Lipstick is made up of three main ingredients: wax, oil and colorant. Depending on the content and origin of the ingredients, the lipsticks produced have different colors, smoothness and safety.
Lipstick is a commonly used cosmetic.
Wax
This is the ingredient that creates the hardness of the lipstick. Some of the waxes commonly used to make lipstick include beeswax, Carnauba wax, Candelila wax and lanolin wax, hydrocarbons such as paraffin, ozokerite.
Oil
Oils have the effect of moisturizing, creating smoothness and dissolving colorants or other soluble substances in lipstick. The most commonly used oil in lipstick production is castor oil. In addition, there are grape seed oil, almond oil, palm oil, olive oil, cocoa butter, jojoba, linolin, IPM, IPP, mineral oil, vegetable oil...
Colorant
Colorants help give color to lipstick and are divided into two types: inorganic colorants and organic colorants.
Inorganic colors commonly used such as iron oxide, TiO2, ZnO, pearl powder are insoluble, so appropriate preparation techniques are required to evenly disperse the color.
Organic colors such as beetroot red, Anthocyanins, Lactoflavin are soluble, easy to disperse evenly but cause color smudging. Therefore, they are often combined together to create lipsticks that do not smudge but have even color.
Besides the 3 main ingredients, some lipsticks also have the following ingredients:
Nowadays, there are many colors and varieties of lipsticks on the market.
Preservatives
Cosmetics always need preservatives. These substances help maintain the shelf life of lipstick because the ingredients will oxidize over time. On average, a lipstick can only be used for 1 year, when preservatives and antioxidants are added, it can be used for a longer time.
Antioxidants
Antioxidants are added to prevent oils and waxes from going rancid. Some common antioxidants are vitamin E (tocopherol), BHA or BHT.
Flavoring agent
Artificial fragrances are often used to mask the scent of chemical ingredients in oils, waxes and colorants in lipstick. People with dry, chapped lips should limit the use of scented lipsticks because they can cause skin irritation.
