The application of lemon flavor in hand cream

Abstract: Through access to relevant information literature, and get to the preliminary formula lemon essence formula and quasi Hand Cream. A number of experiments were carried out in the laboratory. To determine the basic formula of lemon flavor and hand cream. And then by adding or reducing the relevant raw materials and dosage on the basis of the continuous optimization of the formula. Get the final hand cream formula. The content of stearic acid 4%, oil content 8%, Brij721 content 3%, glycerol content 8%. And then make a delicate, smooth, skin feel better, meet the requirements of hand cream. Through repeated smells, fragrance, continuous improvement formula. Get the final lemon flavor recipe. The main raw material is the sweet lemon oil and lemon oil, the content is 30%, 45.8%. And then get the coordinate the aroma, fresh, sending, lasting, in accordance with the requirements of the experiment lemon flavor. Last, add the Lemon essence to hand cream. The relative optimum dosage of lemon essence was 0.3% by experiment.
