Distilled water ●
TL;DR. This ingredient is the primary solvent and diluent in many formulas, dissolving or dispersing humectants, salts, polymers, surfactants, and preservatives. It also helps set texture, spread, and finished concentration.
What does Distilled water do in a cosmetic formula?
This ingredient is the primary solvent and diluent in many formulas, dissolving or dispersing humectants, salts, polymers, surfactants, and preservatives. It also helps set texture, spread, and finished concentration.
Is Distilled water clean?
It is broadly accepted across clean-beauty standards, with very low irritation potential and no restricted-list friction when properly purified. The main quality issue is microbial control after purification, so formulas still need suitable preservation or validated packaging.
Is Distilled water sustainable?
This material is a locally sourced commodity in most supply chains, with no persistence or bioaccumulation concern. Sustainability depends more on purification energy, regional scarcity, and manufacturing stewardship than on the molecule itself.
Is Distilled water COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic formulations, and it is not counted as organic content in organic-percentage calculations. Its Green Chemistry profile is strong because it is benign and non-persistent, though distillation adds energy demand.
How does Distilled water work chemically?
The molecule is small, highly polar, and hydrogen-bonding, which gives it strong ability to solvate ionic and polar materials. In emulsions, gels, and washes it is often the largest phase, commonly 50 to 95%+, and it is compatible across normal cosmetic pH ranges but requires microbial control because purity does not equal self-preservation.
