The scene centers on a light-washed cedar stool positioned beside a white porcelain sink, creating an intimate, everyday skincare moment that feels both nurturing and relatable. Three handmade kaolin clay soap bars, each tailored to a different skin type, rest atop kraft paper sleeves with handwritten labels: • Left: A creamy ivory bar labeled “For Dry Skin” in gentle cursive, crowned with a single dried chamomile flower and a faint dusting of oat flecks. • Center: A soft lavender bar labeled “For Sensitive Skin”, its surface smooth and calming, topped with a tiny sprig of dried lavender. • Right: A pale mint-green bar labeled “For Oily Skin”, lightly textured with a subtle swirl and a few crushed rosemary leaves for balance.

As an experienced artisan soap maker, I’ve worked with countless natural ingredients over the years, but one that stands out for its versatility and gentle nature is kaolin clay. Known as "white clay," this mineral-rich ingredient has been a favourite amongst soap makers and skincare enthusiasts alike for its ability to cleanse without stripping the skin. Whether you have dry, oily, or sensitive skin, kaolin clay soap offers a gentle yet effective solution for daily cleansing.


What Is Kaolin Clay?


Kaolin clay, named after the Kaoling mountain in China where it was first discovered, is a naturally occurring clay mineral composed primarily of kaolinite. Its fine texture and mild cleansing properties make it ideal for skincare applications. Unlike harsher clays, kaolin is incredibly gentle, making it suitable for all skin types, from sensitive to mature skin.


In soap making, kaolin clay is often added to enhance the cleansing experience, improve lather quality, and provide a silky texture to the finished bar. Its absorbing properties help to remove impurities while leaving the skin soft and refreshed.


Why Choose Kaolin Clay Soap?


  • Gentle Cleansing: Kaolin clay is mild enough for everyday use, making it perfect for delicate facial skin and even those with sensitive or dry skin.

  • Oil Absorption: While gentle, kaolin clay can absorb excess oil, making it useful for balancing oily or combination skin.

  • Improved Texture: In handmade soaps, kaolin clay adds a smooth, luxurious feel to the lather.

  • Natural and Sustainable: As a naturally sourced ingredient, kaolin clay aligns with eco-conscious values.


How Kaolin Clay Works in Handmade Soap


In my years of crafting natural soap, I’ve found that kaolin clay is a multi-functional addition. When incorporated into cold-process soap recipes, it disperses evenly, creating a creamy lather that feels indulgent on the skin. The clay also enhances the bar’s cleansing properties, gently lifting dirt and impurities without disrupting the skin’s natural balance.

Kaolin clay soap is particularly beneficial for individuals who find traditional soaps too drying or harsh. Its mild nature ensures a soothing cleanse, making it an excellent choice for those with sensitive or problem-prone skin.


Skin Type Benefits



Crafting Kaolin Clay Soap: My Process


When making kaolin clay soap, I begin with a blend of nourishing base oils such as olive oil, coconut oil, and shea butter. These oils provide moisture, conditioning, and a creamy lather. Once the soap batter reaches trace which is a key point in cold-process soap making when oils and lye have emulsified, I whisk in the kaolin clay. This ensures even distribution and a smooth texture throughout the bar.


The soap is then poured into moulds and left to cure for 4-6 weeks. During this time, the bar hardens, and its mildness increases, resulting in a long-lasting soap that’s kind to the skin.


Essential Oil Pairings


Kaolin clay soap pairs beautifully with various essential oils, allowing for a bespoke fragrance profile that complements the clay’s soothing properties. Popular choices include:


  • Lavender: Known for its No No, lavender adds a relaxing touch.

  • Tea Tree: Ideal for blemish-prone skin, tea tree oil provides natural antimicrobial benefits.

  • Geranium: Balances the skin while offering a floral, uplifting scent.


Kaolin Clay vs. Other Clays

When comparing kaolin clay to other clays used in soap making, its gentleness truly shines. Bentonite clay, for example, is highly absorbent and better suited for oily skin, while French green clay provides a stronger detoxifying effect. Kaolin clay, however, offers a balanced approach, making it suitable for most skin types without the risk of over-drying or irritation.


Its soft texture also makes it easier to work with during the soap-making process, ensuring a silky-smooth finish to the bar.


Safety and Sustainability


As with all natural ingredients, it’s important to use kaolin clay responsibly. Although it’s gentle, I always recommend patch-testing any new product, especially if you have sensitive skin or allergies. Our kaolin clay soap is formulated with an appropriate percentage to ensure a safe and effective cleanse.

From an environmental perspective, kaolin clay is sustainably mined and biodegradable, contributing to eco-friendly skincare practices. At The Humble Shepherd Co., we prioritise plastic-free packaging and minimal waste production to complement our use of natural ingredients.


Gentle Skincare for All


Kaolin clay soap is a wonderful addition to any skincare routine, offering a gentle touch that suits a variety of needs. Whether you’re looking for a mild cleanser for sensitive skin or a balancing bar for oily skin, this versatile ingredient delivers on all fronts.
