Natural Plant Essential Oils to Replace Chemical Sunscreens, Achieving Both Environmental Friendliness and Skin Care!Jun 24, 2024

Professor Yi Guang-hui and his team at Hungkuang University have developed a "Natural Plant Compound Essential Oil." Using a UV-VIS spectrophotometer, the team measured the UV absorption spectra of 150 types of essential oils and selected the top five—birch, wintergreen, benzoin, sweet fennel, and cinnamon bark—for their high absorption values in the 200 nm to 400 nm range. These oils were then formulated into a compound essential oil with sunscreen effects. 

Natural Plant Compound Essential Oil: Dual Benefits of Sun Protection and Skin Care 

With global warming intensifying and the thinning of the ozone layer, increased ultraviolet (UV) radiation is causing more severe skin damage. Consequently, the use of commercial sunscreens has surged. However, most commercial sunscreens contain chemical filters that not only pose potential health risks through skin absorption but also contribute to environmental pollution and harm ecosystems. 

Experimental results show that the natural plant compound essential oil developed by the team offers sun protection comparable to 31% of the effectiveness of the commercial chemical sunscreen Octyl Methoxycinnamate (OMC), and provides 78% of OMC’s effectiveness in preventing hair color fading. Additionally, the compound essential oil, rich in natural plant ingredients, is gentle and non-irritating, offering moisturizing and soothing benefits for the skin. 

Advantages of Natural Plant Compound Essential Oil 

Environmentally Friendly: Replacing chemical sunscreens with natural plant extracts reduces environmental pollution. 

Skin-Friendly: Gentle and non-irritating, suitable for all skin types. 

Effective Sun Protection: Effectively blocks UVA and UVB rays, preventing sunburn, tanning, and skin aging. 

Hair Care Benefits: Helps prevent post-dye hair color fading, maintaining vibrant hair. 

Versatile Applications: Can be used in sunscreen lotions, creams, gels, facial serums, and hair care oils. 

Recognized with Multiple International Invention Awards 

Professor Yi noted that the team's natural plant compound essential oil has won numerous accolades, including the gold medal at the 21st Malaysia Technology Expo (MTE), the gold medal at the 25th Archimedes International Invention Exhibition in Russia, the gold medal at the 48th International Exhibition of Inventions in Geneva, and the silver medal at the 74th Nuremberg International Invention Exhibition in Germany. 

Looking ahead, Professor Yi Guang-hui stated that the team will continue to develop natural plant compound essential oils with various benefits and promote them in more products, aiming to provide consumers with safer and more eco-friendly sun protection and skin care options.
