Sodium Ethylparaben is the sodium salt of Ethylparaben, a member of the paraben family. It is a widely used preservative in cosmetics and personal care products, known for its antimicrobial properties that help extend product shelf life. Commonly, it is added to creams, lotions, shampoos, conditioners, and makeup products. In its raw form, Sodium Ethylparaben appears as a white, crystalline powder or granules that is highly soluble in water - making it easier to incorporate into aqueous formulations. This ingredient is quite cost-effective as it provides reliable preservation at low concentrations. The chemical formula of Sodium Ethylparaben is C9H9NaO3.

What is SODIUM ETHYLPARABEN used for?
Sodium Ethylparaben is primarily used as a preservative and antimicrobial agent in cosmetics and personal care. It effectively inhibits bacteria, yeast, and mold, extending the shelf life of formulations. It is a versatile ingredient that can be found in products like creams, serums, conditioners, and shampoos - maintaining their integrity over time. Sodium Ethylparaben is also used in makeup, including foundations and mascaras, to ensure product stability during storage and use. Its water solubility makes it ideal for aqueous formulations, and its effectiveness at low concentrations enhances formulation efficiency.
Origin
Sodium Ethylparaben is synthesized by neutralizing Ethylparaben with a sodium hydroxide solution, converting the ester into its water-soluble sodium salt form. This enhances its solubility in aqueous formulations.
What does SODIUM ETHYLPARABEN do in a formulation?

PRESERVATIVESafety Profile
Sodium Ethylparaben is recognized as a safe ingredient up to the concentrations of 0.4%. Studies show low acute toxicity and minimal risk of skin irritation or sensitization. However, parabens, including Sodium Ethylparaben, have faced scrutiny for potential endocrine-disrupting effects due to their weak estrogenic activity. It is best to perform a patch test prior to full application.
