Executive Summary White Sapphire® outperforms nylon-12 on the metrics that matter: 44% stronger adhesion to skin, plus matched oil control and mattifying performance in long-wear systems. Nylon-12 does not biodegrade. It persists as a solid plastic particle indefinitely, and that persistence has been linked to skin penetration, inflammation, and oxidative stress in lab studies. Nylon-12 is already on a regulatory phase-out clock under REACH, with rinse-off products banned fro

Long-lasting formulations start with the right oil-control ingredient. Here's how White Sapphire® uses surface area and oil absorption capacity to deliver measurable, long-wear performance: Executive Summary Grade selection made simple: White Sapphire® Matte is the answer for formulations where oil control and a dry, non-greasy finish are the priority The real cost of sebum breakdown: wear time in colour cosmetics, effective SPF in sunscreen The physics behind oil control: ho

Talc is now Category 1B under ECHA and Group 2A under IARC, with an EU cosmetics ban expected around 2027 and J&J holding roughly $11 billion in litigation reserves. White Sapphire® is a manufactured, FDA-approved, COSMOS-certified talc alternative that matches talc's mattifying and adhesion performance in colour cosmetics and suncare, without the asbestos cross-contamination risk built into how talc is mined.

If you're formulating with talc, boron nitride, nylon, or silica, White Sapphire outperforms all four on adhesion to skin. Here's what the data shows. How White Sapphire® Compares Compared ingredient White Sapphire® adhesion advantage Boron nitride 19% stronger adhesion Talc 29% stronger adhesion Nylon 44% stronger adhesion Silica 64% stronger adhesion White Sapphire® has been tested for adhesion across multiple substrates and methods, and the results place it clearly above t

Specular reflection makes lines and pores visible. White Sapphire® suppresses it. Here is how the mechanism works and where it applies in formulation. The Optical Challenge White Sapphire® Was Built to Solve Suppressing specular reflection without sacrificing transparency is one of the harder balancing acts in complexion formulation. Increase the diffuse reflection and the finish goes chalky. Prioritise transparency and the soft-focus effect disappears. Most standard fillers

If you're formulating with zinc oxide, White Sapphire can push your SPF higher without increasing your zinc concentration. Here's how it works. The SPF Boosting Mechanism White Sapphire increases diffuse light transmittance through the formulation. Diffuse transmittance scatters light in multiple directions rather than allowing it to pass straight through. In a sunscreen formulation, this increases the path length of UV photons through the product, giving the zinc oxide activ

White Sapphire is available in two COSMOS certified variants. This guide covers the functional differences between Matte and Glow and which suits your formulation.

White Sapphire® is a mineral cosmetic ingredient that controls oil, improves adhesion, softens fine lines, and boosts SPF output in zinc oxide formulations.
