A formulation for a solid hair cleanser, designed to be free of sodium hydroxide or potassium hydroxide, which are commonly known as lye, characterizes a cleansing bar production process. This approach typically involves substituting ingredients that offer cleansing properties and pH balance without the need for saponification, the chemical reaction that occurs when lye is mixed with fats and oils. An example would be combining solid surfactants with conditioning agents, essential oils, and botanical extracts to create a solid form cleanser.
Avoiding the utilization of lye in solid hair cleanser production caters to individuals seeking milder formulations, potentially reducing scalp irritation and dryness. Historically, the concern around lye stems from its caustic nature; if not properly reacted during saponification, residual lye can cause skin damage. A formulation that bypasses this process offers a perceived safety advantage and allows for greater control over the final product’s pH and conditioning properties.
