  • Allantoin and Urea….and advantage of increasing Allantoin…if any?

    Posted by Graillotion on February 13, 2023 at 6:12 pm

    A rainy day in the rain forest, so trying a new hack…of reading every comment @chemicalmatt has ever made…on any topic….YUP….44 pages! 🙂

    So I came across several times (in Matt’s comments)….Urea enhances the ability of allantoin to go into solution. So, I use the standard formula…of using .5% of the water phase as my allantoin inclusion rate. This leads me to two questions.

    1) Is there any research that would indicates there is a benefit of allantoin at higher rates than what I am using?

    2) I do not use the form of Urea that I am sure Matt was referencing. However I do use Hydroxyethyl Urea (aka: Hydrovance). Will this also increase the amount of allantoin that will go in to solution?

    Bonus question: 3) I had also heard (I think….might be confusing this with Salicylic acid ) that betaine also helps in this regard. Is this correct…and if so, what would be the most effective? I use betaine in all formulas, and use Hydrovance in very limited number of formulas.

    Aloha.

    Found a mention about Betaine for Allantoin previous when searching for Salicylic Acid.

      Wow… 20X more allantoin with betaine.

      Guess the real question is….where is the sweet spot with Allantoin?

      Thank you….One always hopes they are not losing their mind. 🙂

    I don’t think it is 20x more allantoin,

    Without betaine it is 0.5%

    With 50% betaine it is 1.4%
