When we use fragrances on a daily basis, we often encounter some color problems. For example, some fragrances have no color, some are very dark, some fragrances have large color changes between batches, and some fragrances will change greatly over time. Here are some common color questions about daily chemical fragrances for you.
Why do fragrances have colors?
Flavor is usually composed of dozens to hundreds of fragrant raw materials, many of which are colored, especially some natural raw materials such as extract have a darker color, so many flavors will inevitably have color.
Why are the colors of different batches of the same type of essence different?
This is a relatively common problem in flavors, and it is also a relatively normal problem; flavors are mainly composed of two categories, synthetic flavors and natural flavors; synthetic flavors are relatively stable in color, but natural flavors, such as: orange oil, tangerine oil, lavender Oil and other natural essential oils, due to the large amount of impurities (pigments, etc.) brought into the raw materials, and the different years and origins, the color tends to be different. the probability will be greater.
Some flavors will change color during storage. What is the reason?
The color of the daily chemical essence often changes due to the change of time; one is that the color changes from dark to light, which is due to the addition of colored oils such as cold-pressed sweet orange oil, orange oil, and bergamot oil. Natural oil; since this type of essential oil is usually extracted by cold pressing, the extraction process often brings some natural pigments on the peel of this type of fruit into the natural oil, but such natural pigments are often not stable Under the action of factors such as oxygen, oxygen and other factors, the color will gradually fade away, and finally reach light yellow or even colorless.
