How do you calculate HLB value of cream?
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.
What is the HLB of emulsifier?
HLB is an index of the solubilizing properties of emulsifiers and indicates the type of emulsion (o/w or w/o) that the emulsifier is best suited for (Table 2). HLB values can be calculated based on the molecular structure of the emulsifier or determined empirically.
What does HLB mean in cosmetics?
hydrophilic-lipophilic balance
HLB is short for hydrophilic-lipophilic balance. Created by William C. Griffin in the late 1940s, the HLB System is one of the most successful strategies for developing stable emulsions.
What is the HLB value of oleic acid?
1
Oleic acid HLB value is 1, While RHLB is 17 for oil in water emulsion?
Why is HLB SLS 40?
Since SLS is more soluble in water than the oil, water is the continuous phase while the oil is the internal phase. In addition, SLS has a very high HLB value of 40 meaning it is water soluble and it prefers to form o/w emulsions.
What is the HLB value of detergent?
The calculated HLB values from both methods can be used to predict the surfactant properties of a surfactant molecule, where a value from 1 to 3 indicates a antifoaming agent; a value from 3 to 6 indicates a W/O emulsifier; a value from 7 to 9 indicates a wetting agent; a value from 8 to 12 indicates an O/W emulsifier; …
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.
What is the HLB value of mineral oil?
4
For example, mineral oil has an HLB value of 4 if a w/o emulsion is desired and a value of 10.5 if an o/w emulsion is to be prepared. Therefore, to prepare a stable emulsion the EA should have an HLB value similar to the one of mineral oil depending on the type of emulsion required.
