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.
- “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. Suitable for Clean at Sephora, Conscious Beauty at Ulta, and Credo Clean.
- 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.
Applechem’s expertise in polymer science and chemical engineering allow them to customize the architecture of natural polymeric dispersants and in-situ coating systems, which creates more control over the density and distribution of zinc oxide aggregates as well as the dispersion stability profile. This leads to the development of more concentrated, stable products that resolve traditional formulation issues linked to poor dispersions.
- Product Benefits
Multi-Functional Premium Suncare
- Unique powdery smooth sensory
- Excellent transparency
- High ZnO content with low, pourable viscosity creates better control over texture and sensory
- Highest UVA protection (PA ++++) for clinical grade broad spectrum claims
- Inherent water resistance - reduces film former usage which improves product sensory
- Strong skin conditioning benefits for healthier skin
Unmatched Versatility
- Compatible with silicone, hydrocarbon, or natural systems (anhydrous + all emulsion-types)
- Unique sensory profile and formulation versatility reduce dependency on silicone or siloxane- based dispersions
- Easily formulate for clean, clean clinical, or premium performance clinical products
Faster Speed to Market
- Better stability means easier and faster scale-up from lab to pilot to manufacturing.
- No remixing required - consistent active concentration means reproducible SPF and broad spectrum performance from batch to batch.
- Improved shelf stability - reduces pH drift and in-package rising viscosity issues associated with zinc oxide

- Processing Instructions
Mix with oil at the beginning of the oil phase. Depending on the oil type:
- Hydrocarbon/Ester Oil Phase only - mix using dispersion blade, homogenizer is not necessary
- Silicone-containing Oil Phase - blending with a homogenizer is highly recommended
- Blended Silicone/Hydrocarbon/Ester Oil Phase - Mix S-Block with hydrocarbons and ester oils first, then add silicone and homogenize
- Can be used in cold processing.

Technical Details & Test Data
- 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.- Particle Settlement Test
The goal of this test was to determine the overall suspension power and stability profile of S-Block verses a panel of traditional silane- coated dispersions. Samples were subjected to a long-term stability test for 30 days at 50 Celsius. A spatula was then inserted to scrape the bottom for potential settlement residue. S-Block was the only dispersion that did not exhibit zinc oxide particulate settlement issues. The other dispersions were only stable for one week, and exhibited settlement behavior even at room temperature storage.

LECITHIN (AND) SILICA- Oil Phase Compatibility Test
This test was conducted to determine the general compatibility of S-Block with the three main oil classes (silicone/hydrocarbon/ natural esters) in comparison to the above conventional silicone-based coated zinc oxide dispersion. Samples of the dispersions were mixed with the carrier oil and then poured out to examine residue for synerisis.
Popular Conventional Silicone Dispersion
No synerisis when dispersed into volatile silicone, but displays clear evidence of incompatibility in hydrocarbon and natural esters.S-Block DZ 100 PDCC
No evidence of synerisis when mixed in either silicone, hydrocarbon, or natural ester.
