Given that facial base makeup products involve extensive direct skin contact and are used frequently, their safety controls are subject to stricter standards than those for ordinary color cosmetics. Primary attention must be focused on three key areas: raw material safety, formulation irritancy, and usage risks.
Raw Material Compliance and Purity Control
Powder ingredients-such as titanium dioxide and iron oxides-must adhere to cosmetic-grade standards, with heavy metal content strictly controlled within safe limits. Oils, silicones, and emulsifiers should be selected based on their low-allergen and low-irritancy profiles, avoiding the use of industrial-grade or unpurified ingredients. Furthermore, all raw materials must undergo microbiological testing to prevent potential contaminants from entering the product system.
Formulation Irritancy and Skin Compatibility
Base makeup products typically contain preservatives, fragrances, or functional ingredients, all of which may trigger sensitive reactions. Consequently, their inclusion levels must be carefully controlled, and rigorous skin irritation testing must be conducted. For products designed for sensitive skin, the use of fragrances and potentially allergenic preservative systems should be minimized; instead, mild emulsifiers and stabilization systems should be selected to mitigate the risk of irritation.
Usage Safety and Product Stability
Base makeup products must successfully pass heat resistance, cold resistance, centrifugation, and accelerated aging tests to ensure they do not separate, degrade, or develop off-odors. During actual use, prolonged exposure to air-which can lead to contamination-should be avoided; it is recommended to adhere to a specific usage timeframe following the product's opening. Overall, the key to ensuring the safety of facial base makeup lies in the harmonious integration of three elements: "compliant raw materials," "gentle formulations," and "stable product systems."
