Polytechnic student encapsulates memories in nano-emulsion perfume

Pham Kim Quoc Cuong, a 2019 cohort student of the Chemical Engineering English Program at Ho Chi Minh City University of Technology, together with his team, has developed a “Made in Vietnam” perfume oil that offers exceptional longevity and a wide spectrum of scents.

Using the Phase Inversion Temperature (PIT) method, they add a measured amount of water into a mixture of surfactants and natural essential oils, then continuously stir at room temperature to form a nanoemulsion. Under intense dispersion, water and essential oil molecules are broken down into ultra-fine particles. Once reduced to the nano scale, the formula stabilizes without the need for alcohol.

When sprayed on skin, the water and essential oils are absorbed, creating a moisturizing effect. Because the perfume is alcohol-free, it does not follow the traditional top–heart–base note structure; instead, the fragrance accords radiate simultaneously. Another advantage of this system is that the nanoemulsion distributes evenly, eliminating the need to shake before use.

Cuong shared that his greatest dream is to apply the knowledge he has gained at the university to create high-quality perfumes for Vietnamese people, crafting bespoke scents for individual customers. His vision includes recreating “olfactory memories” such as the aroma of wooden altars, old cabinets, or vintage paper, allowing people to relive their personal stories through scent.
