The amount of arrowroot powder to use in a body butter recipe can vary depending on the desired consistency and texture. Arrowroot powder is often used as a natural thickening agent in skincare products, including body butters, as it can help to absorb excess oil and provide a silky smooth feel to the product.

A general guideline is to use around 1-2 tablespoons of arrowroot powder per cup of body butter mixture. However, it's important to note that this can be adjusted based on personal preference and the specific recipe you are using.

It's recommended to start with a smaller amount, such as 1 tablespoon, and gradually add more if needed. Mix the arrowroot powder with the other ingredients in the body butter recipe, ensuring that it is well incorporated before adding any additional amount.

Remember to test the consistency and texture of the body butter as you go, as too much arrowroot powder can make the product feel overly thick or powdery on the skin. Adjust the amount according to your desired consistency and personal preference.
