§1What this business is

Sodium stearate (from stearic acid and soda ash) is reacted with magnesium chloride solution; the magnesium stearate that settles out is filtered, washed, dried, powdered and packed. It is sold as a tablet and capsule lubricant to pharma companies, and as an additive to paint, PVC, rubber, cosmetics and soap makers. Buyers test each batch, so consistent quality matters most.

Capacity: 0.40 MT a day, 120 MT a year; 72 MT in year 1 at 60%.

§2Is it right for you?

Who it is for

A chemist or chemical trader with contacts in pharma, PVC or paint companies.

Who it is not for

Someone without laboratory testing ability.

Advantages

  • Used across pharma, paints, PVC, rubber and cosmetics
  • Simple batch chemistry
  • Steady repeat orders once approved
  • Can add calcium and zinc stearate on the same plant

Drawbacks

  • Pharma buyers demand IP/BP-grade quality and audits
  • Stearic acid price swings
  • Eight months to start production (report)
  • Boiler and drying need careful operation

Skills you need

  • Batch reaction and filtration
  • Lab testing (MgO content, fatty acids)
  • Boiler and dryer operation
  • B2B chemical selling

Why difficulty 4/5: Chemical process, lab testing and strict buyer specifications.

§3Market

Who buys

  • Pharmaceutical tablet and capsule makers
  • Paint, varnish and cement-paint makers
  • PVC pipe and compound makers
  • Rubber, cosmetics, soap and toothpaste makers

How it sells

  • Direct B2B supply after sample approval
  • Chemical traders and distributors

Good to know

  • The report says its main use is as a pharmaceutical excipient and lists paints, PVC, rubber, cosmetics, wire drawing, soap and toothpaste as other users.
  • Quality is to customer specifications.
