Zinc oxide powder has many uses, especially for topical application in beauty products. This compound appears as a white substance that is insoluble in water. Due to the nature of this product, you should avoid any type of inhalation when handling, because it can cause irritation to the respiratory tract. Unlike dietary zinc, which is crucial to a properly functioning body, you should never consume zinc powder, which can contain toxic chemicals, such as lead. Getting the appropriate zinc powder to suit your needs requires caution and the proper research.
Step 1
Purchase pharmaceutical grade, also referred to as USP, zinc powder from a reputable seller. Using zinc powder topically for homemade sunscreen, lotion or other applications, requires purity of the product. Avoid buying zinc powder online and buy in-store to thoroughly read the label and contents. USP grade zinc oxide guarantees the quality and purity of a substance.
Step 2
Research different brands of zinc powder using reputable online or print sources, such as government or educational-based publications. Some zinc powders may be more hazardous than others.
Step 3
Avoid combining any zinc powder with other household items, which may already contain the substance. Zinc oxide powder is a regular ingredient in many skin products, such as baby powder, ointments, shampoo and barrier creams. Too much of this compound may cause an adverse reaction.
Step 4
Wear gloves and a face mask when handling zinc powder to avoid any health hazards.
