As with all essential oil soaps, try a small amount on your inner arm first and check if it suits your skin; only then, go ahead and use it on the rest of the body.


Sodium hydroxide, often referred to as lye, is an alkaline substance extensively employed in the soap-making process. Alkali plays a crucial role in soap production by engaging in a chemical reaction with oils (fats), leading to the formation of soap through a process known as saponification. During this transformative reaction, sodium hydroxide completely interacts with oils and fats, converting from an alkali into soap. Notably, no traces of sodium hydroxide remain in the final product.


Saponification denotes the chemical process wherein a fat, oil, or lipid combines with an alkaline liquid to produce soap. In the case of many soaps, this involves the amalgamation of sodium hydroxide with an oil source. Our soap is meticulously crafted using coconut oil and essential oils, ensuring the absence of sodium hydroxide in the end product. These oils possess exceptional moisturizing attributes that make them ideal for soap production. The inclusion of sodium hydroxide results in more robust and long-lasting soap, enhancing the durability and utility of your bar soap.


Lactic acid is used in soap making as an additive to enhance the overall quality of the soap. It serves several purposes:

  1. Skin Conditioning: Lactic acid is known for its skin-friendly properties. When incorporated into soap, it can contribute to making the soap milder and gentler on the skin. It can help to moisturize and exfoliate, leaving the skin feeling soft and smooth.

  2. pH Adjustment: Lactic acid can be used to adjust the pH of the soap. Soap making involves a chemical reaction between fats or oils and an alkaline solution (such as sodium hydroxide). Sometimes, the resulting soap can be too alkaline, which may not be ideal for the skin. Lactic acid can be used to lower the pH and bring it closer to the skin's natural pH, making the soap more balanced and less harsh.

  3. Hardness and Texture: Lactic acid can impact the texture and hardness of the soap. It can help create a firmer bar of soap that lasts longer and doesn't dissolve too quickly when in contact with water.
