Determining Shelf Life of Scrub Based on Ingredient Expiry Dates

Regarding your question about determining the shelf life of your scrub formula by looking at the expiry dates of the raw materials, yes, for these specific formulas containing sugar, cocoa/coffee grounds, and fractionated coconut oil, you can estimate the shelf life of the final scrub based on the earliest expiry date among the individual ingredients.

This approach is valid because the ingredients in these formulas do not undergo significant chemical reactions with each other that would cause the mixture to degrade faster than the individual components. Therefore, the component with the shortest shelf life will generally dictate the overall shelf life of the finished product.
