G-Block™ DZ 370 CCT

G-Block™ DZ 370 CCT is an Ecocert and NPA-approved zinc oxide dispersion for broad-spectrum sunscreen formulations. This dispersion has a critical wavelength over 370nm, allowing formulators to pass the broad-spectrum wavelength test without the need for additional UV filters. It contains the highest concentration of zinc oxide for natural physical UV dispersions in the industry (70%), while still retaining good skin sensory qualities and strong transparency. DZ 370 CCT is also very stable, which creates reliably consistent SPF and critical wavelength results from one batch to the next.

Features and Benefits

For premium formulations, DZ 370 CCT has the best transparency and sensory performance, followed by DZ 480 CCT. The DZ 370 CCT is engineered to provide the best balance between transparency and broad spectrum protection.

Easy Manufacturing

  • Stable product, no separation and no sedimentation.
  • Easy to transfer and to mix with the common cosmetic equipments.

 

Easy Formulation/product development

  • COSMOS, ECOCERT and Natural Product Association (NPA) approved for natural sunscreens which meet with global regulations.
  • Meet with global UVA criteria: FDA of USA: critical wavelength > 370 nm; PA +++ of Asia; UVAPF/SPF > 1/3 of EU
  • Speed to market: Provides the guide equations to calculate the appropriate % dosage for the target SPF and critical wavelength for quick formulation development.
  • Extremely high % active for flexible formulation development with good sensory.

Usage Guidelines

Just add into the oil phase of the formulation and mix well.

Dosage: About 1.5 SPF per 1% ZnO active. Critical wavelength 371 - 373 nm. For example, a SPF 30 sunscreen formulation would need: 30/1.5 = 20 % ZnO active, or about 28.6% G-Block DZ 370 CCT (28.6% x 70% = 20% ZnO active).

For predicting the SPF and critical wavelength of sunscreen prototypes made of the blends of several GBlock products, please contact us for the "G-Block Prediction Calculator" program to do it easily.

Sunscreen Test Protocols:

SPF: In-Vivo Protocols of FDA of USA and EN ISO 24444:2010.

UVA: In-Vivo protocol of EN ISO 24442:2011; In-Vitro Protocol of FDA of USA( critical wave) ; EN ISO 2443:2012 (UVAPF) .

Please note that in-vitro SPF measurement is not suitable for sunscreens of inorganic UV filters
