TWEEN 80 is a polyethylene sorbitol ester, with a calculated molecular weight of 1,310 daltons, assuming 20 ethylene oxide units, 1 sorbitol, and 1 oleic acid as the primary fatty acid.4 Fatty acid constituents of this product are determined by transesterification to yield fatty acid methyl esters, Analysis of Tween 80 by high- performance liquid ... Tween 80 is commonly used as a stabilizing excipient in pharmaceutical medications, or an anticalcification agent for tissues treatment. The quantification of Tween 80 is challenging because of the heterogeneous mixtures and lack of good chromophore. This study developed a simple and fast high-performance liquid Tween 80 - an overview | ScienceDirect Topics Tween Hydrolysis Test. The test medium contains tween 80 and the indicator is neutral red in a buffered neutral solution. Normally, neutral red is red at PH = 7.0, but when bound by lipids or by tween 80, the indicator dye takes on the amber or straw color which ultimately occurred at alkaline PH.

Tween 80 is a nonionic surfactant that usually used in pharmaceutical products. The effect of Tween 80 on the penetration of ascorbic acid through rabbit skin has been investigated and reported that the higher. Hakim Bangun et al /Int.J.PharmTech Res.2013,5(3) 966

DELAYED EFFECTS OF NEONATAL EXPOSURE TO TWEEN 80 … Tween 80, in two rats the uterus was enlarged and had a marked vascular pattern. Increased relative weight of the adrenals was found in all groups, in comparison with the untreated control, although only in the 1% Tween 80 group was the increase statistically significant (P ~< 0.05).
