Lactate Solvents: A Smarter Approach to Sustainable Formulation
Across industries such as coatings, inks, adhesives and industrial cleaning, formulators are under increasing pressure to reduce environmental impact while maintaining the performance standards their customers expect.
For many years, solvent selection was primarily driven by technical considerations such as solvency power, evaporation rate and formulation compatibility. Today, the decision-making process has become far more complex. Manufacturers are expected to reduce the carbon footprint of their products, increase the use of renewable raw materials, improve safety profiles, limit emissions and support circular economy initiatives while complying with evolving regulatory requirements.
For formulators, the challenge is therefore no longer simply finding a sustainable solvent, but identifying the solution that best balances technical performance, environmental impact and regulatory expectations for a specific application.
Among the various sustainable solvent technologies available today, lactate solvents are attracting growing attention because they successfully address several of these requirements simultaneously. Derived from bio-based lactic acid, they combine renewable sourcing, biodegradability, strong solvency performance and broad formulation versatility, making them an increasingly attractive option for companies seeking more sustainable formulations.
Where Lactates Create Value for Formulators
Combining Sustainability and Performance
One of the main reasons formulators choose lactates is that they do not have to sacrifice performance to improve sustainability. Produced from bio-based lactic acid obtained through fermentation processes, lactates offer a renewable alternative to many traditional petroleum-derived solvents. At the same time, they deliver strong solvency performance that makes them suitable for demanding industrial applications.
Their solvency profile allows them to dissolve a broad range of materials and resins, making them effective solvents for coatings, inks, adhesives and numerous specialty applications. They can perform similarly to, and in some cases replace, conventional solvent technologies including glycol ethers, chlorinated solvents, ketones and certain hydrocarbon solvents.
Supporting Environmental Goals
Because they are derived from renewable raw materials and are readily biodegradable, lactates help manufacturers improve the sustainability profile of their formulations. Compared with conventional petroleum-based solvents, they can contribute to reducing overall environmental impact while supporting corporate sustainability objectives.
For companies seeking to increase renewable content while maintaining formulation efficiency, lactates represent a practical and proven solution.
Enabling Safer Solvent Substitution
Many industrial sectors are currently reviewing existing formulations to identify safer alternatives to traditional solvents. Lactates are increasingly considered during these substitution projects because they offer a favorable combination of performance and safety. Their high flash points and lower volatility contribute to a more comfortable working environment while maintaining cleaning or formulation performance.
A Valuable Evaporation Profile
Another distinctive characteristic of lactate solvents is their relatively high boiling point and slow evaporation rate. While highly volatile solvents may be preferred for certain processes, slower-evaporating solvents can provide important benefits in coatings, inks and industrial cleaning applications. Longer working times, improved wetting characteristics and enhanced film formation are often desirable when developing high-performance formulations.
Key Applications for Lactate Solvents
The combination of strong solvency power, biodegradability and formulation versatility explains why lactates are used in an increasingly diverse range of industries.
In coatings, paints and inks, lactates are used both as solvents and formulation aids. Their solvency profile and evaporation characteristics make them particularly suitable for resin-based systems where performance and sustainability must coexist.
Industrial cleaning is another major application area. Lactates are used for metal cleaning, surface cleaning, printing press cleaning and even paint stripping applications thanks to their ability to remove oils, greases, inks, waxes and other difficult contaminants. Their strong cleaning performance, combined with an improved environmental profile, makes them attractive alternatives to more conventional cleaning solvents.
In agrochemical formulations, lactates can function as solvents and formulation aids. Their excellent solvency and wetting characteristics can help improve the effectiveness of active ingredients while supporting the development of more sustainable products.
The electronics industry also represents a significant area of opportunity. Lactates have demonstrated value in semiconductor manufacturing, printed circuit board cleaning and other specialized electronics applications that require high-purity solvents with strong performance characteristics. Additional opportunities continue to emerge in personal care formulations, green extraction processes and other applications where sustainability and performance are equally important.
