Product Overview
Sodium Bicarbonate, commonly known as baking soda, is a white, odorless, crystalline powder with the chemical formula NaHCO3. It is produced through the Solvay process or through the mining and purification of natural trona ore (sodium sesquicarbonate). The INCI name is Sodium Bicarbonate, and it carries a CAS number of 144-55-8. The USP (United States Pharmacopeia) and Kosher certifications designate this grade as meeting the highest purity standards required for pharmaceutical, food, and personal care manufacturing applications.
Sodium Bicarbonate is one of the most widely used and chemically versatile ingredient compounds across industry. Its mild alkalinity (pH approximately 8.3 in aqueous solution), excellent water solubility, carbon dioxide-releasing reactivity with acids, natural odour-neutralizing capability, and gentle abrasive properties collectively make it an indispensable ingredient across personal care, food and beverage, pharmaceutical, cleaning, pet care, industrial, and craft manufacturing sectors. It is GRAS-classified by the FDA, Kosher certified, and approved internationally across all of its primary application industries.

Frequently Asked Questions
Q1: Which industries use Sodium Bicarbonate USP/Kosher?
Sodium Bicarbonate is one of the most broadly applicable ingredients at EZ Elements, used across seven industries: Personal Care (bath bombs, deodorants, toothpaste, scrubs), Food and Beverages (leavening, pH control, vegetable blanching, meat processing), Pharmaceutical (antacids, alkalinizing agents, tablet excipient), Cleaning and Sanitation (all-purpose cleaner, laundry booster, deodorizer), Pet Care (dry shampoo, litter deodorizer, aquarium pH buffer), Industrial (fire suppression, flue gas treatment, polymer blowing agent, water treatment), and Components (bath bomb crafting kits, baking kits, educational science experiments). Its versatility across all these sectors reflects its unique combination of mild alkalinity, CO2 reactivity, odour neutralization, and abrasive properties.
Q2: What is the difference between USP grade Sodium Bicarbonate and regular baking soda?
Regular baking soda (food grade) meets FDA food-grade standards and is suitable for cooking, baking, and general household use. USP grade Sodium Bicarbonate meets the stricter purity specifications of the United States Pharmacopeia, including tighter controls on assay, heavy metals, chloride, sulfate, and loss on drying. USP grade is required for pharmaceutical manufacturing and is also the preferred grade for personal care and cosmetic formulations where the highest ingredient quality and regulatory documentation are expected. The Kosher certification adds a further layer of compliance for manufacturers serving markets where Kosher-certified ingredients are required.
Q3: How does Sodium Bicarbonate work in bath bombs?
In bath bomb formulations, Sodium Bicarbonate is combined with citric acid in a dry mixture. When the bath bomb is dropped into water, the water triggers a rapid acid-base reaction between the sodium bicarbonate and citric acid, producing carbon dioxide gas. This CO2 release creates the characteristic fizzing and effervescent effect. The typical ratio is approximately 2 parts Sodium Bicarbonate to 1-part citric acid by weight. Additional ingredients such as carrier oils, fragrance, color, and skin-conditioning actives are incorporated into the base to create a complete bath bomb formulation.
Q4: Is Sodium Bicarbonate safe for use on pets?
Yes, in topical pet care applications. Sodium Bicarbonate is widely used in dry pet shampoos, grooming deodorizers, and litter box treatments for its safe, non-toxic odor-neutralizing properties. It is applied externally and brushed or wiped away rather than left on the skin in large amounts. It should not be ingested by animals in significant quantities. For aquarium use, it is a recognized and safe pH buffering agent for freshwater fish tanks when used at appropriate concentrations.
Q5: Can Sodium Bicarbonate be used as a natural deodorant ingredient?
Yes. Sodium Bicarbonate is one of the most commonly used active ingredients in natural deodorant formulations. It functions by neutralizing the acidic and alkaline compounds produced by odor-causing bacteria on the skin, rather than masking odor with fragrance. It is typically used at 5% to 20% in natural deodorant sticks, creams, and powders. However, some individuals with sensitive skin may experience irritation at higher concentrations due to the mild alkalinity of sodium bicarbonate; formulators often reduce the concentration or combine it with skin-soothing ingredients for sensitive-skin deodorant products.
