Lead Stearate is a toxic lead-containing compound whose manufacture, import, export, sale and use are restricted or prohibited in many countries and product categories.
Supply is therefore subject to:
- Applicable Indian regulations
- Destination-country chemical laws
- Customer restricted-substance requirements
- Approved industrial end use
- Workplace lead-control capability
- Environmental and waste-management arrangements
- Product availability
- Current Safety Data Sheet
- Required permits and documentation
- Commercial and logistics feasibility
Lead Stearate must not be used in food, pharmaceuticals, nutraceuticals, animal feed, cosmetics, toys, children’s products, medical devices, drinking-water-contact products or unrestricted consumer goods.

Lead Stearate Description
Lead Stearate is the lead salt of stearic acid and belongs to the group of heavy-metal soaps. It is commonly represented chemically as Lead Distearate or Pb(C₁₈H₃₅O₂)₂. Commercial Lead Stearate may contain lead salts of more than one fatty acid because industrial stearic acid commonly contains a mixture of stearic and palmitic acids.
Vinipul Inorganics Pvt. Ltd. accepts Lead Stearate enquiries only after reviewing the industrial application, destination market, required quantity and buyer’s ability to meet applicable legal and safety requirements.

Lead Stearate and Calcium Stearate Difference
| Parameter | Lead Stearate | Calcium Stearate |
| Metal Ion | Lead | Calcium |
| CAS Number | 1072-35-1 | 1592-23-0 |
| Main Historical Role | Lead-based PVC stabilisation and lubrication | Lubrication, acid scavenging and Calcium-Zinc stabilisation |
| Toxicity Profile | Toxic lead-containing compound | Lower-hazard metallic stearate, grade dependent |
| Regulated Uses | Highly restricted | More widely used in modern applications |
| Food / Pharmaceutical Use | Not suitable | Possible only with an approved compliant grade |
| Modern PVC Position | Largely phased out or restricted | Common in lead-free stabiliser systems |
Calcium Stearate is not always a direct replacement. The full stabiliser formulation must be redesigned.
