Isopentyliol ●
TL;DR. This ingredient is primarily used as a humectant and solvent, helping formulas hold water while improving the dissolution of fragrance, preservatives, and other small actives. It can also support preservative systems by lowering water activity.
What does Isopentyliol do in a cosmetic formula?
This ingredient is primarily used as a humectant and solvent, helping formulas hold water while improving the dissolution of fragrance, preservatives, and other small actives. It can also support preservative systems by lowering water activity.
Is Isopentyliol clean?
From a clean-beauty perspective, it is generally considered low-irritation and not a common allergen, with fewer concerns than many traditional solvent systems. Its main friction point is that it is usually a synthetic glycol-type material, so some standards treat it less favorably than clearly renewable alternatives.
Is Isopentyliol sustainable?
This material is commonly made from petrochemical feedstocks, although lower-impact routes may exist depending on supplier. It is expected to be readily biodegradable and is not known for long-term environmental persistence.
Is Isopentyliol COSMOS-approved?
It is not typically aligned with COSMOS-organic as a natural-origin ingredient, and acceptance under COSMOS-natural depends on the exact manufacturing route and certification documentation. From a Green Chemistry lens, its biodegradability and multifunctionality are positives, while nonrenewable sourcing is the main compromise.
How does Isopentyliol work chemically?
The molecule is a small branched diol, which explains its water compatibility, humectancy, and ability to help solubilize moderately polar materials. It is generally stable across normal cosmetic pH ranges and is often used in leave-on formulas at low single-digit percentages, with higher levels possible when it is serving as a primary solvent or hydration aid.
