Symrise, in partnership with Kobo, a company that specializes in powders and dispersions related to color cosmetics and mineral UV filters, has developed a mineral UV filter range and will market the cosmetic ingredients under the brand Neo Heliopan.

This adds to its portfolio of existing sun filters. The Neo Heliopan range consists of two surface-treated powders, namely:
- Neo Heliopan ZnO 40 (INCI: Not Provided), which provides broad-spectrum UV protection with a focus on increasing SPF; and
- Neo Heliopan ZnO 300 (INCI: Not Provided), which provides broad-spectrum UV protection with a focus on increasing the UVA-PF.
Neo Heliopan ZnO 40 and Neo Heliopan ZnO 300 form a combination for formulas focused on sun protection, such as face creams. The first of these provides effective UVB protection with a minimal white cast due to its fine particle size. The second offers balanced UVA protection due to its larger particle size.
Symrise presented three sunscreen concepts containing the Heliopan range at in-cosmetics 2022:
- Daily face cream (o/w), with only mineral UV filters;
- Kids sunscreen (w/o), with only mineral UV filters; and
- Hybrid sunscreen for sports (w/), combining mineral and synthetic UV filters.
“Formulators get considerably challenged when dispersing zinc oxide in the oil phase," said Ev Suess, global head of business unit sun protection, functionals and colors. "They need to expend a big amount of mechanical energy with crude zinc oxide. We have surface-treated our powdered form of Neo Heliopan ZnO 40 and Neo Heliopan ZnO 300. Manufacturers can now process their products faster and with less dust."
This results in a more sustainable production process that uses significantly less energy, the company reports.
