Essentially Natural Sodium Lauroyl Sarcosinate (Perlastan L 30)

• Outstanding lather building, even at higher pH
• High resistance to sebum delathering
• Kind to skin, hair and eyes
• Lowers any irritation of other surfactants
• Skin and hair maintain good feel, softness and lubricity
• Improves moisture retention in skin
• Provides good wetting and detergency
• Blasts through grease and grime
• Environmentally friendly
• Highly biodegradable (aerobic and anaerobic)

Normally used as a secondary surfactant at 1 -5% to increase the mildness and boost foam of foaming formulations. To aid stability of the final formulation, the pH should be greater than 6.

Can be thickened with salt. Becomes viscous at pH 5, so you can also thicken by adding citric acid solution and testing to pH 5.

Readily biodegradable.

ASM: 29 - 31%

pH: 8 - 9.3

Anionic

A note on sodium lauroyl sarcosinate and acids:

Sodium lauryl sarcosinate is made from sarcosine, an amino acid (building block of protein). Certain acids such as lactic acid and glycolic acid can denature proteins, and turn this surfactant milky. Therefore we advise against using sodium lauroyl sarcosinate with lactic or glycolic acid.

Other powder acid forms such as citric acid etc seem to be fine.

Note: A Certificate of Analysis (COA) is a document sharing the outcomes of a scientific test. It helps us verify that a product meets the specified standards. These tests are conducted on product batches, so slight variations in results between different batches are normal. If the batch number on this COA doesn't match the one on the product you bought from us, please get in touch with us. This is just one recent instance.
