of wool, a mixture exuded by the sebaceous and sudoriferous glands in the skin of sheep. Its appearance and consistency resemble melted lard, and its wool-grease content and chemical composition depend on the breed, sex, and individual characteristics of the sheep, as well as on the feeding and tending conditions.
In merino sheep the amount of wool grease in the wool is 30–40 percent; in semifine fleece sheep, 12–20 percent; and in coarse-wool sheep, approximately 4 percent. The suint lubricates and protects the wool from moisture, dirt, and other external factors and promotes better maintenance of the physical and mechanical properties of the wool fiber. Suint is used to make soap, potash, lanolin, lubricating oils, and fertilizers.
