Product description


Demineralised water is highly purified water obtained by a reverse osmosis process from drinking water in which minerals, salts and impurities are removed. This process ensures extremely low conductivity and high purity of water, which is crucial for cosmetic and technical formulations. In cosmetics, it serves as an essential carrier ingredient that ensures the consistency, stability and safety of products. Its purity prevents unwanted reactions with active ingredients and makes it an ideal choice for natural and professional cosmetics.

Demineralised water is included in most of the products we have produced and we have published tutorials for their creation on our blog.


Key benefits:

  • High purity - free of minerals, salts and contaminants.

  • Improves formulation stability, does not affect pH or the effectiveness of the active ingredients.

  • Safe base for cosmetic products - minimizes the risk of microbiological contamination.

  • Universal use - suitable for all types of cosmetic formulations.

  • Made with sustainable reverse osmosis technology.


Suitable for products such as:

  • Skin and body creams, serums and emulsions.

  • Shampoos, conditioners and shower gels.

  • Micellar waters, toners and cleansing solutions.

  • Sunscreens and anti-age products.

  • Homemade DIY recipes and natural cosmetics.


Use in formulation:

  • Solubility: miscible with all common cosmetic ingredients.

  • Recommended dosage: used as the main ingredient in formulas (often 50-90% of the product content).

  • Incorporation: forms the basis of the aqueous phase in formulations.

  • Maximum processing temperature: stable under normal manufacturing conditions, resistant to high temperatures during processing.


Demineralised water obtained by reverse osmosis is an essential basic raw material that guarantees the purity, safety and stability of all cosmetic formulations.

Raw material safety grade according to EWG: 1 (low risk)


Frequently Asked Questions (FAQ)

What is the difference between distilled and demineralised water?
Distilled water is obtained by distillation, while demineralised water is purified using ion exchange or reverse osmosis. Both are low in minerals, but demineralised water has a more stable quality and is more environmentally friendly to produce.

Why is demineralised water needed in cosmetics?
Ordinary drinking water contains minerals and salts that can react with active ingredients and reduce the stability of products. Demineralised water ensures the purity and long shelf life of cosmetic products.

Can I use demineralised water at home for cosmetics?
Yes, it is ideal for DIY formulationsas it will ensure your products are more stable and resistant to spoilage.
