What Is Cetearamidoethyldiethonium Succinoyl Hydrolyzed Pea Protein?

Cetearamidoethyldiethonium succinoyl hydrolyzed pea protein is a conditioning agent derived from pea protein. It combines plant-based amino acids with a quaternary ammonium compound, which gives it mild surfactant properties.

In skincare formulations, it functions primarily as a cleansing agent and antistatic ingredient. It helps remove impurities from the skin whilst conditioning and softening the skin barrier, rather than leaving it stripped or tight.

How It Works

This ingredient works through dual mechanisms. The surfactant component allows it to bind to oils and impurities on the skin surface, helping them rinse away with water. Simultaneously, the hydrolyzed pea protein fraction deposits a conditioning film that helps soften and smooth the skin.

Unlike harsher surfactants, it tends to be gentler because the protein component moderates the drying effect of the cleansing action, making it suitable for formulations intended to be mild.

Clinical Evidence & References

Published research specifically on this ingredient in skincare is limited. Its safety profile is well-established in cosmetic use, and it is widely accepted in mild cleansing products.

The conditioning benefits are supported by the general understanding of how hydrolyzed proteins and quaternary ammonium compounds behave in formulations, though direct clinical studies comparing its efficacy to other conditioning agents are not readily available in the public literature.

How to Use

This ingredient is typically found in cleansing products, including gentle face washes and micellar waters. Apply as directed by the specific product, usually morning and evening. Follow with your regular skincare routine. It works well in combination with other mild cleansing or hydrating ingredients.

Safety & Precautions

Generally well-tolerated and considered safe for use in cosmetic formulations. Patch test if you have very sensitive or reactive skin, as with any new product.
