Green French Clay

Green French Clay is a mineral-rich natural clay composed mainly of:

Illite
Montmorillonite
Kaolin
Iron oxides (give the green colour)

It’s one of the strongest absorbing and purifying clays in cosmetics.

Key Cosmetic Benefits

   Helps unclog pores and reduce congestion.
   Regularly used in acne-prone and oily-skin formulations.

2. Exfoliation and Skin Renewal
   Provides very gentle physical exfoliation.
   Improves texture and smoothness.

3. Improves Skin Tone
   Iron oxides and minerals can brighten dull skin.
   Helps reduce the appearance of minor blemishes.

4. Soothing and Mineral-Rich
   Contains magnesium, calcium, potassium, and silica.
   Helps soothe irritated or inflamed skin, especially when mixed with hydrating agents.

Solubility and How to Use

Not soluble in water or oils
Must be mixed into water phase
Avoid using metal spoons or bowls as they can react with minerals
Hydrate clay slowly into warm water for smooth texture
Can be added at cool-down in emulsions to avoid clumping

Formulation Tips

1. Avoid high pH
   Clay raises pH slightly; adjust with citric acid if making a balanced cleanser or mask. Recommended pH is around 5.

2. Add humectants
   Clay alone can feel drying. Combine with glycerin, honey, aloe vera, propanediol, or panthenol.

3. Add soothing ingredients
   To reduce irritation, add allantoin, oat extract, chamomile extract, panthenol, or centella asiatica.

4. Preserve water-based clay formulas
   If your clay mask contains water, you must use a preservative.

Safety and Precautions

Very strong oil absorber, may be drying on sensitive or dry skin
Use lower percentages (5–15%) for mild or daily cleansers
Avoid allowing the mask to fully dry; mist with water if needed
Not recommended daily, ideal use is 1–3 times per week
