What Is Copolymer of Acrylic—and Why Is It Used?

If you’ve ever come across “copolymer of acrylic” on an ingredient list and been a little confused, you’re not alone. It’s not immediately clear what role it plays in a formula, and once you find out—it still doesn’t feel entirely necessary. 

What Is Copolymer of Acrylic?

Copolymer of acrylic is a synthetic material made by combining acrylic-based compounds with other components. In the simplest terms, it helps control how ingredients move within a formula, keeping particles from clumping, separating, or settling over time. Many conventional products use acrylic copolymers for this purpose, but they are not the only way to achieve consistent performance.

You’ll typically find it in a range of products—from household cleaners to personal care—when stability matters for formulation: 

• Household cleaners and dishwashing products

• Laundry detergents

• Personal care products like shampoos and conditioners

What Does Copolymer of Acrylic Actually Do?

Its primary role is to keep particles evenly dispersed. During a laundry or dishwasher cycle, particles like dirt, minerals, or even other formula components are constantly shifting. Some conventional formulas use acrylic copolymers as a stabilizer to prevent these particles from settling or redistributing unevenly. In some cases, it can also help reduce streaking. 

There are several different kinds of stabilizers—some synthetic, some natural. Many conventional formulations opt for synthetic stabilizers like copolymer of acrylic, whereas brands like Blueland choose to formulate with a natural stabilizer. Natural stabilizers are equally as effective without contributing to microplastic pollution.  

Is Copolymer of Acrylic Plastic?

Short answer—yes. Copolymers of acrylic are synthetic polymers, typically grouped within the broader category of plastics due to their chemical structure and durability.

They’re engineered to remain stable in solution, meaning they resist breaking down under typical conditions like changes in temperature, pH, or water composition.  

That also means they don’t break down easily after use and can re-enter our water systems and environment as microplastic particles. 

At Blueland, we prefer to think more intentionally about what actually needs to be in a product and what doesn’t. Our formulas are created 100% microplastic-free without sacrificing stability or a powerful clean. No copolymer of acrylic necessary. 

Key Takeaways

• Copolymers of acrylic are synthetic polymers used to help stabilize formulas and improve performance.

• In some products, similar polymers can also influence how surfaces look after cleaning.

• They’re widely used, but are not readily biodegradable.
