ShieldBiso™ OMC: Pure Power, Light Feel

Sun protection has gone daily. Consumers aren’t just chasing high SPF anymore—they want protection that feels like nothing on the skin. ShieldBiso™ OMC (Ethylhexyl Methoxycinnamate) fits that need. Its high purity and strong oil solubility give formulators room to dial in a lightweight, non-greasy texture without compromising UV defense. Simply put, it’s the workhorse behind many daily-wear sunscreens.

Targeted UVB Protection

When it comes to UVB, OMC does what it’s supposed to do. Absorption peaks right around 310 nm. Batch BOMC260509 hits an extinction coefficient of 864 at 310 nm—a solid number that supports credible SPF claims. Whether it’s a morning commute or a weekend hike, that level of UVB coverage helps keep erythema and longer-term photo-aging in check.

Versatility for the “Sunscreen+” Era

The line between suncare, makeup, and haircare is blurring. OMC’s compatibility with esters, silicones, and ethanol makes it easy to slot into foundations, BB creams, or hair serums. It stays clear, doesn’t whiten, and won’t interfere with color or coverage. For formulators, that means fewer compromises between UV protection and aesthetics.

Purity That Translates to Texture

There’s a reason OMC remains popular: it doesn’t weigh formulas down. This batch shows 98.3% GC purity and a Hazen color of 40, keeping the base clean and low-viscosity. Vacuum distillation further refines the fluidity, so you can often back off on thickeners. The result is a lighter skin feel—something Asian markets, in particular, expect as standard.

Consistency You Can Build On

Behind the scenes, we keep things tight. Alkaline condensation plus high-temp vacuum distillation, stabilized with a touch of BHT, keeps peroxide levels low—this batch tested at just 0.1 mg/kg. That translates to predictable behavior, stable color, and less batch-to-batch drift. For R&D, it means fewer surprises and more time spent fine-tuning the final product.
