Triisopropanolamine ●
TL;DR. This ingredient is primarily used as a pH adjuster and neutralizing agent, especially to help thicken carbomer and acrylate-based gels. It can also support emulsion stability by bringing a formula into its target pH range.
What does Triisopropanolamine do in a cosmetic formula?
This ingredient is primarily used as a pH adjuster and neutralizing agent, especially to help thicken carbomer and acrylate-based gels. It can also support emulsion stability by bringing a formula into its target pH range.
Is Triisopropanolamine clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic alkanolamine and can raise nitrosamine-related scrutiny when paired with nitrosating systems. It is generally a formula-support material rather than a skin-benefit ingredient, and tolerance depends strongly on final product pH and concentration.
Is Triisopropanolamine sustainable?
This material is typically petroleum-derived, with feedstocks linked to propylene chemistry and ammonia chemistry. It is water-soluble and has low expected bioaccumulation, but its renewable sourcing profile is weak and biodegradability data are less favorable than many plant-derived pH adjusters.
Is Triisopropanolamine COSMOS-approved?
This ingredient is not aligned with COSMOS-natural or COSMOS-organic formulation expectations and is not a typical permitted pH adjuster in those standards. From a Green Chemistry lens, it is compromised by synthetic petrochemical sourcing and less preferred end-of-life characteristics, despite being effective at low use levels.
How does Triisopropanolamine work chemically?
The molecule is a tertiary alkanolamine with multiple hydroxyl groups, which lets it neutralize acidic polymers and form salts that increase gel viscosity. It is typically used in small amounts to reach the target pH, often around skin-compatible ranges near pH 5 to 7, and it should be formulated with attention to nitrosating impurities and final alkalinity.
