What does this ingredient do in an antiperspirant?
2-Octyldodecan-1-ol is a branched fatty alcohol. Its INCI functions are emollient, solvent and fragrance ingredient.
Part of a system, not a label in isolation
In sticks and roll-ons it improves glide and helps ingredients blend into an even base. It is not an antiperspirant active.
The CIR found Octyldodecanol safe in the present practices of use (1985 report, conclusion later reaffirmed).
As with other emollients, an individual reaction to the finished formula is possible.
Although it is classed as an alcohol, it is not ethanol: Octyldodecanol does not evaporate and does not make an alcohol-based formula.
