Know Your Ingredients: Allantoin


What it is
Allantoin is a white powder. It can be found in plants, like comfrey and horse chestnut, and in the urine of most mammals. The type that is most commonly used in cosmetics and skincare products though derives from urea and glyoxylic acid.

What it does
Allantoin has anti-irritant, soothing and healing properties: it calms down irritations, helps shed the upper layers of dead skin cells and promotes the growth of healthy tissue. That’s why it’s effective at treating wounds,eczema, psoriasis, burns and other skin conditions.

Side effects
Allaintoin, used in concentrations ranging from 0.5% to 2%, is considered safe.

      Kanwal, allantoin can be derived from the comfrey plant although some companies find it cheaper to produce it in a lab by mixing urea and glyoxylic acid. Urea too can be derived from urine of mammals or made in a laboratory as well. Thing is, there are lots of ingredients that can be either derived naturally or produced synthetically and while organic brands generally use the first type (derived from plants), there is no way of knowing what other companies use as they don’t have to share this information with the consumers.

    It would be really helpful to note the annunciation of these ingredients. And it would be extra nice to know the PH of these ingredients as well. You have done such a nice job with descriptions. I like your handle beautifulwithbrains!

    Thank you,

      Jane, thank you for your kind words and your suggestions. A lot of ingredients are used in formulations at a ph that matches that of our skin, but some need a higher or lower ph than normal, and when they do, I’ll add that information to the post in the future. :)

    I am inquiring of another ingredient that is listed in the first 5 ingredients of my shampoo and currently not on your list. It is Behentrimonium Methosulfate. Would you add it to your listing?

    Thank you again,
