🌿 Emulsifier Tween Series – also known as polyoxyethylated sorbitan fatty acid esters – offers versatile nonionic emulsification solutions.
✨ Core grades:
Tween 20 (CAS 9005-64-5): Lauric-acid based, highly hydrophilic, excellent for dispersing small amounts of oils or fragrances in aqueous systems. Common in toners, serums, food & pharma formulations.
Tween 80 (CAS 9005-65-6): Oleic-acid based, more lipophilic, ideal for oil-rich emulsions in lotions, creams, foods & industrial systems, ensuring long-lasting stability.
💡 Simply put: T20 helps oils blend into water, while T80 keeps high-oil systems stable. Often combined, they allow precise control of oil-to-water balance in formulations.
