New eco-friendly, germicidal and preservative agents for eye and lip cosmetics
Cosmetics contain a large amount of nutrients, providing suitable conditions for the growth and reproduction of microorganisms. If the products are contaminated by microorganisms, it is likely that the microorganisms will multiply in large numbers. Therefore, it is necessary to add a certain amount of preservatives to cosmetics to prevent them from deteriorating and spoiling during their shelf life and during consumer use.
Formaldehyde is a restricted substance stipulated in the "Cosmetics Safety Technical Specifications" (2015 Edition). When used as a preservative in cosmetics, its total amount should not exceed 0.2% by mass fraction (calculated based on free formaldehyde).
The amount of formaldehyde released by formaldehyde-releasing preservatives is related to the cosmetic base and environmental conditions. The control standards are strict and the process is complex. Microorganisms in cosmetics have certain adaptability to preservatives, and long-term use may pose health risks. New antibacterial cosmetics require more efficient and safe preservative solutions.
Given the special application areas and high usage risks of eye and lip cosmetics, the relevant national regulations have set stricter quality standards for these cosmetics. The regulations require that cosmetic manufacturers devote more effort and resources to research and development, production, and quality control to ensure that the products meet the high-quality standards.
According to the "Cosmetics Safety Technical Specifications (2015 Edition)", the requirements for the total number of colonies in Chinese cosmetics are as follows: for eye cosmetics, lip cosmetics and children's cosmetics, it should be ≤ 500 CFU/g or CFU/ml; for other cosmetics, it should be ≤ 1000 CFU/g or CFU/ml; the total number of molds and yeasts should be ≤ 100 CFU/g or CFU/ml.
Dalian Tianwei Chemical Bactericidal and Antifungal Preservatives adopt a unique composite hydrogen peroxide formula, which possesses strong bactericidal capabilities. It can damage the cell walls and cell membranes of microorganisms, causing them to lose their activity and quickly kill various microorganisms without causing the microorganisms to adapt. It is safe and environmentally friendly, without irritation, color or odor, and without teratogenic effects. It meets the high safety requirements of eye and lip cosmetics.
