Ethylenediaminetetraacetic Acid (EDTA)

Ethylenediaminetetraacetic Acid (EDTA), also known as edetic acid, is a white, odorless crystalline powder widely used as a chelating agent in various industries. With the chemical formula C₁₀H₁₆O₈N₂ and a molecular weight of 292.25, EDTA binds to metal ions such as Fe²⁺/Fe³⁺ and Ca²⁺, forming water-soluble complexes even at neutral pH. This property makes it essential in dissolving metal-containing scales and delivering iron ions in chemical processing, agriculture, water treatment, and hydroponics. In the pulp and paper industry, EDTA inhibits metal ions, especially Mn²⁺, from degrading hydrogen peroxide during bleaching. It also stabilizes colors in textiles by preventing metal ion impurities from altering dyed products. EDTA serves as an anticoagulant in blood analysis, preserving samples by chelating calcium ions. In personal care products like shampoos and cleaners, EDTA salts improve stability by sequestering metal ions. Additionally, EDTA acts as a preservative in foods, preventing catalytic oxidative discoloration caused by metal ions. Its versatility makes it indispensable in industrial, agricultural, and consumer applications.

Tartrazine

Tartrazine (also known as FD&C Yellow 5, Acid Yellow 23, and Food Yellow 4) is a synthetic lemon yellow azo dye primarily used as a food coloring. It may also be referenced as E number E102, C.I. 19140.
In addition to being a colorant in food, drugs and cosmetics, it can be used to dye silk and wool. It serves as a dye for wool and silks, a colorant in food, drugs and cosmetics.

Many foods contain tartrazine in varying proportions, depending on the manufacturer or person preparing the food. When in food, tartrazine is typically labelled as "color", "tartrazine", or "E102", depending on the jurisdiction, and the applicable labeling laws (see Regulation below).

Products containing tartrazine commonly include processed commercial foods that have an artificial yellow or green color, or that consumers expect to be brown or creamy looking. It has been frequently used in the bright yellow coloring of imitation lemon filling in baked goods.

Foods containing Tartrazine may include ice cream, ice pops, popsicles, candy, gummy bears, cotton candy, instant puddings, gelatin, cake mixes, pastries, custard powder, marzipan, biscuits, and cookies.
Beverages containing Tartrazine may include soft drinks, energy and sports drinks, powdered drink mixes, fruit cordials, and flavored/mixed alcoholic beverages.
Snacks containing Tartrazine may include flavored corn chip, chewing gum, popcorn, and potato chips.
Condiments and spreads containing Tartrazine may include jam, jelly, marmalade, mustard, horseradish, pickles, and processed sauces.

A number of personal care and cosmetics products may contain tartrazine, usually labelled as CI 19140 or FD&C Yellow 5, including:

Liquid and bar soaps, green hand sanitizer, moisturizers and lotions, mouth washes, perfumes, toothpastes, shampoos, conditioners, eyeshadow, blush, face powder and foundation, lipstick, nail polish, nail polish remover, temporary tattoos, and tanning lotions.

In most jurisdictions, presence of Tartrazine must be declared on the product label if used in food, medicine or personal care products.

Some people may have sensitivity to Tartrazine.
According to the FDA, tartrazine causes hives in fewer than 1 in 10,000 people, or 0.01%. Symptoms may appear after a few minutes up to 14 hours after exposure.
For additional information, please see Code of Federal Regulations #21, Parts 1-99.
