The HLB value calculated for the mixture of tween20/ propylene glycol was in a range between 10.1 and 13.4.

What is the HLB of glycerol?

insoluble in water (Burdock, 1997). The hydrophilic-lipophilic balance (HLB) of glycerol monooleate is 3.8 (Griffin, 1979). 60.

Is propylene glycol an emulsifier?

Propylene glycol fatty acid esters are lipophilic, oil-soluble emulsifiers with specific crystalline properties. … The use of propylene glycol esters of fatty acids in foods, as with all other food emulsifiers, is controlled by health authorities.

What is the HLB value of Tween 20?

16.7 With this in mind, when you see that an ICI emulsifier such as TWEEN 20 polyoxyethylene (20) sorbitan monolaurate has an HLB value of 16.7, you know that it is about 84% hydrophilic.

What is the HLB value of Tween 80?

15 Tween 80 has an HLB value of 15, within the range of HLB 8–18 for oil-in-water (O/W) emulsifiers.

What is HLB value of Acacia?

11.87 The hydrophile-lipophile balance (HLB) of acacia has been determined in the presence of various ethylene oxide derivatives of sorbitan fatty acid esters. It was also found that different lots of acacia produced the same HLB values. A revised HLB value of 11.87 for acacia has been proposed.

How do you calculate HLB value?

Using the following equation: HLB desired = ( % surfactant A ) × ( HLB Surfactant A ) + ( % surfactant B ) × ( HLB Surfactant B . ) A blend of surfactant A, HLB = 7.8, and surfactant B, HLB = 13.4 produces a combination that is water soluble and contributes other desired properties.

What is propylene glycol in?

Propylene glycol is commonly found in many packaged foods, such as drink mixes, dressings, dried soups, cake mix, soft drinks, popcorn, food coloring, fast foods, bread and dairy products ( 6 ). … Additionally, it is used in industrial products like paint, antifreeze, artificial smoke and e-cigarettes (2, 6 ).
