THE STORY OF NANOSUN EHMC
Nanosun EHMC: The UV-B Shield for Everyday Sun Protection
Nanosun EHMC is a globally used UV-B sunscreen filter, known for absorbing harmful UV-B rays responsible for sunburn, tanning, and photoaging.
It is oil-soluble, highly compatible with emulsions, and widely used in sunscreens, day creams, BB creams, lotions, foundations, and outdoor skincare.
A key molecule for enhancing SPF performance.
An Ester-Based UV Filter Engineered for High Stability & Oil-Phase Performance
Nanosun EHMC is created by esterifying methoxycinnamic acid with 2-ethylhexanol, producing a lightweight, oil-soluble UVB absorber.
Key features:
- Excellent photostability
- High UVB absorption (peak ~310 nm)
- Compatible with most oil-phase sunscreen systems
TRCkem supplies cosmetic-grade Nanosun EHMC with high purity for sun-care formulations.

Reliable & Oil-Soluble — Ideal for Modern SPF Formulations
• Typical use level: 3–10% depending on SPF target
• Add in the oil phase during emulsification
• Works well with: Avobenzone, Octocrylene, Zinc Oxide & other filters
• Stable under normal storage conditions
• Not recommended for baby-only formulations in high amounts
• Avoid overheating (>80°C) to prevent degradation
• Store in sealed containers away from light & heat
Formulator’s Queries, We Answered
1) What is Nanosun EHMC? What is its CAS number and INCI name?
Nanosun EHMC is the trade name you will use for the UV-B filter commonly known as octyl methoxycinnamate / octinoxate. Its INCI name is Ethylhexyl Methoxycinnamate and the main CAS number used in regulatory listings is 5466-77-3
2) What does Nanosun EHMC do in personal-care products?
Nanosun EHMC is a UV-B absorbing organic filter used in sunscreens and many leave-on and rinse-off cosmetics to reduce UV-B-induced skin damage and sunburn. It is commonly combined with other UV filters or photostabilizers to broaden protection.
3) Is Nanosun EHMC the same as “OMC” or “EHMC”?
Yes. OMC (octyl methoxycinnamate), octinoxate, and EHMC (ethylhexyl methoxycinnamate) are used interchangeably in industry literature — they refer to the same chemical family and typical material used as a UV-B filter
4) What concentration is considered safe for consumer products?
The European Scientific Committee on Consumer Safety (SCCS) recently concluded that Ethylhexyl Methoxycinnamate (EHMC) is safe as a UV filter up to 10% in finished cosmetic products when used under the assessed conditions (sunscreen lotion, face/hand cream, lipstick, sprays, etc.). If you plan to market Nanosun EHMC at or above that level, ensure your formulation and labeling follow the jurisdictional safety dossier requirements.
5) What about endocrine-disruption and systemic absorption concerns?
Recent reviews and regulatory opinions note that EHMC shows endocrine-active signals (weak estrogenic and anti-androgenic activity in some studies), and there is evidence that organic sunscreen filters can be systemically absorbed and detected in blood in human studies. Regulatory safety opinions have evaluated those data when setting use limits and conditions. Product developers should rely on up-to-date safety dossiers and post-market surveillance data
