Uses of Citric Acid in Cosmetics

Citric acid is one of the many organic acids you can use in numerous fields such as the food industry, the pharmaceutical industry, and the cosmetic industry. Being a normal acid, citric acid can change the pH of food making it famous in most households for its sour nature. A seasoning, a component to control mold growth, and so much more; the use of citric acid in food is an aspect not worth discussing. It has the same function in cosmetics, which is why it should also be discussed here. This article focuses on citric acid in cosmetics concerned with its medical citric acid uses for the skin, food that has citric acid, cleaning with citric acid, hair, and cosmetics.

What is Citric Acid Raw Material?

Citric acid is an organic acid that is present in many fruits most of which are citrus fruits such as lemons and oranges. It is involved in metabolism and is best recognized for being a pH controller, a compound that binds to metal ions, and an antioxidant. Regarding cosmetics, these characteristics of citric acid in cosmetics make citric acid indispensable.

Natural Sources of Citric Acid

Marmalade, pineapples, grapes, and raspberrys are some of the fruits which contain a lot of citric acid. Among these, lemon juice is the most important, which consists of 6-10% citric acid. Thus, citric acid containing food products are not only plants but are also products of the carbohydrate, protein and lipid metabolism in animal tissues.

Physical Properties of Citric Acid

Citric acid powder is exhibited in two forms which are anhydrous citric acid or citric acid monohydrate and this powder is soluble easily in water and ethanol. The chemical compound is soluble in water and has a very sharp acidic flavor which makes it suitable for most applications. Perhaps more importantly, citric acid can be easily dissolved in water but it cannot be dissolved in most other materials like ether and benzene so its uses are relatively few.

Citric acid is a very important ingredient in skincare where it plays the role of exfoliating the skin, lightening the skin, and offering protection against harm caused by free radicals. These properties are ascribed to its ability to alter cells’ pH and gain an ability to enhance certain turnover rates of cells, and for this very reason, it is used actively in cosmetics production.

What are Some Positives of Citric Acid in Cosmetics?

The use of citric acid in cosmetic products benefits from the chemical formulas of this acid. Here are the key advantages of citric acid:

Citric Acid Helps with pH Adjustment

It is therefore evident that adherence to the appropriate pH level in cosmetics cannot be over-emphasized. The citric acid in skin care is used to maintain the state of our pH which is a basic formula for skin and hair. Many skincare, actives, thickeners, and colorants may function optimally depending on the pH levels. Many formulations, if not balanced for pH, can become either too irritating or simply not effective at all. Citric acid is also recommendable and is a natural solution that can help in realizing the needed pH level.

Citric Acid Contributes to Product Stability and Longevity

Citric acid has good effects on the stability and the length of the shelf life of cosmetic products. It achieves stabilization of the pH to enhance the effectiveness of citric acid as a preservative in cosmetics and antioxidants; thus, eliminating spoilt foods. Citric acid used in cosmetics can chelate with metal ions and hence it hinders the action of the ions in ruining formulations. There are also uses of citric acid in soap. In soap products, it aids in reducing the formation of soap scum and enriched the soap products’ usability and appearance.

Citric Acid Delivers Skin Cleansing and Anti-Aging Benefits

Citric acid for skin is another type of Alpha Hydroxy Acid (AHA) most famous for its skin exfoliating abilities. It deep cleanses the skin to clear away dull surface cells, excess dirt, and everyday pollutants, ultimately leaving your skin looking smoother and more vibrant. AHAs such as citric acid are employed in chemical peels and acne treatments because they help enhance skin tone and correct cases of hyperpigmentation. Citric acid also reduces free radical formation aids in making the skin firmer and gives an appearance of the skin that is much younger.

In hair care, citric acid is added to shampoos to decrease pH and hopefully solve hair problems such as frizzy hair and unruly hair. It is also added to hair rinses that color or tone hair.

Citric Acid Creates Effervescence in Bath Bombs

Powdered citric acid for cosmetics is widely used in bath bombs which have already been discussed in the article. In contact with water, citric acid mixed with baking soda releases a carbon dioxide bubble due to the reaction in water. This fizzy reaction intensifies the feeling and the overall experience turning the basic bath into a relaxing bath in a spa.
