PROPANOL ●
TL;DR. This ingredient is a volatile solvent and denaturant that helps dissolve fragrance, resins, and other hard-to-solubilize materials while speeding dry-down. It can also support preservation systems through its alcohol activity.
What does PROPANOL do in a cosmetic formula?
This ingredient is a volatile solvent and denaturant that helps dissolve fragrance, resins, and other hard-to-solubilize materials while speeding dry-down. It can also support preservation systems through its alcohol activity.
Is PROPANOL clean?
From a clean-beauty perspective, it is generally acceptable but not especially gentle at higher levels because volatile alcohols can increase dryness, stinging, or barrier disruption in leave-on formulas. It is not a major allergen-list ingredient, but its use level and product format matter.
Is PROPANOL sustainable?
This material is most often made from fossil-derived feedstocks, although renewable routes are technically possible. It is readily biodegradable, but its volatility makes it a VOC consideration in high-use or aerosol-type products.
Is PROPANOL COSMOS-approved?
It has limited alignment with COSMOS-organic unless sourced and processed from approved natural feedstocks, while conventional fossil-derived grades are a poor fit for natural-formula standards. From a Green Chemistry lens, it is a simple and biodegradable solvent, but fossil sourcing and VOC emissions keep the profile mixed.
How does PROPANOL work chemically?
The molecule is a small three-carbon primary alcohol, fully miscible with water and many organic solvents, with a boiling point around 97 °C. Use levels range from low single digits as a solvent to much higher in fast-drying or antiseptic formats, and it is broadly stable across normal cosmetic pH ranges.
