Physical and Chemical Properties | Clear essential oil colorless or light yellow to yellow-brown. With such as rose and geraniol characteristic of the sweet aroma and mint breath, there is a bitter taste. Unstable to strong acids, geraniol esters and citronellol esters are partially saponified in alkaline. Soluble in ethanol, benzyl benzoate and most vegetable oils, mineral oil and propylene glycol often milky white, insoluble in glycerol. |

colorless or light yellow to green yellow clear transparent liquid, with a characteristic sweet aroma such as rose and geraniol and mint cool breath, with bitter taste. Soluble in ethanol, benzyl benzoate and most vegetable oils, mineral oil and propylene glycol often milky white, insoluble in glycerol.
The fresh branches and leaves of Geranium Geranium, a plant of yak seedling family, were cut, and the oil was extracted by steam distillation.
It is mainly used for the preparation of perfume, soap, Essence, toilet water, cosmetics and other daily chemical products. It can also be used in food, tobacco and alcohol flavors.

content analysis | acid value accurately weigh about 5g of the sample and measure it according to OT-4. However, 15ml of water instead of ethanol should be used, and the titration should be continuously stirred to maintain the turbid state. Ester values after acetylation were determined by total alcohol determination (OT-5). When saponification, The acetylated oil is accurately weighed about 1.9g. The Ester value (z) after acetylation is calculated according to the following formula: x = A x 28.05/B where A -0.5mol/L consumed upon saponification. Number of ml of potassium hydroxide ethanol solution; B- weight of acetylated oil, g. |
toxicity | LD50>5.8g/kg (mouse);>2.5g/kg (rabbit). GRAS(FDA,§ 182.20,2000). |
Use | flavorant. Mainly used for the preparation of tobacco, wine and food flavor. is one of the important natural spices, widely used in the deployment of perfume, soap, cosmetics and other daily chemical products, can also be used in a small amount of edible, tobacco flavor. as a food spice, mainly used in tobacco, wine and other food flavors. 8.1mg/kg in chewing gum; 6.9mg/kg in baked food; 5.2mg/kg in candy; 2.8mg/kg in jelly; mg/kg in cold drinks; 1.6mg/kg in soft drinks; 1.1~2.0mg/kg in pudding. |
method of production | originated in Morocco, Algeria, introduced in the southwest and east China, the fresh stems, leaves or the whole plant of the plant geranium of bovine seedling family are used as raw materials, and the oil yield is 0.1% ~ 0.3% by steam distillation. obtained by steam distillation of fresh stems, leaves or whole plants of Pelargoniun graveolens or P. Rosenum and P. Terebinthacaceum. The yield was 0.1%-0.3%. It is mainly produced in the island of La La Réunion, Morocco and Algeria, and cultivated in the southwest and east China. |
