INCI: Sodium PEG-7 olive oil carboxylate

What is Sodium PEG-7 olive oil carboxylate?

Sodium PEG-7 olive oil carboxylate is an anionic surfactant formed by reacting the fatty acids present in olive oil and esters from polyethylene glycol. It is a clear liquid with a slight characteristic odor, and it is mainly used as an ingredient in personal care products.

Use & Benefits:

Surfactant: Reduces the surface tension between two product components, such as two liquids or a liquid and a solid.

Cleansing Agent: Collects dirt, oil, and other pollutants that have accumulated on the skin's surface, which can then be readily rinsed away with water.

Foaming Agent: Creates foam in personal care products such as shampoos and conditioners.

Emulsifying Agent: Stabilizes the product, inhibits component separation, and allows for equitable dispersion of the product's components.

Hydrophilic and Hydrophobic: Of its two ends, one is hydrophilic and the other is hydrophobic in nature.

Prevents Infections: Aids in the cleansing of the skin and hair, as well as the prevention of infections such as acne and dandruff.

Versatile Ingredient: Used in formulations of shampoos, conditioners, facial cleansing products, and other bath products.
