In the context of changing regulations and consumer panic, the development of new low-toxic preservative systems, "no added" preservatives and natural preservatives has become an important way for sustainable development. Ethylhexyl glycerin is a representative variety of important "no added" preservatives and is a globally recognized multifunctional cosmetic additive. Ethylhexyl glycerol and preservative-enriched substances have been studied and applied for synergies. There have been many domestic and international professional preservative manufacturers and well-known cosmetic production companies applying for multiple patents, some of which are compatible with traditional preservatives. More is to form a "no-add" anti-corrosion system with polyol.
