The antibacterial properties of octanoyl hydroxamic acid can be traced back to the invention patent CN 1029206 12A of Xu Jinrong 20 12. This patent discloses a broad-spectrum antibacterial cosmetic preservative, in which the content of octanoyl hydroxamic acid is 8- 12%, which can effectively inhibit gram-negative bacteria, positive bacteria, molds and yeasts, and the antibacterial performance is not affected by cosmetics. In recent years, it has been widely used in cosmetics because of its antibacterial properties.
Extended data:
Octyl hydroxamic acid has a strong chelating ability to metal ions, so it is often used as a collector in the field of mineral flotation, and also found to be added to animal feed as a growth promoter.
Octyl hydroxamic acid is not included in the list of preservatives in the Technical Specification for Cosmetic Safety (20 15), but because of its good synergistic antiseptic performance, some cosmetic manufacturers add it to cosmetics to play the role of preservative, and declare that their products do not contain preservatives, so as to achieve the effect of promoting "no addition".
