Sodium Lauryl Sulfate vs. Sodium Lauroyl Sarcosinate: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Sodium Lauryl Sulfate (SLS) is a harsher surfactant used in cleaning products, while Sodium Lauroyl Sarcosinate is gentler, often used in personal care items.
Key Differences
Sodium Lauryl Sulfate (SLS) is a synthetic detergent known for its robust cleaning and foaming properties. Sodium Lauroyl Sarcosinate, in contrast, is a mild, biodegradable surfactant derived from natural sources, offering gentler cleansing effects. Both are used in various personal care and cleaning products, but SLS is more common in heavy-duty cleaners due to its stronger nature.

Sodium Lauroyl Sarcosinate is often chosen for its compatibility with the skin, minimizing irritation. Sodium Lauryl Sulfate, however, is known for its potential to cause skin and eye irritation in sensitive individuals. This makes SLS less suitable for products intended for sensitive skin, whereas Sodium Lauroyl Sarcosinate is often used in hypoallergenic formulations.

In terms of environmental impact, Sodium Lauroyl Sarcosinate is considered more eco-friendly, breaking down more easily in the environment. Sodium Lauryl Sulfate, on the other hand, can be more difficult to degrade, posing a greater environmental risk. Consumers often prefer Sodium Lauroyl Sarcosinate in eco-conscious products.

Sodium Lauryl Sulfate is known for its ability to create a rich lather, making it popular in shampoos and soaps. Sodium Lauroyl Sarcosinate, while also capable of lathering, produces a less intense foam and is often used in products where gentleness is prioritized over lather, like facial cleansers.

Cost-wise, Sodium Lauryl Sulfate is typically cheaper and more widely available, making it a common choice for mass-market products. Sodium Lauroyl Sarcosinate, being derived from natural amino acids, can be more expensive, and is often found in premium or specialized personal care products.
