Polyglyceryl-2 ●
TL;DR. This ingredient primarily functions as a humectant and solvent, helping bind water in the formula and improve the feel of water-based products. It can also support mildness and ingredient dispersion in cleansers, creams, and serums.
What does Polyglyceryl-2 do in a cosmetic formula?
This ingredient primarily functions as a humectant and solvent, helping bind water in the formula and improve the feel of water-based products. It can also support mildness and ingredient dispersion in cleansers, creams, and serums.
Is Polyglyceryl-2 clean?
From a clean-beauty perspective, this ingredient is generally well tolerated, low in sensitization concern, and not a common restricted-list trigger. Quality depends on controlled processing and low residual catalyst or byproduct levels.
Is Polyglyceryl-2 sustainable?
This material is commonly made from glycerin feedstocks, which may be plant-derived or synthetic depending on the supplier. It is expected to be readily biodegradable and has low persistence concern in rinse-off and leave-on use.
Is Polyglyceryl-2 COSMOS-approved?
It is generally compatible with COSMOS natural and organic formulations when derived from permitted feedstocks and manufactured under compliant processing rules. Its Green Chemistry fit is favorable when renewable glycerin is used, with good biodegradability and a relatively simple production pathway.
How does Polyglyceryl-2 work chemically?
The molecule is a low-molecular-weight polyol with multiple hydroxyl groups, which explains its water binding, solvent behavior, and compatibility with aqueous systems. It is typically stable across normal cosmetic pH ranges and pairs well with other humectants, surfactants, and emulsifier systems.
