Kaolin Clay
What Is It?
Kaolin clay is a gentle, natural mineral clay composed primarily of kaolinite. It is widely used in skincare for its absorbent, purifying, and soothing properties. Ideal for sensitive skin, kaolin clay helps to detoxify the skin, control excess oil, and gently exfoliate without causing irritation. It is a key ingredient in facial masks, cleansers, and dry shampoos.

Kaolin
Proper Storage & Shelf Life
Store in a cool, dry place, away from moisture and direct sunlight. Keep in an airtight container to prevent contamination. Indefinite when stored properly, as it is a mineral and does not expire.
Refined Or Unrefined
Refined Kaolin Clay is purified to remove impurities, resulting in a smoother texture and a bright white colour. This type is commonly used in cosmetics, skincare, and pharmaceutical products.
Unrefined Kaolin Clay is more natural, containing trace minerals and slight colour variations (white, pink, yellow, or grey). It is often used in DIY skincare, soap-making, and pottery.
Is It Necessary?
Not essential, but highly beneficial for detoxifying, oil control, and gentle exfoliation. Perfect for face masks, dry shampoos, and cleansing recipes.

PH
Kaolin clay has a pH range of approximately 4.0 to 5.0, making it slightly acidic. However, depending on its mineral composition and source, the pH can sometimes vary up to 6.0.
Absorbency Rate
Kaolin clay has a moderate oil and water absorbency compared to other clays. It is less absorbent than bentonite clay but still effective at drawing out excess oil and impurities. Its absorbency rate depends on the particle size and composition, but it generally absorbs about 65-75% of its weight in water.
