Lipstick structure revealed by multimodal strain- and time-dependent rheology

Key Points

• The research aims to investigate the structural characteristics of lipsticks using advanced rheological methods.
• Utilized multimodal rheology to assess strain and time-dependent behaviors of lipsticks.
• Analyzed various formulations to understand the effects of different ingredients.
• Examined the interactions between waxes, oils, and pigments.
• Identified key structural properties influenced by the composition of waxes and oils.
• Revealed how time-dependent behaviors affect the stability and texture of lipsticks.
• Demonstrated that certain formulations enhance the cosmetic properties more effectively than others.
