• Aluminum oxide (Al₂O₃, approximately 17%) contributes to the cation exchange capacity of clay.

• Iron oxide (Fe₂O₃, approximately 5.8%)

• Potassium oxide (K₂O, approximately 3.1%), magnesium oxide (approximately 2.1%) and calcium oxide (approximately 4.7%)

The use of black clay in cosmetics

Skin care: Best for oily, combination or problematic skin. For dry or sensitive skin, limit use to once a week.

To make a mask, mix 1 part clay with 1.5 parts liquid (spring water, flower water, or herbal tea). Apply a thick layer to the skin, avoiding the eyes and lips, leave on for about 10 minutes, then rinse and moisturize.

Hair care Suitable for all hair types, best for dark hair.

• Scalp mask: apply to damp scalp, leave on for about 10 minutes, then rinse.

Soap making

• Cold process soap: To avoid lumps, mix clay powder in water or vegetable oil in a ratio of 1:3. Use up to 5 g per 450 g of soap fats. You can mix the clay with the fats before mixing with the soapstone solution or into the finished soap mixture before pouring into the mold.

• In ready-made soap mass, use ¼–½ teaspoon per 500 g of soap mass.

Not recommended for use: Daily use may be drying for dry or very sensitive skin. Pigment may tint hair on light hair.

Interaction with other substances. Clay is a natural mineral mixture that is stable in acidic, neutral and alkaline mixtures. It is insoluble in water or oil, and in liquid products it settles to the bottom over time.

When making clay products, use glass, ceramic, or wooden utensils, avoid using metal utensils. It is recommended to use spring or filtered water as the liquid, not tap water.
