Consumer perception of personal care products is changing in favor of those formulated with natural ingredients. The United States Department of Agriculture (USDA) has included personal care items like bath products in its BioPreferred Labelling Program, making it easier for consumers to identify which ones are significantly made of materials from feedstocks, agriculture or forestry. Biobased bath products certified by the USDA carry the BioPreferred label.
Biobased products certified under the BioPreferred Program have undergone third-party biobased content testing and validation. They can use the USDA biobased label on the product’s packaging and marketing materials.
Aside from the logo or artwork, the label also includes the biobased content percentage of the packaging material and the product, as well as the texts “USDA Certified Biobased Product“. The letters “FP” that appear on the label signify that the product is also part of the Federal Procurement Preference Program.
Under the BioPreferred Program, bath products cover personal hygiene products such as liquids, gels and bar soaps but excludes products marketed as hand cleaners or hand sanitizers. Body washes or cleansing lotions are included in this category.
Manufacturers who want their bath products to be certified under the USDA Biopreferred Program will need to make sure that the product is at least 61% biobased as measured by ASTM D6866 analysis. The USDA clarifies that a higher percentage of biobased content doesn’t necessarily indicate superior performance, safety, or environmental impact.
For bath products to be biobased, they may have surfactants, essential oils or fragrance and other ingredients sourced from biological materials.
Although each type has a different chemical composition, bath products all contain a surfactant as an active ingredient. Surfactants are traditionally petrochemical-sourced. Studies have noted that exposure to petrochemical-derived ingredients can cause skin irritation on the surface level and disrupt physiological activity internally. 1
Aside from health risks, waste from petrochemical-sourced surfactants can also be damaging to the environment. When waste is discharged in bodies of water, it stops productivity of aquatic plants and disrupts the balance of the food chain. When aquatic animals are eaten by humans, it increases internal concentration of surfactants in the body. 1
There are researches claiming that surfactants sourced from renewable sources are less harmful and exhibits cleaning efficacy comparable to the traditionally produced surfactants. Renewable resources may even come at a much lower production cost, proving it to be much more advantageous than its petrochemical counterpart. 2
The USDA BioPreferred Program aims to promote the purchase and use of biobased products that in turn increases economic development, provide more jobs, and direct new markets to needed commodities. As of 2014, the program’s economic impact includes $393 billion value added to the U.S. economy and 4.2 million jobs through direct, indirect and induced contributions. The BioPreferred Program currently has 97 product categories.
