Why is water essential for cosmetics?
• The vast majority of cosmetic products contain water.
• Certain machines require water to operate.
• Production and packaging tools and work areas are also cleaned with water.
How can its use be optimized? What water quality is required for which use(s)?

Water as a cosmetic ingredient in a formula

Considered a cosmetic raw material in its own right, water must meet perfectly mapped and controlled quality standards:
• Ion content (calcium, magnesium, etc.)
• Impurity content (sulfates, phthalates, PFAS)
• Heavy metal content
• Microbiological quality

The quality of the water used in the manufacture of cosmetic products must be reproducible and regularly monitored, as it can have a direct impact on the quality of the products manufactured:
• Physicochemical impact
• Impact on stability over time
• Microbiological impact

If water is to be considered a “real” raw material in the formula, the control methods must be relevant!

Water is very often considered to be the main solvent in the formula (see: making the QSP in water). But it is not insignificant, and its composition can vary greatly depending on its origin. What we see in …
