MONTANE, sorbitan esters solubilizers and emulsifiers


Sorbitan esters, lipophilic solubilizers and emulsifiers

MONTANE™ range is comprised of different sorbitan ester grades that can be used to formulate water-in-oil emulsions for oral, topical and injectable formulations.

Lipophilic emulsifiers

MONTANE™ products are sorbitan esters.

These lipophilic surfactants are used as emulsifiers to formulate water/oil emulsions.

MONTANE™ products are stable in slightly acidic or basic media and are compatible with other surfactants.

They can be used alone or combined with MONTANOX™ to produce highly stable emulsions.

MONTANE™ products can be used in practically all emulsion formulations: creams, ointments, lotions, injectable preparations, etc.

A suitable grade for every application

The MONTANE™ range is composed of monoesters and triesters of lauric, stearate or oleic fatty acids. They are characterised by their HLB (hydrophilic-lipophilic balance) value.

Two pharmaceutical grades are available: PPI and PHA PREMIUM

  • The PPI grade is designed for injectable administration and products are manufactured according to the Good Manufacturing Practices “GMP part II” and comply with the EP and USP pharmacopoeia.
  • The PHA PREMIUM grade is designed for oral and topical administration and products are manufactured according to IPEC’s GMPs and comply with the EP and USP pharmacopoeia.
