Other ingredientsBody wash formulas

Other ingredientsBody wash formulas contain additional ingredients that act as formulation and stability aids. The addition of polymers and salt alter a product’s viscosity, which can modify per- formance characteristics or improve physical stability. Feel modifiers such as silicones are sometimes used to improve the in-use tactile properties of body washes that deposit lipophilic benefit agents on skin. Chelating agents such as ethylenediamenetetraacetic acid (EDTA) and antioxidants such as butylated hydroxytoluene (BHT) and are added to improve chemical stability, and buffering a body wash formula to a specific pH value can help inhibit microbial growth and improve the product’s chemical and physical stability.Color and fragrance are an important part of the in-use experience for many body washes. Colors are US Food, Drug, and Cosmetic Act (FD&C) approved dyes and are usually present in relatively low amounts, so the likelihood of experiencing an issue with a body wash product because of dye is low. Fragrances are also usually present in relatively low amounts, although the apparent concentration may seem higher as a result of “bloom” that results from lathering a body wash on a mesh cleansing puff, the recommended application procedure for many of these products. The inci- dence of issues with modern fragrances is low. Some body washes incorporate natural oils to impart fragrance but these products are not necessarily without potential issues because some of these natural materials can cause sensitization.
