G-Block™ DT 200 CCT

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.

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
• 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

Cosmetic and Toiletry:

• Natural sunscreens that meet with all global regulations for broad spectrum (with G-Block DTB 300 CCT) and “natural” standards. Sunscreens for baby and people with sensitive skin.
• Sport sunscreens with long lasting UV A (with G-Block DTB 300 CCT) and B protection.
• Daily skin care lotion and cream with UV A (with G-Block DTB 300 CCT) and B protection.
• Natural Color cosmetics with sunscreen benefit.
• Color Cosmetics with SPF protection
• BB, CC, DD creams
• SPF 50 in combination with organic UVB filters

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

Dosage: About 3 SPF per 1% TiO2 active; Critical Wavelength 365 nm. For example, SPF 30 sunscreen would need: 30/3 = 10% TiO2 active or 22.3% G-Block DT 200 CCT (22.3% x 46% = 10.2% TiO2 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
