Water for Cosmetic Formulations

Yes, sterile water for irrigation is generally suitable for use in cosmetic formulations. This type of water is typically high-purity distilled, de-ionized, and sterilized, which meets the requirements for cosmetic manufacturing.

Using high-purity water is crucial in cosmetic formulations to prevent impurities from interfering with the stability, efficacy, and safety of the product. Impurities like minerals, ions, and microorganisms found in tap water can cause issues such as:

• Instability of emulsions
• Reduced effectiveness of preservatives
• Discoloration or changes in odor
• Microbial contamination

If high-purity distilled water is not available, suitable alternatives include:

• Deionized (DI) Water: Water that has had most of its mineral ions removed.
• Reverse Osmosis (RO) Water: Water that has been filtered under pressure through a semipermeable membrane to remove ions, molecules, and larger particles.

Tap water is generally not recommended for cosmetic formulations due to varying levels of minerals, chlorine, and potential microbial contamination.

To check the suitability of water for cosmetic use, you can measure its purity. A common and useful piece of equipment for this is a TDS meter (Total Dissolved Solids meter). This device measures the concentration of dissolved solid substances in water, giving an indication of its purity. For cosmetic use, water with a very low TDS reading (ideally close to 0 ppm) is preferred.

High-purity water like Purified Water, TDS Limit 1PPM) is ideal for cosmetic applications.
