Polysorbates

Polyoxyethylene sorbitan esters, also known as polysorbates, are ethoxylated
sorbitan esters. They are non-ionic hydrophilic surfactants that are commonly
used as oil-in-water (O/W) emulsifier.

Our wide product range of ethoxylated sorbitan can be utilized for numerous
applications, including, but not limited to, acting as emulsifiers,
stabilizers, and foaming agents in bread improver and cake oil; stabilize
special emulsification in cosmetics; for polysorbate with high HLB values, they
can be used as solutizers for essence; and for the ones with low HLB values,
they act as emulsifiers for mineral oils. Polysorbates are considered to be
non-toxic and safe food additives when used appropriately. Our polysorbates are
sourced from vegetable/vegan ingredients.

Concocted surfactant mixtures can be made by combining different portions of
polysorbate and sorbitan esters, which can be tailored for specific product
formulations.

Advantages of Huana's Polysorbates

Versatile applications
similar to our sorbitan esters, our polysorbates have multiple functions across
a number of industries. For example, they can be used as emulsifiers in food,
detergent, and industrial formulation; used as a wetting agent, dispersant,
viscosity modifier in cosmetics; and can also be used in the textile auxiliary
agent and veterinary drugs.
Vegetarian & vegan friendly
all of our polysorbates are produced by non-animal sourced ingredients.
Multi-grades
depending on the specifications of our clients, we can produce different grades
of polysorbates, including, food, cosmetic, industrial, pharmaceutical, and
feed grade.
Great solubilizing ability
compare to other existing surfactants, polysorbates can achieve a better
solubilizing effect.
Customizable
products and packaging can be customized according to clients' needs 

FAQs of Our Polysorbates

Is polysorbate safe?
Similar to sorbitan esters, when ingested, polysorbate is hydrated into fatty
acid moiety and polyoxyethylene sorbitan moiety.4 The fatty acids go through
absorption and metabolism, whereas the polyoxyethylene sorbitan portions are
poorly absorbed and excrete the body intact.4 Acute and long-term oral toxicity
studies have shown that polysorbates have a relatively low risk of toxicity.4
The Joint FAO/WHO Expert Committee on Food Additives (JECFA) set a group ADI
value 0-25 mg/kg body weight/day for polysorbate 20, 40, 60, 65 and 80.
Polysorbates are also shown to have no adverse effects, thus they are
considered to be safe food additives. The safety of polysorbates 20, 21, 40,
60, 61, 65, 80, 81, and 85 has been evaluated by The Cosmetic Ingredient Review
(CIR) Panel.5 The panel has concluded that these polysorbates are safe as
cosmetic ingredients.

What is an oil-in-water (O/W) emulsifier?
When an oil-in-water emulsifier is added to a mixture where water is the main
component and oil is minor; it creates an oil-in-water emulsion. The
hydrophobic portions of the emulsifiers surround the oil droplets and
hydrophilic parts interact with the surrounding water environment; this allows
oil droplets to suspend in water.

What is HLB value?
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.

What is the difference between polysorbates and sorbitan esters?
Polysorbates are ethoxylated sorbitan esters that are made by ethoxylation of
sorbitol with different fatty acids. Polysorbates are hydrophilic, whereas
sorbitan esters are lipophilic

What are the differences of the range of polysorbates?
The various polysorbates differ by the type of fatty acids and the number of
fatty acids attached to the polyoxyethylene sorbitan portions of the molecules.
Thus, each of the polysorbates has its own hydrophilicity/lipophilicity
property and characteristic.
Guangdong Huana Chemistry Co., Ltd. is a professional global chemical
