99% Sodium Sulphate Anhydrous Low Toxicity & High Safety Versatile Functional Performance

1. Product Overview

2. Key Features & Functions

• Stable Chemical Properties: It is chemically inert under normal temperature and pressure, not reacting with most oxidizing or reducing agents. It only decomposes above 884℃ to form sodium oxide (Na₂O) and sulfur trioxide (SO₃), ensuring stable performance in various industrial processes.
• Controllable Solubility: Its solubility in water increases significantly from 0℃ to 32.384℃, reaches a maximum, and then becomes almost independent of temperature above this point. This unique solubility characteristic makes it suitable for scenarios requiring precise concentration control, such as textile dyeing and chemical synthesis.
• Slight Hygroscopicity: It absorbs moisture slowly in humid air and may convert to decahydrate sodium sulfate (Glauber's salt) under high humidity conditions, but this process is reversible and does not affect its core performance when properly stored and dried.
• Low Toxicity & High Safety: It is generally non-toxic and classified as a non-hazardous substance in transportation. It has low corrosiveness to common industrial equipment, with only mild irritant effects on the eyes and skin upon prolonged contact, making it safe to handle with standard protective measures.
• Versatile Functional Performance: It acts as a filler, leveling agent, flux, and drying agent in different industries. It improves the flowability of powdered products, promotes uniform dyeing, reduces melting temperatures, and removes moisture efficiently, adapting to diverse industrial needs

4. Packaging & Storage

4.1 Packaging

• Standard Packaging: 25kg/50kg polypropylene (PP) woven bags with inner polyethylene (PE) liner, which is moisture-proof, tear-resistant, and dust-proof, effectively preventing moisture absorption and product leakage.
• Bulk Packaging: 1000kg/1200kg flexible intermediate bulk containers (FIBC, jumbo bags) with moisture barrier liner, suitable for large-scale industrial procurement and ocean transportation, improving loading and unloading efficiency.
• Custom Packaging: According to customer requirements, provide palletized, shrink-wrapped, or waterproof packaging to meet different transportation and storage needs, ensuring product integrity during long-distance shipping.

4.2 Storage

• Store in a dry, cool, well-ventilated warehouse, away from direct sunlight, moisture, and high-temperature environments (storage temperature recommended: 5-30℃) to prevent moisture absorption and caking.
• Keep separate from incompatible substances such as strong acids, aluminum, magnesium,  and avoid mixing with food, coal, cement, or other materials to prevent contamination.
• Seal the package tightly immediately after opening to reduce moisture absorption; the opened product should be used up as soon as possible to avoid caking affecting usability.
• When stacking, avoid excessive height (generally no more than 10 layers) to prevent bag rupture due to pressure; avoid contact with sharp objects to prevent packaging damage and product leakage.
• Empty containers should be properly treated as they may retain product residues; observe all safety precautions applicable to the product when handling empty bags.

5. Industrial Applications

• Detergent Industry: The largest application field. It serves as a filler and anti-caking agent in powdered detergents, improving the flowability of detergent formulations, preventing caking during storage, and enhancing the dispersion of active cleaning ingredients in water to boost decontamination efficiency.
• Textile Industry: Used as a leveling agent in textile dyeing. It reduces the negative charge on fiber surfaces, allowing dyes to penetrate evenly and effectively, ensuring uniform dyeing results. It also does not corrode stainless steel dyeing equipment, unlike conventional sodium chloride.
• Glass Industry: Acts as a fluxing agent, lowering the melting temperature of silica and other glass raw materials, reducing energy consumption. It also helps remove bubbles from molten glass, improving the transparency and quality of glass products.
• Chemical Industry: Used as a raw material for the production of sodium sulfide, sodium silicate, and other chemical products. It also serves as a drying agent for organic compounds, removing water more efficiently than other drying agents such as magnesium sulfate.
• Food Industry: Food-grade sodium sulphate anhydrous is used as a food additive, adjusting food taste and stability, and can also be used as a processing aid in food production (complies with standards such as China GB 1886.25-2020).
• Paper Industry: Used in the kraft pulping process. When heated with wood chips, it is reduced to sodium sulfide, which breaks the bonds in wood cellulose, softening wood chips and facilitating pulp formation.
• Other Applications: In the pharmaceutical industry, it can be used as a laxative; in water treatment, it is used for water softening and pH adjustment; it is also used in leather processing, mineral processing, and as a standard reagent in laboratory analysis.

6. Transportation Guidelines

• Sodium Sulphate Anhydrous is classified as a non-hazardous substance for transportation (no UN number required), complying with the transportation regulations of the country/region where it is shipped.
• Use covered, clean transport vehicles (such as closed trucks or container ships for ocean freight) to avoid sun exposure, rain, and moisture during transit, preventing product caking and packaging damage.
• Do not mix with strong acids, oxidants, foodstuffs, or other incompatible goods during transportation to avoid chemical reactions or contamination.
• Handle gently during loading and unloading, avoid violent collision, extrusion, and falling, to prevent bag rupture and product leakage; clean up spilled products promptly to avoid environmental contamination.
• The transport vehicles and packages should be clearly labeled with product information (name, purity, weight) and handling precautions (such as "Moisture-Proof", "Handle with Care").
• Drivers and handlers should wear basic protective equipment (gloves, masks) to avoid inhalation of dust or direct contact with the product for a long time.

7. Safety Notice

• Personal Protection: Wear dust masks, chemical-resistant gloves, and goggles when operating to avoid direct contact with the product and inhalation of dust.
• Skin Contact: Immediately rinse the affected area with plenty of clean water for 10-15 minutes; if irritation persists, seek medical attention promptly.
• Eye Contact: Immediately rinse with plenty of water or normal saline for at least 20 minutes, do not rub, and seek medical attention immediately if discomfort occurs.
• Inhalation: Move the inhaler to a well-ventilated area, rest, and keep the respiratory tract unobstructed; seek medical attention if coughing, chest tightness, or other discomfort occurs.
• Storage and Disposal: Keep out of reach of children and unauthorized personnel; dispose of waste products and packaging in accordance with local environmental protection regulations, do not discard them at will.
• Fire Fighting: It is non-flammable; in case of fire, use water, dry powder, or carbon dioxide fire extinguishers to put out the fire, and avoid splashing of burning materials causing secondary hazards.
