New multifunctional surfactants from natural phenolic acids

Area of Science:

• Cosmetic Science
• Organic Chemistry
• Materials Science

Background:

• Cosmetic ingredients require multifunctional properties like UV protection and antioxidant activity.
• Natural sources like amino acids and hydroxycinnamic acids are increasingly explored for novel cosmetic applications.

Purpose of the Study:

• To synthesize novel multifunctional molecules for cosmetic applications.
• To evaluate the emulsifying, UV-protecting, and radical scavenging activities of these new compounds.

Main Methods:

• Synthesis involved coupling protected amino acids with ferulic or caffeic acid.
• Lipophilicity was modulated via reaction with dodecyl bromide, creating water/oil (W/O) emulsifiers.
• Hydrophilicity and oil/water (O/W) emulsifying properties were enhanced through deprotonation and salification.

Main Results:

• Successfully synthesized multifunctional molecules with tunable lipophilic and hydrophilic properties.
• Compounds demonstrated significant emulsifying capabilities for both W/O and O/W formulations.
• The molecules exhibited UV-protecting and radical scavenging activities.

Conclusions:

• The novel multifunctional surfactants derived from natural sources meet modern cosmetic ingredient requirements.
• These compounds show potential for treating various skin conditions related to oxidative stress and UV damage.
• The synthetic strategy allows for tailored properties, offering versatile applications in skincare formulations.
