Hydroxyapatite is also explored as a food additive and in dental care products, such as toothpaste and mouthwash, for its remineralizing properties. In cosmetics, it is used for its ability to bind moisture and improve skin texture. The safety of hydroxyapatite in these applications is generally supported by its low solubility and lack of systemic absorption, but it remains essential to adhere to regulatory standards and perform safety assessments.
