WHAT DO ALL THE INGREDIENTS ON THE LABEL OF COSMETICS MEAN?

Thanks to the ingredients listed on the labels of cosmetics, we can understand the quality of the product as well as identify certain ingredients we are allergic to.
Typically, the ingredients are arranged according to the amount contained and the most important ones are the first 4/5. This description of components follow the international standard INCI (International Nomenclature of Cosmetic Ingredients), that could be European (INCI EU) or American (INCI USA). For this reason, in many products there is a double description, such as “Aqua (Water)”. Only plant substances are expressed with their Latin botanical name ("borado officinalis seed oil" ), while those that have undergone a chemical process are indicated in English (“sodium laureth sulfate”).
Also we can differentiate ingredients by being careful about the name itself. Here a little explanation:
- PERFUMES AND FLAVOURINGS are indicated on the label with the terms "Parfum" or "Aroma".
Nowadays there is also a list of 26 POTENTIALLY ALLERGENIC SUBSTANCES that must be indicated on the label, usually they are found especially in perfumes.
- BOTANICAL SUBSTANCES OR PLANTS DERIVATIVES are indicated on the label with the botanical name (genus and species) followed by the indication in English of the part of the plant and the type of derivative:
Example: lavender essential oil " Lavandula Angustifolia Oil " / aloe juice " Aloe Barbadensis Leaf Juice"
- the same applies to PLANT EXTRACTS, example: glyceric extract of Calendula flowers "Glycerin (solvent), Aqua (solvent), Calendula Officinalis Flower Extract (name of the plant)"
