3-Aminopropan-1-Ol

TL;DR. This ingredient is an alkaline pH adjuster and neutralizing agent, used to raise formula pH and neutralize acidic gelling polymers such as carbomers.

What does 3-Aminopropan-1-Ol do in a cosmetic formula?

This ingredient is an alkaline pH adjuster and neutralizing agent, used to raise formula pH and neutralize acidic gelling polymers such as carbomers.

Is 3-Aminopropan-1-Ol clean?

Clean frameworks tend to view it as a synthetic alkalizer with irritation potential in concentrated or high-pH systems, rather than a skin-benefit active. It also carries amine-related nitrosation considerations, so formulators typically control pH, impurities, and contact with nitrosating agents.

Is 3-Aminopropan-1-Ol sustainable?

This material is usually made through petrochemical routes from small C3 intermediates. It is water-soluble, has low bioaccumulation potential, and is expected to biodegrade more readily than persistent silicone or fluorinated materials.

Is 3-Aminopropan-1-Ol COSMOS-approved?

This ingredient is not generally permitted as a standalone input in COSMOS natural or organic formulas, which gives it weak COSMOS alignment. Its Green Chemistry profile is mixed: it is efficient at low use levels and likely biodegradable, but it relies on nonrenewable feedstocks and requires amine-management controls.

How does 3-Aminopropan-1-Ol work chemically?

The molecule is a small bifunctional C3 compound with one primary amine and one primary alcohol; the amine has a pKa around 9.7, so it is strongly alkaline in water and mostly protonated near skin pH. Use is typically as needed for neutralization, often below 1%, and formulation should account for final pH, nitrosating systems, and strong oxidizers.
