Pentyelene Glycol ●
TL;DR. This ingredient is a multifunctional humectant and solvent that helps draw water into the skin, improve slip, and dissolve or distribute actives. It also supports preservation by lowering water activity and making formulas less hospitable to microbes.
What does Pentyelene Glycol do in a cosmetic formula?
This ingredient is a multifunctional humectant and solvent that helps draw water into the skin, improve slip, and dissolve or distribute actives. It also supports preservation by lowering water activity and making formulas less hospitable to microbes.
Is Pentyelene Glycol clean?
It is generally accepted in clean-beauty frameworks, with low sensitization rates and no broad restricted-list concerns. At higher levels or on compromised skin, it can cause temporary stinging or irritation for some users.
Is Pentyelene Glycol sustainable?
This material can be made from petroleum feedstocks or from plant-derived sugars, so its sustainability profile depends on sourcing. It is generally considered readily biodegradable and does not raise major persistence or bioaccumulation concerns.
Is Pentyelene Glycol COSMOS-approved?
It can be permitted under COSMOS-natural and COSMOS-organic when the grade is from approved natural-origin feedstocks and made through accepted processing. From a Green Chemistry view, the better fit is the bio-based route, paired with biodegradability and a relatively simple multifunctional role in formula design.
How does Pentyelene Glycol work chemically?
The molecule is a small five-carbon diol, which explains its water miscibility, humectancy, solvent behavior, and preservation-boosting effect. It is commonly used around 1 to 5% in leave-on products, is stable across typical cosmetic pH ranges, and pairs well with organic acids, glycols, and conventional preservative systems.
