I discovered an article ulprospector highlighting the effect of LGNs in hair conditioners.( said article being https://knowledge.ulprospector.com/8959/pcc-hair-conditioner-formulations/).

In the comment section, someone asked what would be the optimum ratio of low HLB vs high HLB to formulate a daily, economical conditioner. To which the author replied, Typically 1-1.5% Quat (high HLB) and 3-5% Cetearyl alcohol (low HLB) or a ratio of around 25-30%.

Based on the above, what would be the same ratios for:

a daily leave-in conditioner

a detangler

a deep treatment

I'm also struggling with this part under factors affecting LGN performance

" Ratio of high HLB to total surfactant has a significant impact on viscosity and the conditioning properties. For optimum conditioning, this ratio should be ~30%."

Is it possible for someone to elaborate with an example?

## Comments

So 1.5% BTMS and 3.5% fatty alcohol.

Some more questions

All in mol ratio

1. What is the best ratio for maximum emulsion stability?

2. What is the best ratio for maximum conditioning in hair conditioner?

3. Can liquid emulsifier like polyglyceryl-4 laurate+ GMS or fatty alcohol make LGN products?

4. Can SLS or SLES+ GMS or fatty alcohol make LGN product?

5. If GMS is used as LGN promotor, what should be counted as it's molecular weight?

For example

GMS is 358.57g/mol(google search

So if i am using GMS with 40% mono, should i count it as 500.512 g/mol or 358.57 g/mol?

@Pharma if I were to design an experiment to determine which mole ratios would work with the various surfactants and 'LGN promoters' that I have, how would I go about it?
