Many people tend to think that natural, handmade products cannot match the standards of professional ones. While we strive for effectiveness in our product development, safety remains our primary principle. For oil-based products, we have increased the proportion of antioxidants in our formulas. For water-containing products, we utilize a "preservative-free" system that combines "Caprylhydroxamic Acid" and "Caprylyl Glycol" derived from coconut oil, along with "Propanediol" and "1,2-Hexanediol" derived from corn sugar. This preservative-free system is not only currently adopted by professional market formulations, but it is also non-toxic to both the product and the skin, providing a milder and more reliable broad-spectrum antimicrobial preservative performance.

To ensure the effectiveness of our new "preservative-free" system, we submitted it to the SGS certification body for professional cosmetic preservative efficacy testing. The preservative system was tested according to the highest standard of the United States Pharmacopeia (USP) <51> "Antimicrobial Effectiveness Testing." This test evaluates antimicrobial efficacy against bacteria, yeast, and mold. The results confirm that our "preservative-free" system is capable of resisting contamination from common bacteria and mold, effectively inhibiting bacterial growth within the products.
