A foam booster is a specialized secondary surfactant engineered to enhance the overall performance, texture, and sensory appeal of liquid personal care and cleaning formulations. By stabilizing the structural integrity of bubble walls, it prevents rapid lather collapse in the presence of oils, dirt, and hard water, while simultaneously generating a richer, denser, and more luxurious lather. Additionally, it works synergistically with primary cleansing agents to build product viscosity and buffer potential skin irritation, ensuring smooth application, efficient coverage, and a high-end cleaning experience for the end consumer.
