Case Study: Development of Reef-Safe, Waterproof, Mineral Sunscreen
With growing awareness of environmental and skin health concerns, One of our clients wanted to develop a reef-safe, waterproof, mineral sunscreen that combines high-performance UV protection with eco-conscious formulation. The project aimed to create two variants: a tinted sunscreen matching industry benchmarks and a non-tinted version, both adhering to strict criteria for safety, efficacy, and sustainability.
Key Objectives
SPF 50 with Broad-Spectrum Protection
Shield against UVA/UVB rays using mineral blockers.
Reef-Safe Formulation
Exclude oxybenzone, parabens, PABA, and fragrances to protect marine ecosystems.
Dual Variants
Tinted Version: Pigment matching benchmark cosmetics.
Non-Tinted Version: Clear, non-migrating formula.
User-Centric Features
Non-greasy texture, hypo-allergenic, waterproof, and long-lasting adherence.
Formulation Design
Primary UV Blocker Selection
The approved formulations prioritized zinc oxide as the primary mineral UV blocker, for reef safety and broad-spectrum protection.
Tinted Variant Development
Incorporation of Red IO2 and Yellow IO2 pigments to achieve a natural skin-matching tone.
Base Ingredients Selection
Coconut Oil (in one variant) and Sunflower Oil for moisturizing benefits.
A 3rd gen emulsifier and stabilizers to prevent migration and greasiness.
Vit-E (Tocopheryl Acetate) for antioxidant protection.
