citric acid
It is a common cosmetic ingredient widely used in personal care products as a pH adjuster and formulation stabilizer. It is a weak organic acid that occurs naturally in citrus fruits and is produced synthetically to high purity levels suitable for cosmetic use.
In cosmetics, citric acid helps balance the pH of the final product, improving skin compatibility and supporting the stability of active ingredients and preservation systems. It is also used in carefully measured concentrations to enhance the overall feel of the product without causing irritation when the recommended proportions are followed.
Benefits
- It helps to regulate and adjust the pH level.
- It contributes to improving the stability of cosmetic formulations.
- Enhances product compatibility with the skin
- It supports the effectiveness of preservation systems.
- Effective at low concentrations
- Compatible with most cosmetic ingredients

- Manufacturing stage: Aqueous phase or final modification stage
- Preparation method: Dissolve in water before adding to the formula or use as a diluted solution to adjust pH.
- Temperature: Stable within normal cosmetic manufacturing temperatures
- Recommended pH range for the final product: depending on the product type (usually between 4.0 – 6.5 for skincare products)
- Important structural notes:
- Add gradually while continuously measuring the pH level.
- Do not use directly in high concentration without dilution.
- Excessive use may cause an imbalance in the formula.
Recommended ratios
- As a pH regulator: 0.05% – 0.5% (as needed)
