Abstract: The functional limitations of surfactant emulsions led one Shiseido team to develop a "novel, ultimate emulsification system" to overcome those limitations. Read on to learn more about this system, which was presented at the IFSCC Congress in Orlando.

During the IFSCC Congress, Yuki Sugiyama of Shiseido spoke at the Emerging Market Trends and Insights session on core-corona particles and their emulsifying capabilities.

She began by discussing the functional limitations of surfactant emulsions, including their vulnerability to coalescence, sticky texture during application and deterioration through re-emulsification.

According to Sugiyama, this led her team's efforts to “develop a novel, ultimate emulsification system that overcomes the limitations of conventional technologies and improves the flow of cosmetic application to the skin.”

During the IFSCC Congress, Yuki Sugiyama of Shiseido spoke at the Emerging Market Trends and Insights session on core-corona particles and their emulsifying capabilities.

She began by discussing the functional limitations of surfactant emulsions, including their vulnerability to coalescence, sticky texture during application and deterioration through re-emulsification.

According to Sugiyama, this led her team's efforts to “develop a novel, ultimate emulsification system that overcomes the limitations of conventional technologies and improves the flow of cosmetic application to the skin.”

Ideally, they were looking for a system with effective preparation and high stability, pleasant texture and long-lasting functionality. What they found was the core-corona particle.

Applications were described as follows.

  • In sun care and makeup, they impart high water-resistance and give dewy, refreshing textures;
  • in skin care, they provide high barrier function with smooth textures;
  • for hair care, they can create non-dripping, milky reparative hair oils; and
  • in fragrance, they enable long-lasting, milky, alcohol-free fragrances.

Sugiyama noted core-corona particles are highly resistant to coalescence, which leads to unprecedented emulsification. Finally, a small amount of these “soft” polymer particles leads to favorable textures and requires less re-emulsification, which results in long-lasting functionality.
