Disodium Lauryl Sulfosuccinate

Disodium lauryl sulfosuccinate is a synthetic surfactant—a cleaning agent derived from lauryl alcohol and succinic acid. It belongs to a category of gentler surfactants designed to remove oil and dirt from skin whilst reducing the irritation potential associated with harsher cleansing agents.In skincare formulations, it functions primarily as a cleanser and foam booster, helping to lift impurities and create a light lather. It also has mild conditioning properties and can help stabilise formulations as a hydrotrope.

Surfactants work by having two opposing parts: one that attracts water and one that attracts oil. This dual nature allows them to suspend oil, dirt and makeup so they can be rinsed away with water. Disodium lauryl sulfosuccinate is structured to perform this function effectively whilst interacting less harshly with the skin's natural lipid barrier compared to harsher sulfates.The addition of the succinate component moderates the irritancy profile, making it a common choice in gentle cleansers and syndet bars designed for daily use.

Use as directed on the product label, typically as part of a daily cleansing routine. Apply to damp skin, massage gently, and rinse thoroughly with water. Because it is mild, it can be used twice daily, though once daily is sufficient for many people. If used in a bar cleanser, a small amount goes a long way.

Disodium lauryl sulfosuccinate is generally well-tolerated and widely used in skincare products. However, like all surfactants, it can potentially irritate if used excessively or left in prolonged contact with skin; rinse thoroughly after cleansing.
