Common questions
Can SEMITI NANO-30 substitute Merck Eusolex T-2000 directly in a sunscreen formula?+
Yes — both have matched primary particle size (15–30 nm vs 15–25 nm), silica-based surface coating, and SPF efficiency of 30–35 at 8% loading. Pre-disperse SEMITI NANO-30 in your preferred carrier, run SPF testing (ISO 24444 in vivo for label claims), and confirm consumer panel acceptance. Typical qualification: 4–8 weeks.

Merck Eusolex T-2000 commands premium pricing at USD 30+/kg; SEMITI NANO-30 lands at USD 12–18/kg — approximately 50% lower. For Asia-Pacific sunscreen brands producing at volume, this cost difference is highly material to margin.
When should I keep using Merck Eusolex T-2000 rather than switching?+
Keep Eusolex T-2000 when your brand sells in EU/US markets where Merck ingredient qualification has regulatory or marketing value, or when your sunscreen is a premium pharmaceutical-grade product with a tight Merck-specific qualification requirement. For mid-market and Asia-Pacific cosmetic brands without a Merck lock-in, SEMITI NANO-30 delivers matched SPF performance at half the cost.
