Inactive: Water ●
TL;DR. This ingredient is the primary solvent and diluent in many formulas, dissolving salts, humectants, acids, preservatives, and botanical extracts. It also helps set product texture, spread, and the final concentration of active ingredients.
What does Inactive: Water do in a cosmetic formula?
This ingredient is the primary solvent and diluent in many formulas, dissolving salts, humectants, acids, preservatives, and botanical extracts. It also helps set product texture, spread, and the final concentration of active ingredients.
Is Inactive: Water clean?
From a clean-beauty perspective, this ingredient is well-tolerated, non-sensitizing, and not a restricted-list concern. Quality depends on purification and microbial control, so cosmetic-grade use relies on purified inputs and properly protected formulas.
Is Inactive: Water sustainable?
This material is widely available and typically sourced locally before purification, so transport footprint is usually low. It is readily returned to natural cycles, but responsible manufacturing still considers consumption, effluent quality, and regional scarcity.
Is Inactive: Water COSMOS-approved?
It is permitted under COSMOS organic and natural standards. It aligns well with Green Chemistry as a benign solvent, though purification energy and resource use still matter at manufacturing scale.
How does Inactive: Water work chemically?
The molecule is small, highly polar, and strongly hydrogen-bonding, which explains its ability to dissolve electrolytes and many polar cosmetic ingredients. It is commonly the largest phase in emulsions, gels, and cleansers, and its level affects viscosity, preservative demand, freezing point, and pH measurement.
