1. Personal Care and Cosmetics Industry
This is the main application area for caprylohydroxamic acid, primarily utilizing its chelating and preservative-enhancing functions.

• As a multi-functional chelating agent:
It effectively integrates metal ions (such as iron, copper, and aluminum ions) introduced during formulation and production, protecting product stability, reducing potential harm to the skin, and serving as an environmentally friendly alternative to traditional chelating agents (such as EDTA).

• As a preservative enhancer/”preservative-free” preservative:
By chelating iron ions and other elements necessary for microbial growth, it indirectly inhibits their growth (with particularly effective results against mold), thus assisting or partially replacing traditional preservatives. Its optimal pH range is acidic to neutral (pH 3-7 or 4-7.5).

• As a tyrosinase inhibitor:
It can integrate the copper ions required by tyrosinase in the melanin production process, thus playing an auxiliary whitening role in formulations.

• Application product types:
Widely used in various personal care and skincare products such as face creams, lotions, shower gels, shampoos, and eye and lip products.

2. Industrial Field
• As a metal ore flotation collector:
Its sodium salt form (sodium caprylohydroxamate) is an important industrial raw material, mainly used in the flotation separation and extraction of metal oxide ores such as rare earth ores, copper oxide ores, hematite, and scheelite. This is another major industrial application.

• As an industrial anti-mold and preservative agent:
It can be used in paints, coatings, adhesives, textiles, and industrial water treatment to prevent microbial growth and metal corrosion.

3. Environmental Protection and Scientific Research Fields
• Environmental remediation:
Utilizing its strong chelating properties, it can be used to treat wastewater containing heavy metal ions and adsorb and recover rare earth elements from aqueous solutions.

• Biochemical and pharmaceutical research:
Used as a urease inhibitor in related biochemical research; its structure is also being explored as a drug lead compound, for example, in research aimed at lowering blood ammonia levels.

• Polymer chemistry:
It can be used as a functional monomer to improve the performance of polymers such as coatings and adhesives.
