Tween Series - PC
The TWEEN Series of surfactants are polyoxyethylene derivatives of the SPAN™ Series products. TWEEN surfactants are hydrophilic, generally soluble or dispersible in water, and soluble in varying degrees in organic liquids. The TWEEN Series are excellent O/W emulsifiers, solubilizers, wetting agents and dispersants. In emulsion systems they are commonly used in combination with the corresponding SPAN. Manipulation of the SPAN/TWEEN ratio produces emulsifying systems of various HLB (hydrophilic-lipophilic balance) values, allowing the emulsification of many cosmetic ingredients.
