Glycerin1 ●
TL;DR. This ingredient is primarily a humectant, helping formulas bind water and reduce moisture loss from skin and hair. It also improves glide, supports preservation systems by lowering water activity, and can reduce the drying feel of surfactant formulas.
What does Glycerin1 do in a cosmetic formula?
This ingredient is primarily a humectant, helping formulas bind water and reduce moisture loss from skin and hair. It also improves glide, supports preservation systems by lowering water activity, and can reduce the drying feel of surfactant formulas.
Is Glycerin1 clean?
Clean-beauty frameworks generally view this ingredient as well tolerated and low concern, with no common restricted-list friction. At very high levels it can feel tacky or sting on already sensitized skin, but it is broadly compatible with sensitive-skin positioning.
Is Glycerin1 sustainable?
This material is commonly sourced from plant oils as a byproduct of soap or fatty-acid production, though it can also be made synthetically. It is readily biodegradable, water soluble, and not known for environmental persistence.
Is Glycerin1 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when sourced and processed according to the standard. Its renewable sourcing options, biodegradability, and simple processing profile fit Green Chemistry principles well.
How does Glycerin1 work chemically?
This molecule is a small three-carbon triol with three hydroxyl groups, which explains its strong water-binding behavior and full water miscibility. Typical use levels are about 1 to 10 percent in leave-on skin care, higher in some rinse-off or treatment formats, and high levels can create tackiness unless balanced with emollients or film formers.
