Leave In vs rinse out conditioner?
I am wondering what you consider the major differences when it comes to formulation between a leave in & rinse out conditioner?

The primary differences are these…
1. Leave-in - Contains a high level of humectants, very low level (or none) quats. Lower level of most ingredients as you don’t need as much since it doesn’t get rinsed away.2. Rinse-off - Contains a high level of Quats. Not as much humectants since they aren’t really effective from a rinse off. Higher level of silicone also.Perry, 44 -
I would focus the difference on the amount of cationic emulsifiers and humectants because some hair types require high amounts of oil content and silicone, etc.

Would an AHA peel be considered a rinse off or a leave on?

@ChemWizard,
I guess AHA peel is definitely supposed to be a rinse off product unless you include no more then 1-1,5% of AHAs in your formulation. For instance: you may want to put Citric acid, Lactic acid and Glycolic acid…
AHA are almost all excellent Keratolytics, so if they used as a leave on product - the hair is getting weak, thin and fragile. -

@pe@Perry how much humectant like glycerin would you recommend for leave in conditioner?
What is the benefit of humectants for hair?
