Citric acid is an alpha hydroxy acid used in personal care products
to adjust the acidity or promote skin peeling and re-growth in the
case of anti-aging products. Citric acid is naturally found in
citric fruits and juices, providing the characteristic acidic

3 . Usage
Citric acid can be added to ice cream as an emulsifying agent to
keep fats from separating, to caramel to prevent sucrose
crystallization, or in recipes in place of fresh lemon juice.
Citric acid is used with sodium bicarbonate in a wide range of
effervescent formulae, both for ingestion (e.g., powders and
tablets) and for personal care (e.g., bath salts, bath bombs, and
cleaning of grease). Citric acid is also often used in cleaning
products and sodas or fizzy drinks.
Citric acid sold in a dry powdered form is commonly sold in markets
and groceries as "sour salt", due to its physical resemblance to
table salt. It has use in culinary applications where an acid is
needed for either its chemical properties or for its sour flavor,
but a dry ingredient is needed and additional flavors are unwanted
(e.g., instead of vinegar or lemon juice).
- Cleaning and chelating agent
Citric acid is an excellent chelating agent, binding metals. It is
used to remove limescale from boilers and evaporators. It can be
used to soften water, which makes it useful in soaps and laundry
detergents. By chelating the metals in hard water, it lets these
cleaners produce foam and work better without need for water
softening. Citric acid is the active ingredient in some bathroom
and kitchen cleaning solutions. A solution with a 6% concentration
of citric acid will remove hard water stains from glass without
scrubbing. In the industry, it is used to dissolve rust from steel.
Citric acid can be used in shampoo to wash out wax and coloring
from the hair.
Illustrative of its chelating abilities, citric acid was the first
successful eluant used for total ion-exchange separation of the
lanthanides, during the Manhattan Project in the 1940s. In the
1950s, it was replaced by the far more efficient EDTA. It can be
used to substantially slow setting of Portland cement.
- Cosmetics and pharmaceuticals
Citric acid is widely used as a pH adjusting agent in creams and
gels of all kinds. In this role, it is classified in most
jurisdictions as a processing aid and so does not need to be listed
on ingredient lists.
Citric acid is an alpha hydroxy acid and used as an active
ingredient in chemical peels.
Citric acid is commonly used as a buffer to increase the solubility
of brown heroin. Single-use citric acid sachets have been used as
an inducement to get heroin users to exchange their dirty needles
for clean needles in an attempt to decrease the spread of HIV and
hepatitis. Other acidifiers used for brown heroin are ascorbic
acid, acetic acid, and lactic acid; in their absence, a drug user
will often substitute lemon juice or vinegar.
Citric acid is used as one of the active ingredients in the
production of antiviral tissues.
