Frequently Asked Questions
What is propylene glycol monostearate used for?
Propylene glycol monostearate (CAS 1323-39-3) is the monostearate ester of propylene glycol, used as an emulsifier, opacifier, and emollient in cosmetics such as creams and lotions, and as an emulsifier in processed foods.
Is there a difference between propylene glycol and propylene glycol monostearate?
Yes. Propylene glycol (CAS 57-55-6) is a small diol, while propylene glycol monostearate (CAS 1323-39-3) is its ester with stearic acid, a waxy emulsifier with formula C21H42O3. They function very differently: one is a solvent/humectant, the other a surface-active emulsifier.
What is the chemical formula of propylene glycol monostearate?
Its molecular formula is C21H42O3, the ester of propylene glycol with one stearic-acid chain. The "Pure" designation indicates a high-monoester grade; the assay is confirmed on the CoA.
What does propylene glycol monostearate do as an emulsifier?
As a lipophilic emulsifier it stabilizes oil-in-water systems and modifies texture and opacity in creams, lotions, and processed foods. It is typically used with a co-emulsifier to balance the HLB of a formulation.
What bulk packaging and grades are available for propylene glycol monostearate pure?
