更完美的防曬產品

6月初時, 參加我舊老闆的退休party, 他是一位生物系教授, 他的徒孫做了些科研演講, 其中一位博士生Miss Mana Yung 的題目我好有興趣:

"Can your sunscreen caused wrinkles?"

她的防曬研究集中使用不同種類的氧化鋅Zinc Oxide作為防曬煤介:

1. Bulk ZnO

2. Uncoated ZnO-NPs

3. 3-Aminopropyltrimethoxysilane – coated ZnO-NPs (A-ZnO-NPs)

4. Dodecyltrichlorosilane – coated ZnO-NPs (D-ZnO-NPs)

5. ZnSO4

她發現Z-cote HP1是在各種防曬材料中表現最好的, 若加上維他命E, 加強抗氧化, 可減少自由基對細胞的影響.

Quote from her talk:

From the experiment results, Z-cote HP1 is more oil soluble than uncoated zinc oxide nanoparticles, and less ROS is produced. ROS stands for reactive oxygen species. These chemicals are highly active and they can cause cell aging and even damage DNA.

Information of Z-Cote HPI from internet:

An innovative form of microfine zinc oxide, with a particle size of less than 0.2 microns, Z-Cote is invisible when applied to the skin. Z-Cote is a physical, inorganic ingredient that is ideal for hypo-allergenic formulations making it an ultimate choice for your salve, lip balm, mineral makeup and skin protectant

所以我買了這材料回來(運送中), 希望做到更完美的防曬產品
