Z-Cote Zinc Oxide

# KR-401

ON THIS PAGE, YOU ARE PURCHASING THE Z-COTE ZINC OXIDE. If you would like to purchase the HP1 Z-Cote, please click here: HP1 Z-Cote.

We offer two kinds of Z-Cotes:


  • hydrophilic (dispersible in water)
  • uncoated
  • inorganic ingredient that is ideal for hypo-allergenic formulations
  • does not cause allergic reaction
  • Recommended to easily disperse into an Oil in Water emulsions (typical of a "natural/homemade" lotion)

HP1 Z-Cote:

  • hydrophobic (dispersible in oil; a.k.a fat loving)
  • coated with Dimethicone
  • compatible with all oil phases
  • Recommeded for a loose powder formulation because it will tend to not absorb the moisture in the air over time which would result in a clumpy powder.
  • Recommended to easily disperse into a Water in Oil emulsion (typical of a commercial/high performance lotion which has more oil - including silicone oils.

All Z-Cotes are microfine zinc oxides with a particle size of less than 0.2 microns (200 nm). As a result, these Z-Cotesare transparent,non-staining, non-greasywhen applied to the skin by using them alone or mixing them in cosmetic formulas yet still offer both broad-spectrum UVA and UVB protection.

We recommend Z-Cote for sun protection. However, be reminded that if you make a formal claim as to SPF protection of a product which you sell, you are considered by the FDA to be selling an over-the-counter drug. The FDA would require you to conduct independent testing of your product to confirm the SPF rating which you are marketing.

Sunscreen Approval Status and Usage Limits:

  • US: up to 25% Zinc Oxide
  • EU: up to 10% Zinc Oxide
  • Japan: Zinc Oxide approved with no limit
  • Australia: Zinc Oxide approved with no limit

Customer Reviews
1s1s1s1s1sNice and Sheer
By Susan
Z Cote was one of the reasons for my first order from TKB. I use a large percentage of Zinc Oxide in my personal formulations. This is very sheer is comparison to the regular Zinc Oxide I have used in the past. As a result my foundation is lighter weight and more shear. I love it!!

1s1s1s1s1sLove Z Cote!
By Jessica
This makes a great sheer foundation - and is especially good for women with darker skin tones as it doesn't make your foundation white like regular ZO.

By Holly
My husband refuses to touch regular sunscreen. REFUSES. And he works outdoors sometimes. So I put a bunch of this in with his regular Lubriderm lotion and lo and behold, it worked just as well as the SPF 30 I usually try to put on him. Z-Cote in lotion has much less of that heavy sunscreen ick feeling. Z-Cote is fabulous in foundation formulas too- I always add some and I never have to worry about sunblocking my face.

By Karen
I make my own sunscreen @ 22 -25% ZnO. I tried this based on others reviews and frankly, it leaves me very white.
