What is Walnut Shell?

Walnut shells are the hard, outer coverings of walnuts. They are typically collected during the walnut processing phase where the nut is extracted for culinary use. The shells are ground into a fine powder for various applications.

Walnut shells are commonly used in cosmetic and personal care products, such as exfoliating scrubs, and in industrial applications like abrasives for cleaning and polishing. There is no significant health evidence regarding safety concerns, though those with walnut allergies should exercise caution.

When listed on labels, walnut shell ingredients are often included for their texture and abrasive properties rather than nutritional benefits or direct health effects.
