What Is Caprylhydroxamic acid?

Caprylyl hydroxamic acid is an ideal organic acid for antibacterial. It has high-efficiency and selective chelation ability for ferrous ions and ferric ions, and the growth of mold is limited in the environment with limited iron ions. At the same time, it has the optimal carbon chain length that can promote the degradation of cell membrane structure. Therefore, it has strong antibacterial ability and is a new substitute for preservatives. Octyl hydroxamic acid is used to prepare octyl hydroxamic acid.
It has excellent antibacterial and antibacterial properties at neutral pH, and can be used in formulation systems without chemical preservatives. It is an organic acid that maintains a non-ionized state from acidity to neutrality, and is the best antibacterial organic acid. It has high-efficiency chelation, inhibits the active elements required by mold, and limits the environment required for microbial growth. It is compatible with most raw materials and is not affected by surfactants, proteins and other raw materials in the system. It can be compounded with alcohols, glycols and other preservatives. Can be added at room temperature and high temperature environment. Widely used in gel, essence, lotion, cream, shampoo, shower gel and other skin care and hair care products.

What are the benefits?

Antiseptic and antibacterial effect
It is highly effective in inhibiting mold, and the minimum inhibitory concentration against Aspergillus niger is 0.078%. It has high safety and is widely used in Europe, the United States, Japan, and South Korea. As an organic acid, it can attack mold only when it is dispersed in the organism in an undissociated state. Therefore, caprylyl hydroxamic acid remains in an undissociated state from acidity to neutrality, and can effectively inhibit bacteria in this environment. Other preservative alternatives are not very effective in this environment

Integrated efficacy
It has efficient and selective chelation for Fe2+ and Fe3+. In iron ion-limited environment, the growth of mold is limited. Iron is a key element for microbial growth. Microorganisms release chelating agents (Siderophores), capture Fe3+ from the environment and convert it into Fe2+, and CHA has a high stability constant for chelating Fe3+, which can prevent mold from obtaining iron. It has high-efficiency chelation, inhibits the active elements required by mold, and limits the environment required for microbial growth.

Short chain table activity function
Caprylyl hydroxamic acid, like caprylyl glycol, also has a carbon chain length (C8) that promotes the degradation of cell membrane structures. The microbial inhibition efficiency is related to the size of the alkyl carbon chain and the position of the hydroxyl group. Microorganisms with medium carbon chain length and ortho-hydroxy groups have better inhibitory effect. By interfering with the physiological environment of the inhibitory cell membrane, the short-chain structure selectively gathers on the water-oil interface in the oil-in-water emulsion system, making the food source of microorganisms in this area unfavorable to the growth of microorganisms and inhibiting the growth of microorganisms.

Application in cosmetics

In cosmetics and skin care products, it is mainly used as an antibacterial agent and a chelating agent. It is relatively safe and can be used with confidence. It generally has no effect on pregnant women and has no acne-causing properties. Caprylyl hydroxamic acid is an ideal organic acid for antibacterial. CHA has a high stability constant for chelating Fe3+, which can prevent mold from obtaining iron, and it is still effective when the pH value is neutral, so it is an ideal organic acid for antibacterial.

In cosmetics, it can be used for anti-aging, moisturizing, anti-inflammatory, anti-oxidation, anti-acne, anti-wrinkle and other functions. It can help improve the elasticity of the skin, improve the fine lines of the skin, reduce wrinkles, improve the firmness of the skin, improve the pigmentation of the skin, improve the inflammation state of the skin, improve the antioxidant capacity of the skin, and improve the anti-acne ability of the skin , Improve the anti-aging ability of the skin, improve the anti-inflammatory ability of the skin, improve the antibacterial ability of the skin, improve the anti-sensitivity ability of the skin, etc.

Why do skin care products add preservatives

Preservatives are ingredients intended to inhibit the growth of microorganisms in cosmetics. Various ingredients in skin care products will provide a good growth environment for microorganisms. If no preservatives are added, microorganisms will turn skin care products into their culture medium and grow and multiply rapidly. If cosmetics are contaminated by microorganisms, there will be two effects:

1. Affect product quality: mildew, turbidity, demulsification, PH value change, foaming, odor change, etc.

2. Affect consumers' health: changes in skin microecology, allergies, atopic dermatitis, skin infections, meningitis, etc.
