Homemade sunblock with zinc oxide

  1. 13 years ago

    Is it okay if I mix zinc oxide powder in my lotion to get an effective sunblock. I use Aveeno Daily Moisturizing Lotion (which is a great lotion). Also, would I have to preserve it in the refrigerator or something? Thanks for your reply. :)

    Hello Ria,

    If you have the correct ratio (which I do NOT know) for how much zinc oxide to how much lotion, I see no reason why you couldn't mix some zinc oxide powder into your lotion to increase its sunblock effectiveness.

  3. Thanks for this information. :)

  4. Can I mix zinc oxide with water and put it in a container then store in my purse? If so, what would be the shelf life of this mixture?

    Hello again Ria,

    I am NOT sure just how well zinc oxide mixes with water alone. Equally unsure about "shelf life."

    Whatever you use as a sunscreen should help block UV radiation AND help keep your skin moist. This combination is NOT likely to occur with a mixture of zinc oxide and water.

    The best sunscreens, containing sunblockers should contain a base of coconut oil, shea butter or some other natural oil.
