The role of stearic acid in pest control

Stearic acid sourced from palm fruits

Today, we’re delving into a not-so-talked-about hero in the realm of non-toxic pest control—stearic acid. You might be familiar with stearic acid as a component in various products, but did you know it plays a crucial role in disrupting the life cycles of pests, offering a safer alternative to traditional chemical pesticides? 

Let’s uncover how this simple yet effective ingredient is making strides in our continuous battle against pests.

Understanding stearic acid

Stearic acid is a versatile saturated fatty acid that's widely used across various industries due to its beneficial properties. Found naturally in animal and plant fats, the stearic acid used in Dust to Dust is sourced from palm oil. Other common sources for stearic acid include cocoa butter and animal tallow. This waxy solid is employed in soaps, cosmetics and detergents due to its ability to harden and thicken products.

Benefits of stearic acid in environmental safety

Stearic acid is a key component in Dr. Killigan’s Dust to Dust Plant-Powered Insect Powder, chosen for its compatibility with our environmental and safety values. 

Here’s how it makes our products safer for users and the environment:

  • Non-toxic formulation: The stearic acid in our product is derived from palm sources. It is non-toxic and safe to use around your family and pets.

  • Protection of active ingredients: Stearic acid creates a protective matrix around the essential oils and other active ingredients in our products, providing two key benefits:
    • Prevents premature degradation: Ensures that the active ingredients—such as encapsulated peppermint and rosemary oils—remain effective longer, resisting breakdown from environmental factors such as light and air exposure.
    • Enhances efficacy: The silica acts as a carrier, working in conjunction with stearic acid, which forms a matrix for even application of the active ingredients. This combination ensures that the essential oils are distributed uniformly, enhancing their effectiveness against pests. The effects vary depending on the type of insect and exposure.

  • Enhanced user experience: The structure formed by stearic acid prevents clumping and ensures easy application. Users benefit from a product that spreads evenly and effectively, without the hassle of dealing with lumps or uneven distribution.

  • Regulatory compliance and safety: Dr. Killigan's prioritizes safety and stringent compliance in our pest control solutions. Our use of stearic acid aligns with the U.S. Environmental Protection Agency’s (EPA) guidelines for "minimum risk pesticides." These substances are recognized by the EPA as posing little to no risk to human health or the environment, exempt from federal registration but rigorously assessed for safety. 

Case study | Proven effectiveness against pests

Dr-Killiigans-Dust-to-Dust

Research in 2022 highlighted the power of stearic acid in combating pests like the sugarcane aphid—a major agricultural threat. The study demonstrated a 74% mortality rate within 72 hours when aphids were exposed to stearic acid, making it an effective, eco-friendly alternative to synthetic insecticides.

Stearic acid, along with other fatty acids, disrupts the pest’s life cycle by damaging essential proteins and enzymes, reducing their survival rates significantly. This positions stearic acid as a potent natural solution for sustainable pest control.

By incorporating stearic acid into Dust to Dust, Dr. Killigan’s provides a scientifically backed solution for tackling common household pests while minimizing environmental impact.

Conclusion

The role of stearic acid in pest control illustrates how traditional ingredients continue to be fundamental in solving modern problems. At Dr. Killigan's, we are proud to incorporate such elements into our products, ensuring they are safe, effective and environmentally friendly. Our commitment to sustainability and effectiveness is reflected in every bottle, backed by the power of nature and science.
