Zinc oxide is una raw material with a physical filter, with antiseptic function and is used both on the skin of the bambino than for adults. It is a micronized product, not nanoparticles. Modo Use: | It is used in the preparation of creams for irritated skin exposed to maceration such as that of children, skin with acne, eczema and mycosis problems | Not suitable for sunscreens but recommended for creating after-sun products | In cosmetic preparations it should be dispersed in glycerin, stirring to dissolve it well, and added to a ready emulsion, at a temperature of around 40 | Percentage of use: 2-10% | Please note: the product is not suitable for the preparation of sunscreens as it is micronized and the dimensions of the particles it contains are of very different "sizes" from each other, this would entail the risk of not distributing them homogeneously on the skin and therefore of burning, while the zinc oxide used in sunscreens has particles of very similar sizes to each other, in modo to allow una homogeneous distribution. Furthermore, the zinc oxide particles used in sunscreens are coated with a fatty film (fatty acids) that allows una Better spreadability. We would like to point out that homemade sunscreens are generally not recommended because they would not be subjected to the necessary tests to determine their protection factor and would represent a risk to the skin. | Product type: raw material Suitable skin types: irritated, impure Brand: La Saponaria Features: Vegan Certified: Vegan without certification | Ingredients (INCI): Zinc Oxide
