In an article co-authored with Greenology Products, Beta Analytic’s Marketing Manager Haley Gershon describes the use of Carbon-14 testing to verify biomass-derived ingredients used in the formulation of household and personal care products and explains the need of such testing to qualify for certain certification and eco-labeling programs.
The preference for plant-based household and personal care products has led manufacturers to develop biobased products. Carbon-14 testing is an appropriate and accurate method to verify biobased ingredients, since it measures the percentage of plant-sourced ingredients versus petrochemical-derived components in a product. Since Carbon-14 is a radioactive isotope present in all living organisms, any product derived from renewable sources will contain Carbon-14. On the other hand, fossil fuel-derived products do not contain any Carbon-14.
Carbon-14 test results are expressed in percentage (%) of biobased content ranging from 0% to 100%. A product that is entirely composed of renewable materials will yield a result of 100% biobased content. Whereas, a product that contains only petrochemical-derived substances will yield a result of 0%. A result in between these values indicates that the product is a mixture of biomass and fossil fuel-derived ingredients.

Greenshield Organic is a brand of Greenology Products that manufactures the first line of organic detergent and cleaning products in the USA. Greenology Products also offers organic and natural private label products in the home and personal care industries to retailers in the country.
The company has helped to bring more than 75 U.S. Department of Agriculture (USDA) Certified Biobased products to the market. With the objective of certifying those products, Greenology Products collaborated with Beta Analytic to perform the Carbon-14 testing on new formulations, not only to achieve the USDA Certified Biobased Product Label, but also to help confirm the formula ingredient derivation. Greenology products that have been tested include:
The company’s Organic Multi-Surface Cleaner Degreaser product achieved both USDA Certified 100% Biobased and USDA Certified Organic, which indicates that the product is wholly derived from natural ingredients and grown and processed organically in accordance with the USDA National Organic Program’s standards.
When it comes to certification, the percentage of biomass required will depend on the program. The USDA BioPreferred® Program, for example, establishes the minimum biobased content depending on a product’s category.
Examples of USDA Certified Biobased household and personal care products categories and their minimum biobased content requirements:
Carbon-14 analysis is a reliable method for determining the percentage of biobased content within a product formulation. Test results allow companies like Greenology Products to qualify for certain certifications, such as the USDA Biopreferred Program by validating if their products meet the required percentage of biobased content.
