What is the HLB of glyceryl stearate?

It is an emulsifier with a HLB value of 5.8 and thus useful for making water-in-oil emulsions.

What is the HLB of polysorbate 80?

Polysorbate 80 has an HLB value of 15, so it works best in oil-in-water emulsions, such as mayonnaise. Try using an amount that is 5% of the volume of the oil phase.

What is the HLB of cetyl alcohol?

Each ingredient has a specifically required HLB in order for it to be emulsified. Cetyl alcohol for example requires an HLB of 15.5 whereas hemp seed oil requires an HLB of 7 to be emulsified in water.

What is the HLB value of Steareth 21?

HLB Values for Surfactant

How is HLB calculated?

HLB= E / 5 can be calculated with this equation. E: Percentage by weight of ethyleneoxide • HLB value of fatty acid esters of polyhydric alcohols such as glyceryl monostearate, HLB= 20 [1-(S / A)] is calculated with that equation. The HLB values of some of the most frequently used surfactants are shown in Table 11.1.

Is Glyceryl Stearate bad for skin?

Glyceryl Stearate acts as a lubricant on the skin’s surface, which gives the skin a soft and smooth appearance. The Food and Drug Administration (FDA) includes Glyceryl Stearate (also called glyceryl monostearate) in its list of direct food additives affirmed as Generally Recognized As Safe (GRAS ).

What is Span 80 used for?

Span 80 is a liquid W/O emulsifier and O/W emulsion stabiliser particularly recommended for use with unsaturated lipid components such as oleyl alcohol or vegetable oils. Extensively used as a wetting agent and dispersant for materials such as zinc oxide, calamine and penicillin in lipophilic pharmaceutical bases.

Is cetyl an alcohol?

Cetyl alcohol is a fatty alcohol that functions as an emollient, emulsifier, thickener, and surfactant in a variety of cosmetics and skincare products. Cetyl alcohol is an organic compound that is classified as a fatty alcohol. Fatty alcohols are a hybrid between alcohols and fatty acids or oils.

What is the HLB value?

Hydrophilic–lipophilic balance (HLB) is the balance of the size and strength of the hydrophilic and lipophilic moieties of a surfactant molecule. The HLB scale ranges from 0 to 20. Surfactants with HLB values in the 8 to 18 range are most commonly used in O/W emulsions (Griffin, 1949).

How HLB values are assigned?

The hydrophilic-lipophilic balance (HLB), often used to describe surfactants, is calculated from the weight percentage of the hydrophilic groups to the hydrophobic groups in a molecule, with values ranging from 1–20 (Kralova and Sjöblom, 2009). Surfactants with HLB values between 8–16 tend to form o/w emulsions.

What is the HLB value of detergent?

The HLB (hydrophilic/lipophilic/balance) number of a detergent is an empirical measure of its relative hydrophobicity. Detergent HLB numbers vary systematically with the length of the ethylene oxide chain for a homologous series of detergents such as the Triton X series.

Is glyceryl stearate good for face?

Its Glycerol component makes Glyceryl Stearate SE a fast-penetrating emollient when applied topically, which helps to create a protective barrier on the skin surface. Its protective characteristics extend to its antioxidant properties, which help protect the skin against free radical damage.

What is the HLB value of glyceryl stearate SE?

Glyceryl stearate SE is an emulsifier with a HLB value of 5.8. HLB (Hydrophile-Lipophile Balance) is an empirical expression for the relationship of the hydrophilic (“water-loving”) and hydrophobic (“water-hating”) groups of a surfactant. An HLB of less than 10 means that the substance is soluble in oil.

What can glyceryl stearate SE be used for?

Glyceryl stearate is also a food additive that is primarily used in baking preparations. You may also see “glyceryl stearate SE” on product labels. Glyceryl stearate SE is a “Self-Emulsifying” form of glyceryl stearate that also contains a small amount of sodium and/or potassium stearate.

What kind of emollient is glyceryl diester made of?

Description: Glyceryl diester made of glycerin and fatty acids derived from vegetable oils. Acts as hydrophilic, PEG-free, anionic o/w emulsifier and emollient. Well suited for emulsions with a slightly acidic pH-value or emulsions with UV filters. HLB value 12. Oil-soluble, only partly water soluble.

What is the saponification index of glycerol monostearate?

For glycerol monostearate (1 stearyl for 1 glycerol), the HLB would be 4.2, given that the saponification index is 154.4 and the acid index is 197.1. Thus, this molecule is hydrophobic, and can be used to stabilize an emulsion of water in oil. When the saponification index is difficult to obtain, there is another relation which can be used:
