Polysorbate 20 (Tween 20) is a hydrophilic non-ionic surfactant (CAS 9005-64-5) obtained by esterification of sorbitol with vegetable oil fatty acids. It blends oils, fragrances and essential oils into aqueous systems, creating clear, stable formulations — from micellar waters to body oils.

CAS number: 9005-64-5  ·  INCI: Polysorbate 20

FAQ

What is the CAS number of Polysorbate 20?

CAS 9005-64-5, also known as Tween 20.

What is the INCI name?

Polysorbate-20.

What is the HLB value of Polysorbate 20?

Approximately 16.7 — a high-HLB hydrophilic emulsifier suited to O/W systems.

What is the difference between Polysorbate 20 and 80?

Polysorbate 20 has a shorter (laurate) fatty chain and higher HLB (~16.7); Polysorbate 80 (oleate) is more lipophilic (HLB ~15). Choose 20 for lighter oils, 80 for heavier lipophilic actives.

What is the recommended dosage?

Typical use level 2%–10% depending on oil load and formula type.
