Common Name: Citric acidChemical Name: 2-hydroxypropane-1,2,3-tricarboxylic acidOther Name: Anhydrous citric acid

Name

C6H8O7

STRUCTURAL FORMULA

Citric Acid:

To balance the pH levels

153 °C (307.4F, 426 K)

PROPERTIES

Physical State at Room Temp.

Melting Point

Boiling Point

Density/ Specific Gravity

Solubility

White or colorless, odorless crystalline powder. It can exist either in an anhydrous (water-free) form, or as a monohydrate that contains one water molecule for every molecule of citric acid.

1.665 g/mL at 20 °C

Decomposes at 175°C (448 K)

Water: 1174g/L at 10°C, 1809g/L at 30°C, 3825g/L at 80°C Also Soluble: - ethanol (alcohol): 62 g/100 g (25 °C), - diethyl ether: 1.05 g/100 g (25 °C)

ACUTE TOXICITY

FLAMMABILITY

May be combustible at high temperature Limits: Lower: 0.28 kg/m3 (Dust) Upper: 2.29 kg/m3 (Dust)

REACTIVITY

- Reacts with oxidizing agents, bases, reducing agents and metal nitrates - Reactions with metal nitrates are potentially explosive. - Heating to the point of decomposition causes emission of acrid smoke and fumes

CORROSIVENESS

ACUTE TOXICITY

Mutagenicity/Teratogenicity/Carcinogenicity

Citric acid is not a CMR (carcinogenic, mutagenic, repro- toxic) substance nor an endocrine disrupting substance.

Isolation

The pioneering Swedish–German chemist Carl Wilhelm Scheele who precipitated it as calcium citrate by adding calcium hydroxide to lemon juice (1784)

Industrial Uses

Industrial Uses

Cleaning Agent Citric acid is one of the chelating agents. With the help of citric acid, limescale from evaporators and boilers is removed. It is used in soaps and laundry detergents since water is softened by the acid. Household cleaners used in the kitchen and bathroom also contain some amount of citric acid. It is not only used as a cleaner but also as a deodorizer

Cosmetics Citric acid helps in the removal of dead skin, so can be used for home masks. Improves skin tone and skin growth, reducing wrinkles, acne scars etc. Citric acid is commonly used as an ingredient to balance the pH levels in cosmetic products It also can be found in hand soap, body wash, nail polish, face cleansers, shampoos and some other items

Fun Facts

Citric Acid and ascorbic acid are both naturally occurring in citrus fruits, but there is actually NO vitamin C in them

It helps your body detox! Citric acid increases the body's cellular energy production so that your body can cleanse and detoxify!

Citric acid has been shown to help speed up metabolism and aid in weight loss
