What role does Aluminum Chlorohydrate play in this deodorant, and why is it effective?

Aluminum Chlorohydrate forms temporary plugs in sweat ducts, reducing the amount of sweat that reaches the skin surface, which provides a longer-lasting antiperspirant effect compared with deodorants that rely only on fragrance masking.

How often should the spray be applied and does it contain any controversial chemicals?

For optimal protection, apply the spray to clean, dry underarms once daily, reapplying after heavy exercise or excessive sweating; the formula includes flammable propellants (butane, isobutane, propane) and the preservative BHT, both of which are common in aerosol products but are sometimes debated for safety and environmental impact.

Q: Is Rexona 'Baron' deodorant spray safe for sensitive or acne-prone skin?

The spray contains aluminum chlorohydrate and silicone which are generally well tolerated, but the presence of fragrance allergens such as linalool, limonene and citronellol, as well as BHT, can trigger irritation in highly sensitive or acne-prone skin, so a patch test is recommended.

Product Insights

Rexona 'Baron' deodorant spray is an antiperspirant formulated for daily use, produced by Unilever in Brazil and sold in a pressurized pouch-flask. Its active ingredient, Aluminum Chlorohydrate (about 6 percent), provides strong sweat reduction, while cyclomethicone and caprylic/capric triglyceride give a lightweight, quickly drying feel. The formula relies on flammable hydrocarbon propellants (butane, isobutane, propane) and contains fragrance allergens such as linalool, limonene and citronellol, as well as the antioxidant BHT, which may irritate sensitive skin.

Comparative Analysis

Positioned as a high-efficiency antiperspirant spray, this Rexona variant targets consumers seeking strong sweat protection with a fast-dry, invisible finish, differentiating itself through a relatively high aluminum chlorohydrate concentration and a fragrance-rich profile in the Brazilian market.
