Long Lasting Fragrance Discovered
The worry that the smell of a scent does not last long on hair is common. A team of researchers reports discovery of certain cyclic peptides which could bind to hair under shampooing conditions in the presence of certain surfactants. Their discovery of fragrance that “stick” to hair is reported in ACS Applied Materials & Interfaces.
Fragrances are one of the most expensive shampoo ingredients. These floral- or fruity-smelling compounds evaporate rapidly or are easily washed away when surfactants, such as shampoos, are used.
The researchers say that the newly designed peptide were about 20 times more efficient to stick onto hair than those that lacked a peptide. This could effectively keep fragrance smell on hair for up to 24 hours after shampooing.
