Common questions

Can SEMITI NANO-30 powder replace Croda Solaveil CT-300 dispersion directly?+
Not as a direct drop-in — Solaveil CT-300 is a pre-dispersed 50% dispersion in C12-15 alkyl benzoate; SEMITI NANO-30 is the underlying powder. For equivalence: 1 kg Solaveil CT-300 ≈ 0.7 kg SEMITI NANO-30 + 1 kg your chosen carrier. Requires in-house pre-dispersion capability.
How does SEMITI NANO-30 cost compare to Solaveil CT-300 on an active TiO2 basis?+
Solaveil CT-300 carries premium Croda pricing reflecting branding and pre-dispersion. SEMITI NANO-30 + carrier delivers the same active TiO2 at significantly lower cost per kg of active ingredient. For high-volume sunscreen producers, the cost advantage of in-house dispersion is substantial.
When should I choose Solaveil CT-300 over SEMITI NANO-30 powder?+
Choose Solaveil CT-300 when: (1) you are a boutique sunscreen brand without high-shear mixing equipment for pre-dispersion, (2) you prefer a ready-to-use drop-in ingredient with Croda technical support, or (3) you have a Croda supply relationship that provides regulatory or marketing value. For larger producers with in-house dispersion capability, SEMITI NANO-30 + own carrier is the cost-optimal route.
