The HLB values of surfactants
Hi everyone,
I’ve been searching to find the HLB values of surfactants but the more I search the less I find. I need the values of- Sodium Cocoyl Isethionate - Sodium
Lauroamphoacetate- Caprylic, Capric
Glucoside- Cocamidopropyl
betaine- Sodium
Lauroyl Methyl Isothionate- Lauryl
Glucoside
Does anyone hear know where I can find them. I really appreciate your help in advance. -

Glucosides are between 10-15.
Others are above 15

As a rule of thumbs, traditional anionic surfactants often have HLB values above 15 (sulfates even above 20 and di-anionic ones above 25).However, using a modified method according to Davies, I came up with ~7 for sodium cocoyl isethionate and sodium lauroyl methyl isethionate (which is obviously utter nonsense) and ~13 for caprylic/capric and lauryl glucosides. However, calculated HLB refer to pure compounds and may deviate considerably from measured values of cosmetic grades. Also, HLB is often not applicable to non-traditional (PEG-based and SLS derivatives) emulsifiers.
