The objectives of this study were to find for suitable chemical reagents to use as a green-color protector for Gardenia jasminoldes Green pigment and to compare the effectiveness of these reagents for discoloration prevention. Gardenia jasminoldes Green treated with polyoxyethylene (POE) (12) dimethicone shouted a greener color than those treated with methoxycinnamidopropyl hydroxysultaine ultraviolet stabilizers after ultraviolet radiation (UVR). The experimental results exhibited that the concentration of the POE (12) dimethicone affected the effectiveness of green-color conservation. The greenest rotor was obtained by treating 0.10 wt% aquous solution of Gardenia jasminoldes Green with 1.0 wt% POE (12) dimethicone aqueous solution and the absorbances of the solutions after UVR were increased from 78% to 95% in comparison with the untreated. In addition, the Gardenia jasminoldes Green aqueous solution mixed with POE (12) dimethicone showed great green-color fastness in outdoor weathering exposure. The mechanism of the green color protection under UVR is unclear, however the dimethicone group of POE (12) dimethicone may play and important role in the stabilization.
