Steareth-4
Harm score: 4 (Slightly harmful chemistry)
Steareth-4 is a chemical that is most commonly used in cosmetic and industrial products. It is an emulsifier, meaning that it helps to combine ingredients that would not otherwise combine, such as oils and water. Steareth-4 is also known by the names Raspberry or Rubus Idaeus, although these names are often used to refer to raspberry or blackberry oil. The substance itself is made from vegetable or animal fats and oils by a precise chemical process.
In cosmetic products, Steareth-4 is used in a wide range of products, from creams and lotions to shampoos, conditioners and color cosmetics. Due to its emulsifying properties, it helps these products bind together better while softening their consistency. In some cases, it is also used in hair products to increase their foaminess. However, it can also be found in industrial products such as cleaning products or soaps, where it again serves as an emulsifier. Despite its widespread use, it must be stressed that manufacturers must adhere to the required concentrations when using this substance in order to achieve optimum product properties but also to ensure consumer safety.
