Is there a difference between octyl oxime and octyl hydroxamic acid?

    Octyl hydroxamic acid is an ideal organic acid with excellent antibacterial and bacteriostatic properties at neutral pH value. It can be used in formulations without chemical preservatives. Octyl hydroxamic acid is the best bacteriostatic organic acid from acidic to neutral. It has highly efficient chelation, the active elements needed to inhibit mold and limit the environment required for microbial growth. Octyl hydroxamic acid and most of the raw materials have concurrent solubility, is not affected by the system of surfactant, protein and other raw materials, can be mixed with alcohols, dialcohols and other preservatives. It can be added at room temperature and high temperature. Widely used in gel, essence, lotion, cream, shampoo, shower dew and other skin care products.

    Octanooxime acid has the following properties:

    (1) Caprylamic Acid (OCyl oxime Acid)

    (2) white or quasi-white powder

    (3) Content ≥99%

    (4) Easily soluble in propylene glycol, glycerin, surfactant

    (5) Skin irritation: no irritation

    (6) Eye irritation: no irritation

    (7) Sensitization: non-skin sensitization.

    Characteristics of octanooxime acid

    Octyl oxime acid (CHA) has a strong inhibitory effect on fungi, and its antibacterial principle is as follows: CHA has highly selective chelation of Fe2+ and Fe3+. Mold growth is limited in iron-restricted environments. Iron is a key element for microbial growth, and microbial release chelators (siderophores) capture and convert Fe3+ from the environment. CHA chelates Fe3+ with a high stability constant, which can prevent mold from obtaining iron, and it is still effective when pH value is neutral, so it is an ideal organic acid for bacteriostasis. CHA also has short-chain activity and, like octanediol, it also has an optimal carbon chain length that promotes structural degradation of cell membranes.

    As an organic acid, CHA can inhibit the growth of mold only when it is dispersed in the product in an undissociated state. Therefore, CHA can only exert antibacterial effect in neutral or slightly acidic environment. In the production of CHA, deionized water should be used, and appropriate chelating agent, such as EDTA-2NA, should be added to avoid contact with copper ions and iron ions, so as to overcome possible discoloration, which should be paid special attention in use.

    Octyl oxime acid and octyl hydroxamic acid are Chinese synonyms of N-hydroxyl n-octyl amide, cas number is the same, is the same compound.
