RSF-AT-100 is a diluent that can be used with cationic and silicone softeners to reduce costs and improve performance. It is a non-ionic polymeric base that can be used on its own as a softener or blended with silicones and cationics. When used as a diluent, it improves softness and reduces yellowing. Using it can provide a cost savings of 10-20% compared to traditional recipes. It is suitable for exhaust and padding applications on fabrics like cotton and polyester.
