INGREDIENT 101: Australian White Clay
Achieve Clear Skin With Australian White Clay
The Use of Clay Goes a Long Way Back
Clay (kaolin) has been used for centuries to heal wounds, soothe irritations and to clean the skin. About 5,000 years ago, clay was listed in the ancient tablets of Nippur (an ancient city in Iraq) as a wound healing remedy. Clay was also used to treat conditions such as diarrhoea, tapeworm and wounds based on the Ebers Papyrus (a medical document from ancient Egypt).
What is Clay?
Clay is a fine-grained natural mineral that has plastic properties with the appropriate water content (think plasticine) and hardens when dried or fired. They form in soils and sediments as a result of the alteration of rocks during weathering.
Clay has negatively charged surfaces that attract positively charged particles such as grime, impurities and dirt. Certain clay minerals absorb these particles between the layers of their crystal structure. This property allows the absorption of impurities and clogged oil from your skin.
However, interestingly, kaolin clay does not have strong absorbing abilities (which is why it's great for sensitive skin!) but strong adsorbent properties. This means that substances such as grime and dirt are attracted to the clay and bind to its outer surface rather than the clay absorbing these substances like a sponge.
Different Types of Clay
Our Rose Masquerade Purifying Clay Mask contains Australian white clay which is a fine and soft powder that is gentle and smooth on the skin. It is the gentlest of all clay making it ideal for all skin types, especially sensitive skin.
Here are some of the different kaolin types:
- Bentonite clay (Montmorillonite): It is a sedimentary clay made from weathered and aged volcanic ash. It is commonly used to modify the viscosity in cosmetics and has various benefits when applied topically or when ingested.
- White clay: It is rich in silicon and aluminium silicate. It provides mild exfoliation and is not overly drying for the skin hence, suitable for all skin types.
- Red clay: The presence of iron oxide gives its red appearances and more absorbing properties hence, suitable for oily skin types.
- Pink clay: It is a mix of white and red clay. Due to its high kaolin content, it is safe for sensitive, dry or oily-combination skin types.
- Green illite clay (also known as French green clay): The presence of iron oxides and decomposed plant matter contributes to its green colour. It is suitable for oily skin types due to its strong oil-absorbing properties.
