Need an Effective D-Limonene Alternative?

Sta-Sol® ME products offer proven d-Limonene alternatives for degreasing and cleaning applications.

D-Limonene is used as a degreasing and cleaning solvent in many soil and resin removal applications.

Formulators and end-users of straight d-Limonene find it very effective in attacking hydrocarbons such as oils, grease, tar, asphalt and fuels.

D-Limonene has also been labeled as a “green” solvent due to its natural and renewable origins (citrus peels) and biodegradability.

However, because of worker safety concerns (i.e. vapors and flammability), increasingly strict consumer product regulations concerning volatile organic compounds (VOCs), price fluctuations in the citrus crop and unpredictable availability, many formulators have been looking for an effective way to reduce or replace d-Limonene in their products.

The Challenge: Finding a suitable d-Limonene Alternative

Replacing d-Limonene, or offsetting its usage in a cleaning formulation, presents a unique set of challenges.

For example, an effective alternative would need to meet the solvency needs and performance expectations of d-Limonene users.

A suitable d-Limonene alternative should be an ingredient that also reduces environmental, health and safety concerns, while offering price stability and reliable availability.

Why Sta-Sol® Microemulsion Concentrates?

Sta-Sol® ME concentrates are proven extenders or substitutes for d-Limonene in several cleaning and degreasing applications.

Sta-Sol® ME products are designed to provide maximum flexibility for formulators and end-users. They are clear, thermodynamically stable, single phase solutions of alternative solvents and surfactants.

These water-dilutable ingredients offer a cost-effective and efficient way to enhance product performance in smaller concentrations.

Sta-Sol® ME products are compatible with d-Limonene, so they can be used to reduce the amount of d-Limonene in a given formulation, or completely replace it.
