9))tridecane ●
TL;DR. This ingredient is primarily a lightweight volatile emollient and solvent. It helps spread oils, pigments, and UV filters, then leaves a dry, non-greasy skin feel.
What does 9))tridecane do in a cosmetic formula?
This ingredient is primarily a lightweight volatile emollient and solvent. It helps spread oils, pigments, and UV filters, then leaves a dry, non-greasy skin feel.
Is 9))tridecane clean?
It is generally well tolerated, with low sensitization potential and little clean-standard controversy. The main clean-beauty caveat is source transparency, since the same label name can refer to plant-derived or petroleum-derived material.
Is 9))tridecane sustainable?
This material can be made from plant fatty acids or petroleum fractions, so its sustainability profile depends heavily on supplier sourcing. Linear hydrocarbon chemistry is generally more biodegradable than silicone fluids, but fossil-derived grades carry a weaker renewable-sourcing profile.
Is 9))tridecane COSMOS-approved?
It may be accepted in COSMOS-natural formulations, and in COSMOS-organic products as a non-organic natural-origin ingredient, when derived from approved renewable feedstocks and made through allowed processes. Petroleum-derived grades do not align as well with COSMOS or Green Chemistry principles.
How does 9))tridecane work chemically?
The molecule is a straight-chain, saturated 13-carbon hydrocarbon, nonpolar and water-insoluble, which makes it useful for dissolving and dispersing lipophilic ingredients. It is typically used in anhydrous systems, emulsions, makeup, and sunscreens, and it is broadly pH-insensitive because it has no ionizable functional group.
