Sun exposure can cause erythema and sunburn to cause degeneration of the skin such as premature aging and some skin cancers. Due to the negative effects of the sun's rays, we need to use a sunscreen skin protector. Natural materials for sunscreen preparations is commonly use because it is easy accept by the community. Sunflower seed oil is one of the natural ingredients that contains vitamin E which is as an antioxidant and also has the potential as a sunscreen. This study is purpose to determine the effect of adding sunflower seed oil to the effectiveness of a combination of oxybenzone and octyl methoxycinnamate sunscreen, determine the SPF (Sun Protection Factor) value, and determine the pH value of each cream preparation.The research includes the preparation of sunflower seed oil cream (Helianthus annuus), which consists of an in vitro test for SPF value, and pH test using a spectrophotometer UV-Vis. The results of the average SPF value of F1 (blank) is 8.24; F2 (blank + Oxybenzone 2% + Octyl methoxycinnamate 5%) is 21.26; F3 (1% sunflower seed oil) is 26.03; F4 (5% sunflower seed oil) is 26.84; and F5 (10% sunflower seed oil) is 28.88. In conclusion, this study result indicate that the addition of sunflower seed oil in various concentrations gives a significant difference in the increase of SPF values between each formula combined with oxybenzone and octyl methoxycinnamate.
