Potassium bitartrate

Potassium bitartrate (CAS 868-14-4), commercially recognized as cream of tartar and listed as E336, is a naturally derived acid salt produced as a byproduct of wine fermentation.

Where is Potassium bitartrate used?

• Food and personal care manufacturing: leavening acid, buffering agent, and stabilizer
• Baking: activates baking soda for controlled leavening
• Cakes, cookies, and baked mixes: stabilizes whipped egg whites and meringues against collapse
• Confectionery: prevents sugar crystallization in candies, frostings, and syrups, improving texture consistency
• Processed vegetables: pH buffer and tartrate source, retaining color and firmness during thermal treatment
• In dental powders and skin-brightening preparations it acts as a mild acidulant and buffering agent.

Commercial specifications

• Food-grade material conforming to FCC and E336 specifications
• High purity USP and BP grades for pharmaceutical and personal care applications
• Bulk supply typical for industrial food processing; smaller packaging for specialty markets
