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.

Food and Beverage Industry

Preservative: Inhibits bacteria and fungi growth, extending shelf life of products (e.g., jams, jellies, canned goods, beverages).

Flavour Enhancer: Adds tangy, refreshing taste to soft drinks, candies, and other foods.

Emulsifier: Stabilises mixtures in products like salad dressings and ice creams.

Household Cleaning

Descaling Agent: Cleans kettles, coffee makers, and dishwashers by breaking down mineral deposits.

Metal Chelator: Removes soap scum, hard water stains, and rust effectively.

Eco-Friendly Cleaner: Biodegradable and naturally derived, suitable for kitchens and bathrooms.

Personal Care Products

pH Adjuster: Ensures stability and effectiveness in shampoos, conditioners, and skincare products.

When working with citric acid in cosmetic formulations, it's essential to use precise measurements to achieve the desired pH balance and product effectiveness. Proper dissolution is crucial; citric acid should be dissolved in water or another suitable solvent to ensure it fully integrates into the formulation. Monitoring and adjusting pH levels is necessary, as citric acid can significantly impact the acidity of the final product. Safety is also important; wearing gloves and safety goggles can prevent skin and eye irritation during handling. Start with small quantities of citric acid and gradually increase to reach the desired effect, avoiding over-acidification.

Compatibility with other ingredients must be checked to prevent adverse reactions. Store citric acid in a cool, dry place to maintain its efficacy and avoid clumping or degradation. Clearly labeling products that contain citric acid, including concentration levels and any pH adjustments, is important for transparency and safety. Conduct patch tests to ensure formulations are safe and non-irritating for skin application. Additionally, keeping detailed records of formulations and pH adjustments helps maintain consistency and quality control in future batches.
