Although the palette of green materials available for beauty product development has widened in recent years, Organic Monitor finds beauty product formulators and developers still face many technical and sustainability issues when using natural ingredients.
Preservation remains the number one technical hurdle for developers of natural and organic personal care products. Although many green materials have become available for preservation, no single material is popular because of variations in product composition.
Stability also is a major issue, with some green preservative systems leading to discoloration and/or odor changes. Green surfactants are another problematic area, partly because certification agencies cannot agree on permissible green chemistry processes.
However, most progress has been made in the area of green emulsifiers and rheology modifiers. Organic Monitor finds that many ingredients are now available to produce elegant skin care emulsions.
Another major development in this area is the move from producing green materials to the use of sustainable processes and extraction techniques. A number of ingredient companies are investing in new processing techniques and sustainable technologies. For instance, the Zeta Fraction technology of AkzoNobel enables natural actives to be harvested from plant materials with a lower environment impact than traditional methods. Mibelle Biochemistry is using plant stem cell technology to extract actives from plants, and its PhytoCellTec technique allows active ingredients to be extracted from rare and exotic plant species in a sustainable manner.
The move toward green raw materials and sustainable processing methods is partly driven by leading operators. L’Oréal and Natura Brasil, two of the largest cosmetic companies in the world, have made commitments to reduce their environmental footprints by the use of green formulations. In fact, L’Oréal has pledged to only use new beauty and cosmetic ingredients that have a lower environmental footprint then existing ones.
As will be shown at upcoming editions of the Sustainable Cosmetics Summit, the environmental impact of green materials is not always easy to measure. Beauty product developers may wish to replace synthetics with green materials, however the move can have unintended consequences on ecosystems. For example, palm oil, the most widely used vegetable oil in cosmetic applications, has been responsible for the destruction of tropical rainforests in Southeast Asia, and questions also hang over the sustainable sourcing of many natural fragrances, as well as the growing use of food ingredients in cosmetic applications.
While beauty formulators and product developers maybe slowly getting to grips with the technical issues associated with green materials, Organic Monitor believes the sustainability issues are likely to persist for many years yet.
Green formulations are a focal theme of the upcoming European and Asia-Pacific editions of the Sustainable Cosmetics Summits, which will take place on October 21–23, 2013 in Paris, and in Hong Kong on November 11–13, 2013, respectively. Each summit will have dedicated sessions and workshops on green materials, formulations and product development.
The Cosmetics & Toiletries Complete Cosmetic Chemist Training Program offers an online, video-based course dedicated to teaching new and seasoned formulators about natural formulation and how to choose genuinely natural or organic products.
Registration for this course also includes a free copy of Anthony C. Dweck's book, Formulating Natural Cosmetics.
