Alkanolamides, an non ionic surfact are widely used in manufacturing of detergents and cosmetics.

Can anyone please explain to me which properties of the alkanolamides determines the viscosity, foaming and detergency?

I would like to use Cocamide Diethanolamide (CDE) as an example, which is synthesis using fatty acids/triglyceride and diethanolamine. However, how should one increase or even decrease on the viscosity, foaming or detergency of this surfactant if required??

So far what i read up on but am unsure if i am right here.

- better solubility equates to poorer viscosity?

- better solubility equates to better foaming features?

- Is detergency determined by any of these 2 factors?

Is there a simple chemistry explanation to the points above for a layman? Thanks.
