Citric Acid is a natural organic acid present abundantly in citrus fruits such as limes and lemons. It is also a raw material manufactured specifically for industrial purposes and used in a wide variety of products, including food and beverages, pharmaceutical preparations, detergents, bath products, skincare, haircare, and many other cosmetics.

Due to its diverse benefits, Citric Acid is popular in natural formulations: it can act as a pH adjuster and corrector, enhance the stability and shelf-life of products, contribute to the optimal performance of various actives, and also produce bubbles (fizzing) in desired bath or spa products.

Citric Acid also has known skincare benefits. It belongs to the AHA family of acids, which supports skin exfoliation to reveal a fresh and firmer complexion. It is also an antioxidant used in anti-aging applications.


Citric Acid Raw Material is a highly versatile product that can perform many functions within cosmetics. The fine, uniform consistency of this powder affords seamless dissolving in water and effortless mixing with other bath bomb ingredients for a high-quality product. Its multi-purpose nature is especially valuable in all-natural formulations as well.

Citric Acid helps with pH adjustment

The pH level of skincare formulations is an extremely vital factor deciding both quality and safety. An ideal pH enables products to become more safe, pleasant, and less irritating to use. In addition, the performance of some actives, colorants, thickeners, and other ingredients can also be dependent on the pH level; deviations can result in undesired outcomes such as discoloration, changes in viscosity, and poor product performance. If the formula ends up becoming too alkaline, Citric Acid can be added to lower the pH to a desired level.

Citric Acid contributes to product stability and life-span

By helping to stabilize the pH of formulations, Citric Acid can boost the longevity of cosmetic products. The pH can be a critical factor affecting how some preservatives work, and so its use ensures optimal stability for a safe-to-use product. Citric Acid is also known to have chelating properties; it binds (sequesters) to trace metal ions and thereby boosts the efficacy of added preservatives and antioxidants. This chelating action in useful in soap products as it binds to metal ions in water to help prevent rancidity and the creation of soap scum.

Citric Acid delivers skin cleansing and anti-aging benefits

In skincare, Citric Acid acts primarily as an exfoliant and an antioxidant. It is an AHA (Alpha Hydroxy Acid) and can be used in exfoliating formulations to help remove dead skin cells and dirt to reveal fresh, softer, smoother skin. AHAs are commonly used in cosmetic chemical peels and acne therapies for this reason. They can also reduce the appearance of scars, spots, and other pigmentation issues, thereby improving one’s complexion. As a protective antioxidant, Citric Acid protects the skin against the effects of free radical damage and also contributes to the toning and firming of the skin.

Citric Acid is often used in shampoo formulations to bring the pH levels down, which improves the hair’s appearance and manageability by reducing frizz. It can also be used in rinses to help lift or fade colors out of the hair.

Citric Acid helps produce effervescence (fizzing) in bath bombs

Fizzing reactions are used in cosmetics to create delightful, spa-like experiences with bath bombs and other bath fizzes. By far, the most popular acidic ingredient incorporated in bath bombs is Citric Acid. When such products are dropped into bathwater, the acid reacts with Baking Soda (Sodium Bicarbonate) to release bubbles of carbon dioxide, which is observable as effervescence (fizzing).


Citric Acid can be added to creams, lotions, serums, cleansers, shampoos, conditioners, bath products, and many other cosmetics.

To adjust pH:

A Citric Acid solution (50%) can be made by weighing an equal amount of Distilled Water and Citric Acid Raw Material. Gently add the Citric Acid into the water and stir well to mix. This solution can be stored in the desired container and used as needed; ensure the mixture is at room temperature before using. Add the solution drop by drop, mixing and closely monitoring the pH change until it reaches the desired level.

To make bath bombs:

Simply add the Citric Acid in its dry state along with the rest of your dry ingredients to create the bath bomb mixture and shape using the desired mold. The ratio of Citric Acid and Baking Soda used is typically 1:2. We have an in-depth guide on making your own DIY bath bombs here.


Citric Acid helps formulators elevate the performance, stability, and end experience of cosmetic products. It is soluble in water and therefore can be added to potentially any cosmetic that incorporates water; it cannot be used in anhydrous products such as body butters.
