Sodium Lauryl Sulfate

Sodium lauryl sulfate (SLS) is a synthetic surfactant, meaning it helps to reduce surface tension between liquids. It is typically made from lauryl alcohol, which can be derived from coconut oil, palm kernel oil, or petroleum.

SLS is used as an emulsifier and a foaming agent in food products. It helps to blend ingredients that don't normally mix, like oil and water, and creates a foamy texture. It is often found in baked goods like cakes and cupcakes, and sometimes in processed fish.

In the United States, sodium lauryl sulfate is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is also used in personal care products, where it can cause skin irritation in some individuals. International bodies like JECFA have evaluated it, but no specific numeric limits are publicly available. Evidence regarding its health effects at typical food consumption levels is limited, and it is not considered a significant health concern by regulatory agencies.
