Carbamide VS Hydroxyethyl urea

What are the key differences between the two in terms of:

1. Function or performance 
2. Formulation 

I know that carbamide comes as a lose powder and is comparatively more challenging to work with. HEU, on the other hand, is supplied as a 50% aqueous solution and can be readily added to a formula.

  • If based on basic information on paper: 
    Besides from Urea normally being a solid and Hydroxyethyl Urea in liquid form, both can have their challenges since they can cause a drift in pH. This would be stated in the Hydrovance (Hydroxyethyl Urea) product brochure or TDS. That would probably be the main challenge if at all. 

    If based on experience and observation:
    Urea exfoliates me. For Hydroxyethyl Urea, based on the toner i made for my aunt, she hasn't feedback anything regarding the issue for exfoliation. I haven't tried it on myself at the moment.

    Thank you for your response! What % have you been using them at? 
  • 5% Urea for the body & 3% Hydroxyethyl Urea (solids)
