Abstract

Corn cob is the important type of agriculture residue. It contains phenolic compounds, protein, carbohydrates. We prepared and evaluated sunscreen lotion containing corn cob extract. Corn cob was extracted with reflux method using ethanol 80% for 8 hours. Several lotion containing 5% (F1), 7.5% (F2), and 10% (F3) extract was designed. These lotions were subjected to physical studies such as pH, viscosity, spreadability, adhesivity, organoleptic, and stability. The sun protection factors (SPF) were analyzed by ultraviolet (UV) spectrophotometry using samples irradiated with UV in B region. The results showed that the extract and formulations have minimum sunscreen protection. The extract showed SPF value was 4.95±0.86. The adding of corn cob extract in the lotion resulted in increasing SPF value of formulation. SPF values of F1, F2, and F3 were 1.20±0.06; 2.17±0.31; and 3.01±0.13, respectively. The formulation of sunscreen lotion containing corn cob extract meets the requirements of physical properties. The formulation containing 10% extract (F3) has the most effective sunscreen lotion. It showed the dark brown lotion with pH 7±0, viscosity 5244±20 cp, spreadability 5.06±0.02 cm, and adhesivity 1.0±0.04 s.
