Cosmos-Certified UV Filter: SUNZNO-OLEO200

Oktrade is the exclusive distributor of Sunjin Beauty Science in Turkey, a world-leading manufacturer of micro-beads, coated pigments and mineral UV filters based in South Korea. With its third factory investment in 2019, Sunjin BS has become one of the world's largest manufacturers, particularly in zinc oxide and silica production, holding FDA, APII and GMP certificates. While Sunjin BS maintains its unique position in the cosmetics industry through continuous development of new raw materials with innovative formulations, SUNZnO-OLEO200 was launched in 2019 as a Non-Nano and COSMOS-certified mineral UV filter. The key feature distinguishing SunZnO-Oleo200 from competing products is its transparency. Despite its 200nm size and coating technology, it achieves transparency levels comparable to or exceeding many nano-based products. INCI: Zinc oxide & Cetyl alcohol Particle Size: 200 nm Features: • Non-Nano • COSMOS Grade • Transparent • Better UV protection, high SPF value

Coating Technology

Conventionally, the most common natural coating material has been fatty acid, but the ester functional group is susceptible to hydrolysis. Sunjin is the first company to introduce fatty alcohol coating to inorganic UV filters. This innovative approach results not only in more stable formulations but also prevents odour deterioration and yellowing problems that can occur through oxidation. Better Coating Stability

Oleo coating provides better dispersion in oil.

Other criteria to be considered when formulating and producing sun care products include: transparency of results, in-vivo and in-vitro testing to measure accurate and precise SPF and PA values, and hydrophobicity.
