What Is Uses Of Citric Acid In Cosmetics

The uses of citric acid in cosmetics cover a wide range of applications, but it would be ideal to have knowledge about citric acid, what peculiarities it possesses, how it is obtained, as well as the main physical features, and the chemical characteristics that allow it to bring special functions to the cosmetics area.

Citric acid

When speaking of acids with characteristics like this, is to speak of carbon compounds, or organic, found naturally in many fruits, for example oranges, over time has been associated with this fruit citrus, also with lemon, but there are others such as tangerines, Grapefruit, grapefruit, lime, guavas, strawberries, pineapples, passion fruit, various types of berries, but in other vegetables among which are broccoli, tomatoes, carrots, is also found, although in smaller proportions.

Among the plants most coveted for extracting citric acid is a species of fungus, Aspergillus Niger, which provides very high volumes of the compound.

Citric acid is present as a product resulting from metabolisms carried out by each of the living organisms that inhabit the planet.

Citric acid, main qualities

This acid is one of those that do not have the characteristic of dissociating completely in solutions, and because of its lower concentration of ions, is classified among the weak acids, to which a large number of organic acids belong.

Due to the set of peculiarities it possesses, the uses of citric acid in cosmetics cover many products, but not only in this branch, the applications in different areas of economy and production are extensive.

The molar mass of citric acid is 192.124 g/mol, with a density that reaches 1.66 g/cm3, and has a melting point of 175 degrees Celsius, with a boiling point of 310 degrees Celsius. It has an acidity of 3.15 for 1, 4.77 for 2 and 6.40 pKa for 3.

Citric acid has high solubility in liquids with water-like characteristics, reaching values of 3. 83 × 105 mg/L if the temperature is around 25 degrees Celsius, the solubility of this acid is also very good in compounds of the type of acetone, alcohol, and ethyl ethanoate, being also soluble in polar solvents, these include ethanol, and ethyl acetate, on the contrary the solubility of this acid in aromatic substances is null, especially in specific compounds, of the type of benzene, toluene, chloroform, and xylene.

The formula of the molecular type of citric acid is C6H8O7, with which the constitution of the molecules of this compound can be deciphered, the symbol C6 representing the 6 carbon atoms it contains, the H8 the 8 hydrogen atoms, and the O7 the 7 oxygen atoms.

With respect to the formula of the structural type is represented C3H5O(COOH)3, where the three carboxyl groups (COOH)3 are appreciated, and the formula of the semi-developed type has this form HOOC - CH2 -HOC (COOH) -CH2 -COOH.

The presence of the three carboxyl groups in the acid molecules can also be seen at a glance.

This acid has the ability to release hydrogen ions, and thanks to this peculiarity of the substance, it is considered a polyprotic acid, which means that it belongs to the acids that can donate and accept hydrogen bonds with extreme ease, this quality is also what allows the great affinity of the acid with liquids such as water.

The wide variety of uses of citric acid in cosmetics, are propitiated by this accumulation of properties that this acid possesses.
