Aqua- EAU ●
TL;DR. This ingredient is the primary solvent and carrier in many beauty and personal care formulas. It dissolves compatible actives, sets product texture, and forms the continuous phase in gels, lotions, creams, cleansers, and sprays.
What does Aqua- EAU do in a cosmetic formula?
This ingredient is the primary solvent and carrier in many beauty and personal care formulas. It dissolves compatible actives, sets product texture, and forms the continuous phase in gels, lotions, creams, cleansers, and sprays.
Is Aqua- EAU clean?
This ingredient is broadly accepted in clean-beauty frameworks and is generally well-tolerated. Clean-standard attention is usually about purity, microbial quality, and preservation of the finished formula rather than concern about the material itself.
Is Aqua- EAU sustainable?
This material is commonly sourced from purified municipal, spring, or well supplies, so its footprint depends on local scarcity, purification, heating, cooling, and transport. It is non-persistent and part of natural environmental cycles, but responsible use matters in high-volume manufacturing.
Is Aqua- EAU COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards, although it does not count toward organic content and must meet quality specifications. From a Green Chemistry view, it is a preferred benign solvent, with the main tradeoffs tied to energy use and resource management.
How does Aqua- EAU work chemically?
This compound is a small polar molecule with strong hydrogen bonding and a high dielectric constant, which makes it effective for dissolving salts, humectants, acids, bases, and many botanical extracts. It commonly makes up 50 to 90 percent of emulsions and cleansers, supports microbial growth in finished products, and influences pH, viscosity, hydrolysis rate, and preservative demand.
