Manufacturing and Evaluation of UV·Bluelight Blocking Effect of Cream Containing Spirulina Extract

The blocking of blue light is becoming important, as research has shown the adverse effects of blue on the skin. Chlorophyll, among the pigments contained in Spirulina, absorbs light at 400 to 500 nm and at 620 to 700 nm wavelengths. Since blue light is included in the area of light absorbed by the chlorophyll, the effects associated with blocking blue light can be expected using Spirulina. After manufacturing using titanium dioxide and spirulina to simultaneously block UV and blue light, sensory evaluation was conducted to compare blue light transmittance, measure viscosity, and measure usage. As for the blue light transmittance, spirulina was the highest at 10.94%. As a result of the UV measurement, 10% spirulina was found to be the highest at 35.05%. The result of the sensory evaluation found that Sample F was the highest for all items, except for stickiness.In conclusion, spirulina was judged to have blue light blocking effects. In addition, it was judged to be suitable a material for sunscreen that can provide antioxidant and anti-aging effects.
