AI Technical Summary

Technical Problem

Existing deodorant aerosol compositions fail to deliver a pleasant fragrance both on initial application and long after, often requiring the presence of silicone oil and lacking antiperspirant benefits.

Method used

A deodorant aerosol composition comprising activated aluminium sesquichlorohydrate (AI2OH4.4CI1.6 to AI2OH4.9CI1.1), a C16-C22 ester oil, and specific fragrance components like dihydromyrcenol, linalool, benzyl acetate, citronellol, linalyl acetate, alpha-methyl ionone, gamma undecalactone, and methyl dihydrojasmonate, without silicone oil, to provide a fresh, floral, and fruity odour perception and antiperspirant benefits.

Benefits of technology

The composition effectively maintains a pleasant fragrance and reduces malodour over time, providing both deodorant and antiperspirant benefits without silicone oil, ensuring a favorable consumer experience.
