The correct use of surfactants will greatly improve the efficiency of soaking processes. A balanced surfactant system possessing high dispersing / wetting and fat dissolving properties is recommended. Such agents are contained in the BORRON range of surfactants. The use of compatible surfactants in combination with enzymatic soaking agents PELLVIT produces a synergistic effect which greatly enhances the soaking process.
Excessive fat can cause problems in Hair Saving and hair pulping lime processes. Raw fat can contaminate hair to a point where the immunisation is impaired and very wet, sloppy hair is recovered during the HS process. This situation can be made worse by the use of some types of temporary preservation which makes the fat more insoluble.
Calcium soaps formed during liming can prevent even penetration of liming liquors producing drawn areas on the pelt.
