All About Clays

At Ibhacares, we love empowering formulators with knowledge about natural raw materials that can transform skincare and haircare creations. Clays have been used in beauty and wellness rituals for centuries – from Cleopatra’s face masks to modern spa treatments. Their ability to cleanse, detoxify, and rejuvenate skin makes them a must-have in any formulator’s toolkit.

What Are Cosmetic Clays?

Clays are naturally occurring mineral-rich substances derived from the earth. Depending on their mineral composition, different clays have varying textures, colours, and benefits. They are highly absorbent, which makes them excellent for:

• Detoxifying and cleansing skin by drawing out impurities

• Absorbing excess oil and sebum• Gently exfoliating dead skin cells

• Delivering trace minerals beneficial for skin health

• Adding natural colour and texture to formulations.

  • Example: French Red Clay gives a warm brick tone, Purple Clay adds a lavender tint, Chocolate Clay creates a rich cocoa brown.

Precautions & Tips for Using Clays

• Some clays (especially Bentonite) expand when mixed with liquids – always use non-metallic bowls and spoons.

• Overuse of strong clays may cause dryness; balance with hydrating ingredients.

• Patch test recommended before use, especially for sensitive skin.

• Do not inhale fine powders – use in a well-ventilated space.

• Keep clays away from water in storage containers to prevent microbial growth.

• Do not let clay packs dry completely on the skin – this can strip too much natural oil and cause dryness.

• Dry roast or lightly heat clays in a microwave before adding to water-based formulations to remove any moisture and prevent mold or fungus.
