Synthetic biology offers notable advantages in S-Proxylane production: microbial fermentation or plant cell culture eliminates high-pollution chemical synthesis and resource-intensive plant extraction, reducing costs by over 40% and shortening production cycles to 7-10 days (vs. 30+ days traditionally). Biosynthesized S-Proxylane features ≥99.5% purity with superior structural uniformity, surpassing chemical synthesis (92%-95%) and avoiding organic solvent residues (e.g., methanol ≤0.3%). Quality-wise, synthetic products meet stricter standards, including lower heavy metals (lead ≤1mg/kg, arsenic ≤1mg/kg) and microbial limits (total colonies ≤100CFU/g), complying with EU EC 1223/2009 cosmetic regulations and ensuring stable formulation in high-end skincare.
