❓ Frequently Asked Questions (FAQ)
Q What is nano-hydroxyapatite and how does it differ from regular hydroxyapatite?
Nano-hydroxyapatite (nHA) is a nanoscale form of hydroxyapatite with particle sizes typically ranging from 20 nm to 60 nm. Compared to conventional hydroxyapatite, it has a significantly larger specific surface area, higher reactivity, and superior biocompatibility — more closely mimicking the mineral composition of natural human bone and tooth enamel.
Q Is nano-hydroxyapatite safe for use in toothpaste and oral care products?
Yes. Nano-hydroxyapatite is non-toxic, non-irritating, and biocompatible. It is widely used as a fluoride-free alternative in toothpaste and mouthwash. It is particularly suitable for children and individuals with sensitive teeth, as it helps repair enamel, reduce sensitivity, and prevent cavities without the risks associated with fluoride overexposure.
Q What particle sizes are available and how does particle size affect performance?
The product is available in three particle sizes: 20 nm, 40 nm, and 60 nm. Smaller particle sizes generally offer higher surface area and stronger adsorption capacity, which is beneficial for biomedical and water treatment applications. Larger particles may be preferred for specific structural or carrier applications. The optimal size depends on the intended use.
Q Can nano-hydroxyapatite be used for heavy metal removal in water treatment?
Yes. Nano-hydroxyapatite exhibits strong adsorption capacity for heavy metal ions including lead (Pb), cadmium (Cd), copper (Cu), and nickel (Ni), as well as fluoride ions. It is used in both industrial wastewater deep treatment and drinking water purification processes, offering an effective and environmentally friendly solution.
Q What are the storage requirements for nano-hydroxyapatite powder?
Nano-hydroxyapatite powder should be stored in a sealed container in a dry, cool place, away from moisture and direct sunlight. Proper storage prevents clumping, contamination, and degradation of product quality. Available packaging options include 1 kg/bag, 5 kg/bag, and 25 kg/drum to suit various usage scales.
Q What industries and sectors commonly use nano-hydroxyapatite?
Nano-hydroxyapatite is used across a wide range of industries including oral care (toothpaste, mouthwash), biomedical engineering (bone repair, dental implants, drug delivery), environmental protection (water purification), chemical and biochemical separation (chromatography, enzyme carriers), food manufacturing (calcium fortifier), cosmetics, and advanced materials such as ceramics and bio-glass.
