Sorbitan Esters & Polysorbates

 Sorbitan esters and Polysorbates as nonionics offer many advantages over ionic surfactants including increase stability, enhance flexibility and provide wider compatibility. They are stable in mild acids, alkalis and electrolytes and do not react with ionic ingredients or actives. They are used as emulsifiers, foamers, defoamers, dispersants, lubricants, solubilizers, stabilizers, viscosifiers, diluents, wetting agents etc.

Sorbitan Esters

Sorbitan esters are nonionic surfactants that can be mixed with polysorbates in varying proportions to produce emulsions with a variety of textures and consistencies. They can dissolve in a variety of organic solvents as well as hot oil to create water in oil (W/O) emulsions. They are non-toxic and biodegradable, which can be used in foods, pharmaceuticals, cosmetics, textiles industry, and so on.

Polysorbates

Polysorbates (also known as Ethoxylated Sorbitan Esters) are formed by condensation of residual hydroxyl groups in sorbitan ester molecules with ethylene oxide. During the process of polyoxyethylene, transesterification occurs, and the ester groups formerly directly attached to sorbitan can be rearranged to the hydroxyl terminus of the oxyethylene chain. They are suitable for use as oil in water (O/W) emulsifiers, solvents, dispersants, stabilizers, antistatic agents, lubricants, and detergents.

What is HLB value?

图片
  WHAT IS HLB ? HLB value is the abbreviation for hydrophilic-lipophilic balance, it is the ratio between the hydrophilic portions and lipophilic portion of a surfactant. It is represented by a number between 1 and 20. An HLB value less than 6 indicates that the surfactant favors W/O emulsion; an HLB value greater than 8 favors O/W emulsion. HLB values in between 7 and 9 indicate that the surfactants are good wetting agents. Huana  has been professionally concentrated on Sorbitan  Esters & Polysorbates since 1993, with decades of R&D and production experience.

Differences between polysorbate 20 and polysorbate 80

图片
  W hat I s the D ifference between polysorbate 20 and 80   Synthetic Raw Materials Difference between  P olysorbate 20 80 Polysorbate 20 is a product of the polymerization reaction of sorbitan monolaurate and ethylene oxide, while polysorbate 80 is synthesized by the polymerization of sorbitan monooleate and ethylene oxide.   Application Difference between Polysorbate 20 and 80 P olysorbate 20 uses in cosmetics   is known as a non-ionic stain remover because it has relatively more hydrophilic groups (polyoxyethylene), which gives it a strong hydrophilicity property. Polysorbate 20 is usually used as an oil-in-water(O/W) type emulsifier and solubilizer.   Polysorbate 80 is one of the most common polysorbates. The   polysorbate 80 emulsifier   has significant resistance to electrolyte and strong hydrophilicity, which allow it to be widely used in liquid, semisolid and solid preparations. Polysorbate 80 is used as an oil-in-water(O/W) type emulsifie...
