Cream of tartar

Potassium bitartrate, also known as potassium dihydrogen tartrate, is a white crystalline powder widely used in food, pharmaceutical, and chemical industries. In the food industry, it serves as a leavening agent and acidulant for baked goods and beverage preparation; in pharmaceuticals, it functions as a laxative component; and in chemicals, it is employed in electroplating and as a pharmaceutical intermediate.
As a specialized supplier, we possess distinct core advantages.Strict quality control ensures purity exceeding 99% with zero heavy metal residues.Stable production capacity enables rapid fulfillment of bulk orders.Offering diverse packaging options including 25kg bags and ton bags, with custom repackaging available. Post-sales response time guaranteed within 2 hours.

Basic Properties


1. Physical Properties

- Appearance: White crystalline powder or colorless transparent crystals, odorless, with a slightly sour taste.

- Solubility: Soluble in hot water, poorly soluble in cold water and ethanol. Solubility in water at 20°C is approximately 0.83 g/100 mL.

Density is approximately 1.98 g/cm³, with a melting point of 267°C. Decomposition occurs above this temperature.

2. Chemical Properties

- Molecular formula: C₄H₅KO₆; molecular weight: 188.18. Classified as an acidic salt; aqueous solution exhibits weak acidity (pH ~3.5).

- Decomposes readily upon heating, yielding potassium tartrate, tartaric acid, carbon dioxide, and water.

- Reacts with alkalis to form tartrates; e.g., reacts with potassium hydroxide to produce potassium tartrate.

3. Safety

- As a food additive, complies with GB 1886.234-2016 standards and is harmless to humans when used within specified limits.

- Non-corrosive and non-explosive. Store in a sealed container in a cool, dry place to prevent moisture absorption and caking.

Main Applications


Potassium bitartrate finds its primary applications in three key sectors: food, pharmaceuticals, and industry, all directly linked to its acidic and stabilizing properties.

1. Food Industry: Core Application Areas

- As a leavening agent, it is blended with baking soda in baking applications (e.g., cakes, cookies), releasing carbon dioxide upon heating to create a light, fluffy texture.

- As an acidulant, it adjusts the acidity of beverages and jams, enhancing flavor complexity. It is also used in winemaking to produce tartaric acid.

- As a stabilizer, it prevents protein coagulation in dairy products (e.g., cheese), improving product texture.

2. Pharmaceutical Sector: Functional Applications

- As a laxative component, it stimulates intestinal peristalsis to relieve constipation, commonly found in compound formulations.

- As a pharmaceutical excipient, it adjusts the pH of drug formulations or acts as a tablet disintegrant to facilitate rapid dissolution within the body.

3. Industrial Applications: Auxiliary Uses

- Used in electroplating as an additive to improve the uniformity and luster of metal coatings.

- Serves as a chemical intermediate for synthesizing tartrate products or adjusting the pH of tanning solutions in leather processing.

Safety Precautions


1. Safety Precautions

When used as a food additive, strict adherence to the maximum permitted levels specified in GB 1886.234-2016 is mandatory; do not exceed these limits.

Industrial-grade products are strictly prohibited for food applications. Store them separately from food-grade products to prevent cross-contamination.

Wear dust masks and gloves during handling to avoid inhalation of powder or prolonged skin contact, which may cause mild irritation.

2. Storage Safety

Store in a dry, cool, well-ventilated warehouse away from water sources and humid environments to prevent moisture absorption and caking.

Avoid co-storage with strong alkalis, strong oxidizing agents, or other chemicals to prevent chemical reactions that could alter product properties.

Packaging must be sealed intact with clear labels indicating product name, specifications, and the “Non-Edible” (Industrial Grade) designation.

3. Emergency Response

If powder is accidentally inhaled, immediately move to fresh air and seek medical attention if necessary.

If powder contacts skin or eyes, flush with copious amounts of running water for at least 15 minutes. Seek medical care if symptoms persist.

If ingested, induce vomiting by drinking ample warm water immediately. Take the product label to the hospital.
