S-Block

Combining Clean Ingredients with Clinical SPF Protection

S-Block DZ 100 PDCC is a new zinc oxide dispersion designed to meet growing consumer demand for multi-functional sun care products that combine clinically-validated claims with cleaner ingredients. The intersection between clean beauty and clinical treatment has created new product design problems that traditional silicone-based dispersions weren’t intended to solve. S-Block addresses these issues by giving formulators the ability to add consistent broad spectrum mineral SPF protection while moving freely between high performance silicone-based, hydrocarbon-based and clean beauty compliant emulsion and anhydrous systems. This makes S-Block a great fit for a wider range of sun care applications that need medical grade performance with brand-specific ingredient requirements. It features:

  • “Sensory”- Block Boost

Creates a unique, powdery smooth feeling during rub-in. Excellent sensorial enhancer, reducing dry-down, helps detackify formulations without requiring additional silicone powder.

  • Formulation Flexibility with Clean Ingredients

Compatible with all emulsion and anhydrous systems, making it easy to formulate for clean, clean clinical, or premium performance clinical products.  This formulation versatility combined with the unique sensory profile reduces dependency on silicone or siloxane-based dispersions.  

  • Clinical Grade Broad Spectrum Protection

 Meets the FDA broad spectrum labeling requirements as well as EU COLIPA (UVAPF/SPF = 0.46) and Japanese PF        standards (PA ++++).

  • Excellent Active Loading + Stress-Free Stability

High zinc oxide active concentration (78%) while still retaining an easy-to-disperse viscosity profile. No separation or settlement, resulting in consistent SPF and critical wavelength from batch to batch.  This leads to faster scale-up from lab, to pilot runs, and up to full manufacturing, increasing your brand's speed to market.  It also improves shelf stability as well, reducing pH drift and in-packaging rising viscosity issues associated with zinc oxide.

The Applechem Difference

A good dispersion is more than a simple mixture. Our expertise in
polymer science and chemical engineering allow us to customize
the architecture of natural polymeric dispersants and in-situ coating
systems. This creates more control over the density and distribution
of zinc oxide aggregates as well as the dispersion stability profile.
In other words, we can develop more concentrated, stable products
that resolve traditional formulation issues linked to poor dispersions.

(A) Conventional Zinc Oxide Dispersion


The typical zinc oxide dispersion features low active content and poor
stability, leading to formulators constantly battling settlement issues
along with inconsistent SPF results. Lack of uniformity in aggregate
size combined with uneven agglomerations leads to negative sensory,
poor transparency, and difficulty remixing back into a homogenous
state.


(B) S-Block DZ 100 PDCC


S-Block dispersions are engineered to be extremely stable compounds,
with no separation or synerisis developing over time. Zinc oxide
aggregates are more uniform and evenly distributed, improving
sensory, transparency, and SPF consistency.
