| Summary: | Nowadays, sago starch has been used by peoplenormally for food industry. The <br />
<br />
utilization of various sago starch depends on the needs and it has been proven that <br />
<br />
sago starch can be used as a cosmetic formulation. This study aims to utilize sago <br />
<br />
starch as talc substitute in compact powder formulation that has high covering <br />
<br />
effect and evaluation of its sunscreen activity. The study begins with the <br />
<br />
characterization of sago starch and then its reduced the particle size of sago starch <br />
<br />
using tumbler ballmill.After milling the sago starch powder, it characterized base <br />
<br />
on its particle size, particle morphology using SEM, and evaluation of powder <br />
<br />
physics. The particle size is 17,7 ± 0,046 μm. Sago starch with various <br />
<br />
concentration of 65, 75 and 85% is added kaolin as filler, PVP as binder agent, <br />
<br />
titanium dioxide and zinc oxide are as a comparison sunscreen. The sunscreen <br />
<br />
activity was previously determined using Xenon Weather-Ometer instrument and <br />
<br />
blue wool fabric as measurement standard of fading time. Irritation test and SPF <br />
<br />
determining as in vivo evaluation using albino male rabbit and UVB handheld <br />
<br />
lamp. The result showed no irritation skin and F2A formula (sago starch 75%) had <br />
<br />
protection ability toward solar simulator is more optimal than F1A and F3A <br />
<br />
formula with SPF value is 3,81 on F2A formula. Whereas in the formulation of <br />
<br />
compact powder added with sunscreen agent like titanium dioxide (F2B) showed <br />
<br />
the result of protection ability toward solar simulator is more optimal than F2B. <br />
<br />
SPF value on F2B formula is 11,64. Formulated compact powder from sago starch <br />
<br />
had sunscreen activity. |
