What does this ingredient do in an antiperspirant?

As an antioxidant, it slows reactions with oxygen that make oils and fragrance ingredients go rancid or change their smell or color.

Part of a system, not a label in isolation

In antiperspirants it usually sits near the end of the list: oil-based sticks and fragranced aerosols need only a little of it. Its job is to keep the product stable, not to care for the skin.

Regulatory and scientific context

Since 2023, BHT has been restricted in the EU under Annex III of Regulation 1223/2009: up to 0.8% in leave-on and rinse-off products (lower limits apply to mouthwash and toothpaste). The CIR found BHT safe at the low concentrations used in cosmetics.

What sensitive skin should consider

According to the CIR, limited skin studies and clinical reports showed no significant irritation, sensitization or photosensitization.

Do not confuse with

It is not the same as BHA (butylated hydroxyanisole), a different antioxidant with its own assessment. Nor is it a preservative: other ingredients protect against microbes.
