EUROPIUM CHLORIDE.

Insufficient Data CAS 10025-76-0,13759-92-7 / SKIN PROTECTING

Europium Chloride is a rare earth compound primarily recognized for its distinct luminescent properties, widely employed across scientific research, optoelectronics, and diagnostic assays. While some cosmetic sources attribute a 'Skin Protecting' function to it, there is currently no established mechanism of action or specific skincare benefits supported by robust data.

Summary

Skin Protecting

Science

Mechanism of Action

Despite a listing as 'Skin Protecting' by certain sources, there is no established mechanism detailing how Europium Chloride interacts with skin or provides specific cosmetic benefits. Its known properties are predominantly luminescent, utilized in non-dermatological applications.

Europium Chloride lacks established clinical efficacy in skincare, rendering the concept of 'dusting' or specific concentration ranges for benefits inapplicable.

Stability

Europium Chloride, particularly its hexahydrate form, is stable yet notably hygroscopic, absorbing atmospheric moisture rapidly. Optimal storage requires a tightly closed container in a dry, well-ventilated area, preferably under an inert atmosphere (e.g., nitrogen or argon), to prevent prolonged exposure to air and moisture. The luminescence intensity of related Europium(III) complexes is sensitive to pH variations.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Unknown

Europium Chloride has not undergone thorough review by the Cosmetic Ingredient Review (CIR) Expert Panel for its safety in cosmetics, with some sources classifying it as 'not rated' or a 'new ingredient' lacking known cosmetic benefits. No specific SCCS assessment is available. Safety data sheets classify Europium(III) chloride hexahydrate as an irritant and environmental hazard under GHS, noting it may cause slight irritation to the skin and eyes, serious eye damage, and respiratory irritation. Ingestion or inhalation may pose health risks. An oral toxicity study in rats identified a no-observed-effect level (NOEL) of 200 mg/kg/day.

Verdict

Insufficient Data

Due to a lack of established skincare benefits and comprehensive safety data for cosmetic use, the inclusion of Europium Chloride in formulations is not currently recommended.
