Sodium Lauroyl Sarcosinate

Sodium lauroyl sarcosinate is a mild anionic surfactant used in cosmetic formulations to provide effective cleansing with improved skin tolerance.

Key benefits

Effective cleansing
Improved mildness vs traditional anionics
Good foam performance
Supports balanced formulations

Behaviour in formulations

It reduces surface tension to remove dirt and oils and works with other surfactants to balance cleansing strength and mildness.

Add to the water or surfactant phase with mixing until uniform. Avoid excessive aeration.

Use level considerations

Use Rate (Min): 3.0
Use Rate (Max): 15.0

Sodium lauroyl sarcosinate is typically used at 3–15% depending on formulation type and desired cleansing strength.

Facial cleansers: 3–8%
Body wash: 5–12%
Shampoo: 5–12%

Often combined with amphoteric surfactants to improve mildness.

Starter Use Rate: 5–10% for most cosmetic formulations

Typically used at 3–15% depending on system.

Formulation summary

Sodium lauroyl sarcosinate is used as a primary or supporting anionic surfactant to provide effective cleansing while maintaining a milder skin feel compared to traditional anionic systems.

It is typically combined with amphoteric surfactants such as cocamidopropyl betaine to improve mildness and foam balance, and can be used alongside non-ionic surfactants such as coco-glucoside to further soften the system.

In formulation, it contributes cleansing strength and foam while allowing the overall system to remain more balanced and less harsh. It is particularly useful where stronger cleansing is required without compromising skin comfort.
