GreenShield SPF
Revolutionizing Sun Protection through Circular Science
The Innovation: A Two-Fold Approach
Our collaboration with Plinius Labs focused on replacing synthetic ingredients with circular, bio-based alternatives:
WonderLime (Upcycled CaCO₃): We transformed low-value eggshell waste into high-purity Calcium Carbonate particles. These "tuned" particles act as a natural SPF booster, enhancing the effectiveness of the UV filters.
100% Bio-Based UV Filters: We successfully synthesized Ethylhexyl Salicylate (EHS) from renewable sources. This provides a green, identical replacement for the standard petrochemical version, ensuring 100% renewable carbon content.

Using in-house SPF testing methods, the GreenShield formula demonstrated promising UV protection properties, proving that ‘green’ can perform just as well as ‘synthetic.’
Key Results & Impact
Validated Performance: Using in-house SPF testing methods, the GreenShield formula demonstrated promising UV protection properties, proving that "green" can perform just as well as "synthetic."
Circular Economy in Action: By upcycling eggshells, we reduce food industry waste and turn it into high-value cosmetic ingredients.
Antioxidant Benefits: Beyond UV protection, the eggshell membrane proteins used in the process offer natural antioxidant and anti-aging properties.
