With 370 million pounds per year capacity, it will produce a broad range of nonionic surfactants and specialty alkoxylates, such as kosher polysorbates, amine and alcohol ethoxylates, high molecular weight PEGs and much more.
Based on type the market is stratified as polymers, sugar alcohols, polysorbates, inorganic salts, amino acids, and surfactants amongst others.
Synthetically-derived emulsifiers include polysorbates, currently used in medicines and vaccines with rising debate.
Unfortunately, many use surfactants or "Tweens" including polyethylene glycol, polysorbates, or other ionic detergents as forms of nanotechnology to enhance the absorption of curcuminoids.
Although the demand for nanoemulsions prepared with GRAS ingredients has been increasing, most nanoemulsions are currently formulated with synthetic surfactants such as polysorbates.
Their mild and technically superior features render them extremely attractive for replacing ethoxylated surfactants such as the polysorbates in pharmaceutical formulations, thereby solving the problems of allergies and side-effects associated with the formation of oxidation products including formaldehyde.
The Aegis ProTek excipients provide reduced immunogenicity while avoiding the oxidative damage caused by contaminating peroxides and reactive aldehydes intrinsic to the polysorbates such as Tween-20 and 80, a commonly used polysorbate surfactants found in almost all monoclonal antibody therapeutics.
While the Cognitive-Health category grows in demand, VIRUN have invested in developing water soluble and stable forms of these unique ingredients so they can be used in beverages, foods, supplements and “shots.” Lipids and fatty acids such as Phosphatidylserine and DHA Omega-3 have scientifically supportive health claims yet are nearly impossible to add to beverages and shots as clearer and stable without use of chemical additives (such as EDTA, Polysorbates, or ingredients not approved for direct food use, such as Hydrogenated Castor Oil PEG-40 or Castor Oil, polyoxyethylated).
Polysorbates 80, sodium chloride, carboxymethyl cellulose (CMC), polyvinyl pyrrolidone (PVP), tragacanth, and magnesium aluminum silicate (Veegum) were purchased from Merck, Germany.
