21. Draw up a technological scheme of the main stages of perfume production. Determine parameters for assessing the quality of perfumes.
With the use of essential oils and alcohol, you can get toilet or perfumery water and spirits. Receipt process such perfumery products include the following stages: - preparation of a perfume composition; - obtaining a perfume liquid (dissolving a perfume composition in alcohol, adding water and dyes if necessary);
– aging of perfume liquid (maturation) for obtaining the necessary smell; – filtration to remove sediment; – bottling, capping, design and packaging of products.
The technology of perfumes includes the following stages:
- dosing of the components included in the formulation;
mixing components; liquid settling;
filtration; packaging, packaging, labeling of the finished product.
Quality control of perfumery products
Evaluation of the quality of perfume compositions and base compositions and fragrances is carried out according to the following indicators in accordance with the requirements of TC 64-19-68-90 and TC 64-19-149-92: appearance; color; smell; refractive index;acid numberTest methods
1.the appearance of the perfume product is determined by examining the bottle together with the product at a distance of 20 cm from the lamp and 40 cm from the Observer, when the bottle is turned with the cork down, in the passing light of an electric lamp.
2..the strength of perfume liquids (conditional) is determined by the alcohol meter at 20 OC. It is allowed to determine the concentration of alcohol by density. 3.the sum of the mass fraction of aromatic substances is determined by gravimetric method.
22. Draw up a technological scheme for obtaining perfume liquids. Define parameters for quality assessment.
Парфюмерлік сұйықтықтарды алудың технологиялық сызбасын құрастырыңыз. Сапаны бағалау үшін параметрлерді анықтаңыз.
To prepare perfume liquids, we need such products as: concentrate, alcohol, water and emulsifier.
the process is done in this way we prepare the raw materials using scales, weighing the volume we need
Then we add raw materials and complementary minor ingredients such as for the smell, color and appearance of our product. This product consists of essential oils 5%, ethyl alcohol 15%, purified water 79%, and emulsifiers 1%
Then everything goes according to the old scheme: label, packaging, marking, date and application. storage in an airtight container
