Novel Behavior of Heat of Micellization of Pluronics F68 and F88 in Aqueous Solutions

Langmuir, 2008
It is well understood that the heat of micellization for surfactants is monotonically decreased along with an increase in temperature. However, this behavior for polymeric surfactants has never been carefully examined. In this study, the heat of micellization of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) triblock ...

Carboxymethyl cellulose and Pluronic F68 protect the dinoflagellate Protoceratium reticulatum against shear-associated damage

Bioprocess and Biosystems Engineering, 2010
The red-tide dinoflagellate Protoceratium reticulatum is shown to be protected against turbulence-associated damage by the use of the additives Pluronic F68 (PF68) and carboxymethyl cellulose (CMC) in the culture medium. Relative to agitated controls, these additives had a dose-dependent protective effect at concentrations of up to 0.4 and 0.5 g L(-1 ...

Relating emulsion stability to interfacial properties for pharmaceutical emulsions stabilized by Pluronic F68 surfactant

International Journal of Pharmaceutics, 2017
We explore mechanisms of emulsion stability for several systems using Pluronic F68 and a range of oils commonly used in pharmaceutics and cosmetics. We report measurements of dynamic emulsion drop size, zeta potential, and creaming time, as well as dynamic interfacial tension and interfacial viscoelasticity. Experiments show that with 1wt% Pluronic F68,

Suppressor Effects of Sodium Pentaborate Pentahydrate and Pluronic F68 on Adipogenic Differentiation and Fat Accumulation

Biological Trace Element Research, 2019
Obesity is a major public health problem worldwide and a risk factor for certain diseases, including cardiovascular disease, diabetes, cancer, and depression. Unfortunately, currently available anti-obesity drugs have failed in the long-term maintenance of weight control.

Evaluating the impact of high Pluronic^® F68 concentrations on antibody producing CHO cell lines

Biotechnology and Bioengineering, 2014
ABSTRACTPluronic® F68 (P‐F68) is an important component of chemically‐defined cell culture medium because it protects cells from hydrodynamic and bubble‐induced shear in the bioreactor. While P‐F68 is typically used in cell culture medium at a concentration of 1 g/L (0.1%), higher concentrations can offer additional shear protection and have also been ...

Small-angle neutron scattering study of Pluronic F68 tri-block copolymer solutions

Physica B: Condensed Matter, 1997
Abstract Concentration and temperature dependence of the structure of Pluronic F68 tri-block copolymer in heavy water solutions is investigated in the concentration range 5–100 g/dm 3 at 20, 40 and 60°C. At 20°C the chains form random coils. At 40°C and at concentrations higher than 10 g/dm 3 , part of the molecules are in aggregated form but the ...
