Uses & Benefits

Rhassoul is a naturally occurring magnesium-rich clay mined from the Jbel Ghassoul deposit in Morocco. Its principal clay mineral is stevensite, accompanied by naturally varying amounts of quartz, dolomite, and other minerals. Its high surface area and adsorption capacity allow it to bind oils, debris, and dissolved substances, making it especially valuable for gentle cleansing masks, powdered facial cleansers, scalp treatments, and mineral-rich hair care.

Oil Absorption & Gentle Cleansing

• Absorbs excess surface oil and helps lift away dirt, residue, and environmental debris.

• Cleans without relying on soap or synthetic surfactants, making it useful in water-activated powdered formulas.

• Can leave oily or combination skin feeling cleaner and more balanced without the intensely drying feel of some stronger clays.

• Its cleansing action is physical and adsorptive; it does not “pull toxins” from inside the body.

Skin Softness & Smoother Texture

• Fine mineral particles help loosen surface buildup when gently massaged and rinsed away.

• Leaves skin feeling smoother, softer, and freshly polished after rinse-off use.

• Can improve the sensory feel of powdered cleansers and masks by adding slip, creaminess, and body when hydrated.

• Excessive rubbing or allowing the clay to dry completely may irritate sensitive or compromised skin.

Pore & Blemish-Prone Skin Support

• Helps reduce the visible shine and surface congestion associated with excess oil.

• May make pores appear temporarily cleaner and less noticeable by removing accumulated oil and debris.

• Useful in rinse-off formulas intended for oily, congested, or blemish-prone skin.

• Rhassoul does not medically treat acne, infection, inflammation, or enlarged pores.

Scalp Cleansing & Hair Care

• Absorbs excess scalp oil, styling-product residue, and surface impurities.

• Traditionally used as a mineral hair wash that cleanses without conventional shampoo surfactants.

• Adds body and texture to fine or oily hair by removing excess coating from the hair shaft.

• May leave hair feeling soft and manageable when thoroughly rinsed, although frequent use may be drying for very porous, damaged, curly, or coarse hair.

Formula Texture & Absorbency

• Functions as an absorbent, bulking agent, opacifier, and natural texturizer in dry cosmetic formulas.

• Swells and forms a smooth paste when mixed with water, hydrosol, or another suitable liquid.

• Can help reduce greasiness in oil-rich masks or cleansing pastes.

• Mineral composition, swelling behavior, color, and texture can vary by deposit and processing method.

Formulation & Safety Considerations

• Use finely milled, cosmetic-grade clay that has been tested for microbial quality and potentially harmful metals.

• Natural clays may contain trace metals and mineral contaminants; “natural” does not eliminate the need for supplier testing.

• Avoid breathing airborne powder. Wear appropriate respiratory protection during larger-scale weighing and blending.

• Do not apply to broken, severely irritated, or actively inflamed skin.

• Patch-test finished formulas, especially when combined with essential oils, acids, or highly active botanicals.

• Discard clay once it has been mixed with water unless the finished product contains a suitable preservation system.
