Stored in a ventilated and dry warehouse.
Sodium stearate should be stored properly to maintain its quality and effectiveness. Here are some storage guidelines:
1. Container: Store sodium stearate in a tightly sealed container to protect it from moisture and contamination.
2. Temperature: Please store in a cool and dry place away from direct sunlight and heat sources. The ideal storage temperature is usually between 15°C and 30°C (59°F and 86°F).
3. Humidity: Because sodium stearate absorbs moisture, it must be stored in a low humidity environment to prevent clumping or degradation.
4. Label: Make sure containers are clearly labeled with contents and any relevant safety information.
5. SAFETY PRECAUTIONS: Follow any specific safety guidelines provided by the manufacturer, including the use of personal protective equipment when necessary.
Sodium stearate is generally considered to have low toxicity and is not classified as a hazardous material under normal conditions of handling and use. However, like any chemical, it may present some risks if not handled properly. Here are some key points to consider:
1. SKIN AND EYE IRRITATION: Contact with sodium stearate may cause mild irritation to the skin and eyes. It is recommended to wear gloves and goggles when handling large quantities or concentrated forms of sodium stearate.
2. Inhalation: Inhalation of dust or aerosol may cause respiratory irritation. It is recommended to use in a well-ventilated area, or if dust is generated, please take appropriate respiratory protection measures.
3. Ingestion: Although sodium stearate is used in food and cosmetics, ingesting large amounts can cause gastrointestinal discomfort.
4. Environmental impact: Sodium stearate is biodegradable, but it is still necessary to avoid discharging large amounts of sodium stearate into the environment.
