In wood pulp production arena, SLS powder is produced as a result of sulphite pulping process. Sodium lignosulphonate powder is used as an important ingredient during formulation of dust controlling agent, concrete admixture, water dispersing agent and animal feed additive. SLS powder is also effective in decreasing surface tension of water to improve its dispersing property. It also possesses good binding property. Non toxic content, strong buffering property, low molar mass and biodegradable nature are some of its key aspects.
