis (London, 1653), but it soon afterwards disappeared from the pharmacopoeia... 

The annual production of potash from suint in 1913 amounted to between five and ten thousand tons. 

To observe the role of chemical cues in the sexual behavior of males of small mammals, we can alter the odor of females. Hair is a great substrate for odor-carrying lipids. For example, the behaviorally active body odors of sheep reside in the wool fat, also known as suint. Removing hpids from the fur of female mice reduces the lipophilic odorants significantly. Hair near skin glands is often anatomically modified into osmetrichia to hold sebum on its cuticular surface (Miiller-Schwarze et al. 1977).
