Zinc Stearate (ZS)

Zinc Stearate (ZS)

Zinc stearate is a zinc distearate. Zinc stearate can be used as excipients, such as lubricants for tablets and capsules. Its hydrophobicity can effectively prevent the tablet from getting damp. In addition, zinc stearate is used in the processing of non-toxic PVC products, which has a synergistic effect with calcium stearate and barium stearate, and can effectively improve the light stability of PVC products.
