Main features and application of organogels in cosmetics
Cosmetic treatments aim at improving skin appearance through vehicles of good sensory properties. Those vehicles are mainly emulsions and gels designed to deliver safe and effective compounds to skin. Creams and serums are widely used to achieve these goals, but recently a new type of formulation known as organogels triggered scientific attention, particularly in the design of both topical and cosmetic formulations. It has been established that the lipophilic nature of organogels makes it an excellent candidate for the delivery of cosmetic molecules through skin. In a review, R.M. Martinez from the University of Sao Paulo and his co-authors discuss the properties and characteristics of organogels and present the advantages of the application of these systems in cosmetics.
Potential in complex systems like emulsions starts to emerge
The cosmetic applications of organogels are still not fully explored. Some of the advantages of using organogels are low‐cost composition, improvements in chemical stability of active molecules and physical stability of formulations, better rheological properties and enhanced delivery profiles. It is a versatile form to present hydrophilic and lipophilic molecules to skin and it can be modulated to achieve the expectations. Its simple and low‐cost preparation processes seem to be particularly beneficial to large‐scale uses, but their potential in complex systems like emulsions is also starting to emerge. There is still lack of information on safety and toxicological effects. However, a great amount of robust knowledge can be transferred from food and drug delivery applications, helping to turn organogels into a promising delivery system for cosmetics.
