P2 Science Replaces Silicones and Petrolatum With Plant-Based Chemistry

Check the ingredients list on your moisturizer. Silicones. Petrolatum. Synthetic polymers derived from fossil fuels. They're in almost every product that feels good on skin—and they've been there for decades because nothing natural performed as well.

P2 Science changed that.

The Connecticut-based green chemistry company, founded by two Yale University scientists, builds plant-based ingredients that match or exceed the performance of synthetic compounds—without the environmental cost. Fast Company ranked P2 Science #2 in the beauty category on its 2026 World's Most Innovative Companies list for its breakthrough Citropol® F fragrance enhancer. Two weeks later, the company closed a $23 million oversubscribed funding round led by Sofinnova Partners to expand its green chemistry beauty ingredients platform beyond beauty into performance polymers, home care, coatings, and crop care. 

Why Synthetic Ingredients Dominated Beauty for Decades

Beauty formulations need specific physical properties. Silicones create slip and spreadability. Petrolatum locks in moisture and creates texture. Synthetic esters give skin care that smooth, non-greasy finish that consumers expect. No one switched to natural alternatives because natural alternatives didn't deliver the same performance.

That wasn't a chemistry failure. It was a manufacturing gap. The technology to convert plant-based molecules into high-performing cosmetic polymers didn't exist at industrial scale. Green chemistry existed in laboratories but not in supply chains that could serve brands manufacturing millions of units annually.

P2 Science was founded specifically to close that gap. Two scientists from Yale University, disheartened by the widespread use of non-sustainable synthetic compounds in everyday products, started P2 with one vision: develop high-performance ingredients that align with planetary health. Co-founded by Paul Anastas, PhD—the father of Green Chemistry who established the 12 Principles that define the field—P2 Science built its entire platform on those principles from day one. 

How the Citropol Series Actually Works

P2 Science's core innovation is process chemistry—proprietary reactor technology and manufacturing processes that convert abundant, renewable plant-based inputs into high-performing specialty ingredients at commercial scale.

Citropol polymeric emollients represent the first new category of liquid polymeric emollient since silicones arrived in cosmetics decades ago. They replace silicones and heavy synthetic esters in hair, skin, and color cosmetics—delivering the same slip, spreadability, and sensory finish without fossil-fuel feedstocks. The molecules are biodegradable and bioreintegrate after use rather than accumulating in waterways and soil.

Citropol F fragrance enhancer controls how volatile fragrance molecules release from a product over time. Fragrances fade because top and middle notes evaporate faster than base notes—the scent that smells perfect at application disappears within hours. Citropol F is proven to retain and extend top and middle fragrance notes, ensuring controlled release of volatile ingredients for long-lasting performance. The ingredient is derived from plant-based raw materials and biodegrades completely—unlike synthetic fixatives that persist in the environment.

Citrolatum P is a 1:1 plant-based replacement for petrolatum—one of the most widely used cosmetic ingredients globally. Petrolatum is a petroleum byproduct. Citrolatum P delivers identical functional performance—moisture retention, texture, spreadability—from 100% sustainable feedstocks. It's biorenewable, biodegradable, and biocompatible. Formulators swap it in without reformulating the entire product.

CitroVisc aesthetic enhancers replace silicone fluids with plant-derived alternatives delivering identical shine-enhancing properties across multiple viscosities. CitroSperse pigment dispersions use polycitronellol—a silicone-free plant-based emollient—as the dispersion medium for cosmetic pigments, making color cosmetics cleaner without sacrificing intensity or texture.

Validation From Industry's Most Demanding Standards

P2 Science was named to Fast Company's list of the World's Most Innovative Companies in both 2025 and 2026—consecutive recognition confirming the platform's sustained commercial relevance rather than a single breakthrough moment. The 2026 recognition specifically highlighted Citropol F's fragrance performance as representative of what green chemistry can deliver when designed for real-world product requirements.

P2 Science was selected for L'Oréal's €100 million sustainable innovation accelerator, L'AcceleratOR—arguably the most competitive validation available in global beauty. L'Oréal's selection process evaluates both technical performance and commercial scalability. Selection confirms that P2's ingredients meet the formulation standards of the world's largest beauty company.

The Cosmetics & Toiletries Allē Award recognized Citropol DE-4 in the Natural and Bio-derived Base Cosmetic Ingredient category. The $2.8 million ARPA-E federal grant funds AI-enhanced autonomous laboratory development to accelerate catalyst innovation—government recognition that P2's technology has implications beyond consumer products.

The $23 million round closed oversubscribed. New investors Emerald Technology Ventures and GS Futures joined alongside existing backers including Lewis & Clark Partners and dsm-firmenich ventures. Michael Krel, partner at Sofinnova Partners, stated directly: "P2 Science has demonstrated that green chemistry can compete on performance, not just sustainability credentials." 

What This Means for the Beauty Industry

The beauty industry faces regulatory pressure in Europe and consumer pressure globally to remove silicones, parabens, and fossil-fuel-derived ingredients from formulations. The challenge has always been finding alternatives that actually work. Natural ingredients with inferior performance don't solve the problem—they just create different products that consumers don't repurchase.

P2 Science's Citropol platform solves the performance problem. Brands replacing silicones with Citropol emollients don't reformulate downward. They maintain performance while meeting clean beauty requirements that were previously technically incompatible with each other.

P2 currently partners with brands and manufacturers in 25 countries. The new funding expands that reach into aroma technologies, performance polymers for industrial applications, home care formulations, coatings, and crop care—demonstrating that the underlying green chemistry platform has applications well beyond beauty.

CEO Oihana Elizalde described the milestone: "This validates the strength of our technology and the urgency of global demand for clean, scalable manufacturing solutions. We are positioned to supercharge our beauty business and bring real green chemistry solutions to entirely new industries."
