Key Features

Oral
•A non-ionic water dispersible surfactant composed of well-characterised polyethylene glycol (PEG) esters, a small glyceride fraction and free PEG.

 

•Able to self-emulsify on contact with aqueous media forming a fine dispersion ie. microemulsion (SMEDDS).


•Solubilizer and wetting agent: Surfactive power improves the solubility and wettability of active pharmaceutical ingredients in vitro and in vivo.

 

Topical
•An oil-in-water surfactant used to solubilize active pharmaceutical ingredients and promote drug penetration and permeation.


Safety of use is supported by extensive toxicological evaluations and precedence of use in approved pharmaceutical products.
