What does this ingredient do in an antiperspirant?
CosIng lists Butylene Glycol with the functions humectant, skin conditioning, solvent, viscosity controlling and fragrance.
Part of a system, not a label in isolation
In roll-ons and gels it helps dissolve extracts and skin care ingredients and affects how the base feels. It does not reduce sweating.
Butylene Glycol is not listed in the restrictive annexes of EU Regulation 1223/2009; the safety assessment applies to the finished formula.
It is generally well tolerated; on irritated or freshly shaved skin, a reaction to the finished formula is possible.
Butylene Glycol is not the same as Propylene Glycol or Pentylene Glycol: they are related glycols with different carbon chain lengths.
