Your needs: analyze the sun filters of your cosmetic products
What are sunscreens?
Sunscreens provide photochemical protection by absorbing the energy of ultraviolet rays to protect the skin. The two types of filters (against UVB & against UVA) are generally combined in a suncare product to guarantee its effectiveness.
Why should you use sunscreens in your cosmetic products? They guarantee the safety of users, the use of sunscreens in cosmetic products is highly regulated.
Annex VI of the Cosmetic Regulation 1223/2009 sets the positive list of UV filters. 27 UV filters are currently authorized, including 3 filters in nanometric form.

FAQ
Sunscreens are devices designed to protect the eyes or skin from the harmful effects of the sun's rays. They are used to reduce exposure to the sun's ultraviolet (UV) rays, which can be harmful to the skin and eyes.
Sunscreens for the skin are commonly referred to as sunscreens or sunblocks. They are designed by the cosmetics industry to be applied to the skin. They contain ingredients that absorb, reflect, or scatter UV rays. They thus reduce the risk of sunburn, premature skin aging, and skin cancer. They are available in various formulas, such as lotions, creams, gels, and sprays, with varying levels of SPF (Sun Protection Factor).
The use of sunscreens is important to prevent damage caused by excessive sun exposure, including sunburn, wrinkles, and premature skin aging. For effective protection against the sun's rays, it is essential to choose quality products suited to your skin type or specific needs.
Sunscreens, used to protect the skin from the sun's harmful ultraviolet (UV) rays, are manufactured by combining different active ingredients and excipients. Here are the main steps in the manufacturing of sunscreens for the skin:
- Selecting the active ingredients: Active ingredients are the components that absorb or reflect UV rays. There are two types of active ingredients commonly used in sunscreens: chemical filters and mineral filters. Chemical filters absorb UV rays, while mineral filters (such as zinc oxide and titanium dioxide) reflect UV rays. The choice of active ingredients depends on the specific sunscreen formula.
- Blending the ingredients: Active ingredients are blended with other components such as oils, emulsifiers, thickening agents, and preservatives to create a homogeneous formula. This formula can vary depending on the desired texture (lotion, cream, gel, spray, etc.) and the desired sun protection factor (SPF).
- Stabilization: Active ingredients can become unstable when exposed to light or heat. Therefore, stabilizers are often added to ensure that the sunscreen remains effective throughout the product's shelf life.
- Quality testing: Finished products undergo quality testing to ensure they meet the manufacturer's stated sunscreen standards. Stability testing verifies that the product maintains its effectiveness under different conditions.
