TUBITAK Project, 2209-A - Üniversite Öğrencileri Araştırma Projeleri Destekleme Programı, 2021 - 2022
Aim: The aim of this project was to develop an anti-aging and moisturizing
product formulation that protects the skin against blue light, UVA and UVB rays.
Another important goal was to design an environmentally friendly formulation, in
order to significantly reduce water and CO2 footprints and overall environmental
impact. Different brochures have also been planned to deliver valuable information to
consumers and to selling point personnel who help the consumer to make product
selection.
Materials and methods: As a result of literature search and pre-formulation
studies a preliminary formulation was designed, appropriate type and amount of
sunscreen materials were selected and tested with the tool of provided by BASF. As
a result of these formulation studies a final oily product formulation was selected for
further stability and efficacy testing. Stability tests were conducted 4 different
conditions and samples were tested at predetermined time points. Efficacy testing was
monitored by measuring moisturization potential and protection against blue light.
Result: According to BASF Sunscreen Simulator, SPF was 38, in-vitro UVA
protection factor (ISO 24443) 18.3 and critical wavelength was 373 nm . Skin
moisture level increased by 73.2 % according to the corneometric measurement made
by Courage & Khazaka MPA 580 device while placebo caused only a 23.8% increase.
The occlusive characteristic of the product led to a reduction of TEWL measurement
by %7.14.
Conclusion: Due to the broad spectrum filters use in the formulation, the product
protects from UVB,UVA and blue light.This formulation was designed with oils and
oil-soluble active ingredients to comply with waterless beauty concept. Water is added
before use to turn it into a lotion. Corneometric measurement proved that product has
a very good moisturizing effect. Patent eligibility search was done and the formulation
was found to be eligible, further action will be taken for registration.
