Sunscreen & Tanning Lotion Testing
Light that is emitted from the sun contains radiation from three frequency bands which are infrared, visible and ultraviolet light. Sunscreens are designed to primarily block the ultraviolet band as it is considered to be the most dangerous. UVA, UVB, and UVC are the three categories that comprise the Ultraviolet (UV) radiation band. Since UVC radiation is typically blocked by earth’s atmosphere sunscreens that protect against a broad spectrum generally focus on UVA and UVB radiation.
SPF or sun protection factor compares the amount of time ones skin takes to redden while wearing the protection verse unprotected skin. Any consumer product that claims to be a sunscreen or have sun protection claims must be tested to measure the SPF of the product. Products that make waterproof claims must also be tested to verify their performance.
From products that are waterproof and sweat proof, products that moisturize without the slippery feeling of a lotion product, children’s products that contain aloe and vitamin E, to indoor tanning lotions that will not damage the acrylic surfaces used in tanning beds, Avomeen can both develop and test sunscreen/tanning products to your specifications.
