Adding Allantoin and Natural Betaine to Your Lotion

Yes, you can generally use the recommended usage percentages for Allantoin and Natural Betaine when adding them to your homemade lotion. However, it's always best to check the specific product page for each ingredient you purchased to confirm the recommended usage rate and any specific instructions from the supplier.

Both Allantoin and Natural Betaine are water-soluble powders. Therefore, the correct step to add them to your lotion is to dissolve them in the water phase of your formula before you combine the water and oil phases for emulsification.

Here's the recommended process:

1. Prepare your water phase ingredients.
2. Weigh out the calculated amounts of Allantoin and Natural Betaine based on your total lotion batch size and the recommended usage percentages.
3. Add the Allantoin and Natural Betaine powders to your water phase.
4. Mix or blend the water phase thoroughly until both powders are completely dissolved. Natural Betaine actually helps improve the solubility of Allantoin in water, which is beneficial.
5. Proceed with heating and combining your water and oil phases according to your lotion recipe to create the emulsion.

Adding these ingredients during the cool-down phase with preservatives is not recommended because they need to be fully dissolved in the water phase to be evenly distributed and effective in the final product.

Allantoin is typically used at a concentration of 0.1-2.0% (note that its solubility in water at room temperature is around 0.5%). Natural Betaine is commonly used at 2-10%. Both are excellent ingredients for sensitive skin, known for their soothing, hydrating, and anti-irritant properties.
