How gene editing could reduce the cost of cosmetics
- Approximately 80% of cosmetic ingredients are currently sourced through unsustainable methods, with many traditionally extracted from animals or plants.
- Shark-derived squalene, a key skincare ingredient used in sunscreens and moisturizers, is estimated to require the annual killing of millions of sharks.
- The biotech company Amaris now supplies over 2,000 metric tons of lab-produced squalane, representing the majority of the global 2,500–4,000 metric ton market.
- Amaris utilizes synthetic biology to insert shark enzyme genes into yeast microbes, fermenting sugarcane to produce squalane; one square kilometer of sugarcane can replace the squalene of 3 million sharks.
- The industry faces a dichotomy where consumers demand animal-free products but often reject petrochemical alternatives while remaining unaware of the high land, water, and deforestation costs of plant-based sourcing (e.g., 200,000 rose petals for 5ml of oil).
- Currently, roughly 10% of global cosmetic ingredients are produced by gene-edited microbes, a figure expected to grow as costs decrease.
- Biotech firm Ginkgo has secured multi-million dollar contracts with major fragrance companies to develop scents via gene-edited microbes.
- Production timelines for viable microbial strains have shortened, with sequencing costs dropping a million-fold over the last decade, reducing the development cycle from months to potentially faster iterations.
- Fermentation-produced molecules can offer cost savings of up to 50% compared to traditional extraction methods, potentially lowering consumer prices.
- Regulatory environments in the US and EU currently favor this technology; the US lacks strict pharmaceutical-style oversight, while the EU distinguishes between the genetically modified organism (GMO) and the resulting nature-identical ingredient.
- Despite these advancements, the cosmetics industry faces independent environmental challenges, generating 120 billion units of single-use packaging annually and containing microplastics in nearly 90% of major brand products.
- Biotech companies are now exploring the use of engineered microbes to break down plastic waste, addressing the industry's packaging footprint.
- The cosmetics sector has become a critical market for synthetic biology firms following a value crash in other sectors like biofuels in 2021.
- Future outlook includes the potential to synthesize nearly every cosmetic molecule, including novel compounds currently inaccessible through natural extraction, driven by the industry's high-value tolerance for regulatory risk.
