How are preservatives in cosmetics protected?
Preservatives in cosmetics are various preparations for killing or inhibiting microorganisms and are protective agents for maintaining the quality of cosmetics. In general, a preservative acts to disrupt cell division and inhibit bacterial growth and reproduction by acting on the cell membrane of a microorganism, cell walls, and enzymes required for growth and metabolism.
Preservatives in cosmetics have the following three characteristics:
1 full safety, as far as possible non-toxic, non-irritating.
2 Extensive effectiveness, ability to kill bacteria, mold, yeast, etc.
3 The long-term stability and good compatibility with the system cannot affect other components of the system.
