Preservatives for Natural Cosmetic

SJ Chemical\'s Preservatives for Natural Cosmetic line brings nature-derived preservation to the clean beauty era.
Its flagship, SJC-GUARD GREEN22, is a 100% natural polylysine preservative fermented from Streptomyces albulus, giving broad-spectrum protection at very low dosages.
Its core ingredient, ε-polylysine, is approved as a food additive in the US (FDA GRAS), Japan, Korea and China, a food-grade safety profile that gives formulators and consumers real confidence.
It also qualifies for Korea's Type 1 detergents for fruits, vegetables and dishes, where common preservatives such as CMIT/MIT and phenoxyethanol are not allowed. That takes it beyond cosmetics into kitchen and home care.
Unlike conventional natural preservatives that only work in acidic formulas, it stays effective at neutral pH 5–8 and remains stable at 80–120°C, fitting both mild formulations and heat processing.
SJC-Lacto Preservative, made from Lactobacillus Ferment, is a gentle, water-soluble option that fits everything from skincare to BB creams.
The SJP series of natural-origin diol and glycol boosters (Pentylene Glycol, 1,2-Hexanediol, Butanediol, Propanediol) adds moisture while strengthening preservation. Used together with the preservatives, they work in synergy, so brands can use less preservative and keep formulas gentle on skin.
For lip and oral care, baby products and inner beauty, where products touch the mouth or may be swallowed, SJ Chemical offers something few can match: "Food-grade Clean Preservation."
Built to meet COSMOS, REACH and HALAL standards, the range lets brands tell a confident natural, fermented, bio-based story.
