SODIUM LARDATE
Description
Sodium Lardate is a unique soap-forming ingredient derived from lard, a rendered form of pork fat. This specialty surfactant is classified as a fatty acid salt, specifically the sodium salt of lardic acid. Its chemical structure consists of long-chain fatty acids bound to sodium ions, giving it both hydrophilic and hydrophobic properties essential for cleansing.
In skincare formulations, Sodium Lardate functions primarily as an emulsifier and cleansing agent. It helps create a stable lather and aids in removing dirt, oil, and other impurities from the skin surface. Unlike some harsher synthetic surfactants, Sodium Lardate tends to be milder and less likely to strip the skin's natural oils.
This ingredient is particularly valued in traditional and artisanal soap-making for its ability to produce a creamy, stable lather and contribute to a firm bar texture. It also imparts a smooth, silky feel to the skin after use. However, its animal origin makes it unsuitable for vegan or vegetarian-friendly products.
Formulators should be aware that Sodium Lardate's effectiveness can vary depending on water hardness and pH levels. It's often combined with other surfactants to optimize cleansing performance and lather quality in various skincare products.
