FAQ (Frequently Asked Questions)
1. What is FC-NaSnO?
FC-NaSnO is a high-purity form of Sodium Stannate (Na₂SnO₃), adapted for specialized applications in personal care products. Known for its stabilizing and chelating properties, FC-NaSnO is used in formulations that require enhanced product stability, clarity, and metal ion control. It also supports preservative systems and may contribute to the antioxidant capacity in skin and hair care products.
2. What is the CAS Number and INCI Name of FC-NaSnO?
CAS Number: 12058-66-1
INCI Name: Sodium Stannate
3. What are the benefits of using FC-NaSnO in personal care products?
Chelating Agent: Binds and neutralizes metal ions that may destabilize formulations or cause discoloration.
Product Stabilization: Helps maintain clarity and shelf stability in liquid or gel-based products.
Preservative Support: Enhances the efficacy of certain preservative systems by reducing interference from metal ions.
Antioxidant Properties: Offers minor antioxidant support by preventing oxidative degradation.
pH Control: Can assist in buffering formulations to desired pH levels.
4. What are the common applications of FC-NaSnO in personal care?
Hair Dyes and Colorants: Improves color stability and prevents degradation caused by metal contaminants.
Skin Care Serums and Creams: Enhances clarity and extends shelf life by reducing oxidation.
Facial Cleansers: Maintains product transparency and stability.
Toothpastes and Oral Care Products: Sometimes used in specialized formulations for stability and remineralization support.
Anti-aging Products: Helps preserve formulation integrity and active ingredient performance.
5. Is FC-NaSnO safe for use in personal care products?
Yes, FC-NaSnO is generally considered safe when used within recommended concentrations in cosmetic formulations. It is important to follow regulatory guidelines and ensure proper formulation to prevent excessive exposure, particularly in leave-on products.
6. Can FC-NaSnO cause skin irritation?
FC-NaSnO is typically non-irritating when used in low concentrations. However, like all chemical ingredients, it should be formulated appropriately and tested for dermal compatibility. Patch testing is recommended for new product development, especially for leave-on applications or sensitive skin formulations.
