G-Block

G-Block UV-Grade Dispersions

One of the more difficult challenges in crafting a quality natural sunscreen is the delicate balance between skin transparency, broad spectrum protection.   G-Block products are natural dispersions engineered to provide the most efficient combination of high transparency, broad spectrum protection, and SPF performance in a very stable dispersion.  This stability not only speeds up the transition from laboratory batch to large-scale production, but also helps ensure that the SPF and critical wavelength levels remain consistent from one batch to another.

  • 100% natural ingredients - approved by COSMOS, Ecocert, and the Natural Product Association
  • Excellent active loading - high zinc oxide and titanium dioxide active concentrations while still retaining an easy-to-disperse viscosity profile
  • Globally compliant broad spectrum protection - meets the FDA broad spectrum labeling requirements as well as EU COLIPA and Japanese PF standards
  • Stress-free stability - no separation or settlement, resulting in consistent SPF and critical wavelength from batch to batch

Features & Applications of G-Block

Product Primary Application Secondary Application Features
G-Block DT 200 CCT
  • Color Cosmetics with SPF, BB, CC, DD creams
  • Premium Natural Sunscreens, Mass Market Natural Sunscreens, SPF 50, Organic UVB + Inorganic UV Filters
DT 200 CCT is a complementary dispersion, to be used primarily as a transparency and critical wavelength modifier. Use it in combination with other G-Block dispersions and organic UV filters to adjust transparency levels.
G-Block DTB 300 CCT
  • SPF 30+, Organic UVB + Inorganic UV Filters, Color Cosmetics with SPF, BB, CC, DD creams, Premium Natural Sunscreens
  • Mass Market Natural Sunscreens, SPF 50, Organic UVB + Inorganic UV Filters, Lip Balm
Our DTB 300 CCT is our flagship titanium dioxide dispersion for those who wish to avoid using zinc oxide. It is most suited for efficiently hitting high SPF targets as a primary UV filter and also works very well in combination with the DT 200 CCT and DZ 370 CCT to reach high levels of SPF 35-50. Creating specific combinations will give you the best compromise between cost and performance.
G-Block DZ 370 CCT
  • Premium Natural Sunscreens, Lip Balm, Mass Market Natural Sunscreens
  • Color Cosmetics with SPF, BB, CC, DD creams, SPF 50, Organic UVB + Inorganic UV Filters
For premium formulations, DZ 370 CCT has the best transparency and sensory performance, followed by DZ 480 CCT. The DT 200 CCT and DTB 300 CCT are more whitening due to their higher refractive index.
G-Block DZ 480 CCT
  • Mass Market Natural Sunscreens, SPF 30+, Organic UVB + Inorganic UV Filters, SPF 50, Organic UVB + Inorganic UV Filters, Color Cosmetics with SPF, BB, CC, DD creams
  • Premium Natural Sunscreens, Lip Balm
For mass market formulas, DZ 480 CCT is the most cost-effective solution for boosting SPF and critical wavelength, especially in combination with organic UV filters. The DZ 480 CCT is designed for mass market formulations, where the goal is hitting SPF and broad spectrum benchmarks at efficient price points without sacrificing much on sensory and transparency.

Superior Stability, Every Time

Standard Zinc Oxide Dispersion (A)

The typical zinc oxide dispersion features low active content and poor stability, leading to formulators constantly battling settlement issues along with inconsistent SPF results.

G-Block Dispersions, Stable and Consistent (B)

A G-Block dispersions are engineered to be extremely stable compounds, with no separation or synerisis developing over time.

As a result, you never need to remix a G-Block dispersion before use, and are far more likely to hit your SPF targets from one production batch to the next.
