Our history

Publication ofAmendment 1:2026 to ISO 24443:2021 to be applied to the current document.

WENEOS offers maintenance and calibration of in vitro and in vivo solar simulators in compliance with current solar standards.

WENEOS offers the new innovative in-houseHDRS (Hybrid Diffuse Reflectance Spectroscopy) test method for assessing the photoprotection of sunscreen products in accordance with ISO 23698:2024 standard.

Publication of two new alternative methods for assessing the sun protection properties of cosmetic products.

• ISO 23675:2024 - Cosmetics: Sun protection test methods - In vitro determination of sun protection factor (SPF).
• ISO 23698:2024 - Cosmetics: Measurement of the efficacy of sunscreen products by diffuse reflection spectroscopy.

WENEOS moves into a new 800 m² building (RE2020) dedicated to solar protection evaluation.
