How Water-Based Engine Degreasers Are Made: Ingredients, Raw Materials, and Manufacturing Process

Water-based engine degreasers are cleaning solutions formulated primarily with water and surfactants (detergents or emulsifiers) to dissolve and remove grease, oil, dirt, and carbon deposits from engines and machinery.

Unlike solvent-based degreasers, they rely on surface-active agents (surfactants) to emulsify oil and grease, making them safer, environmentally friendly, and less flammable.

These degreasers are widely used in automotive workshops, industrial maintenance, fleet services, and eco-conscious facilities.

⚗️ Properties

• Water-Based: Main solvent is water; reduces VOCs and fire hazards.

• Environmentally Friendly: Biodegradable, non-toxic, and safer for workers.

• Effective Cleaning: Surfactants emulsify oils, grease, and carbon deposits.

• Mild to Medium Solvency: Less aggressive than petroleum solvents but safe on metals, plastics, and rubber.

• Versatile Application: Can be sprayed, brushed, or used in immersion cleaning.

• Residue Management: Rinses cleanly with water; minimal leftover film.

• pH Variants: Can be neutral, alkaline, or mildly caustic depending on strength.

🧪 Chemical Composition / Ingredients

Typical water-based engine degreasers contain:

1. Water: Main carrier and solvent.

2. Surfactants / Detergents:

   • Nonionic surfactants (mild, effective on oils)

   • Anionic surfactants (stronger grease removal)

   • Amphoteric surfactants (mild, pH stable)

3. Alkaline Agents (optional): Sodium hydroxide, potassium hydroxide for heavy grease.

4. Sequestering Agents: Bind metal ions, improving performance.

5. Corrosion Inhibitors: Protect cleaned metal surfaces.

6. Builders / Solubilizers: Enhance cleaning efficiency.

7. Fragrance / Colorants (optional): For user-friendliness.

🧰 Types of Water-Based / Surfactant Engine Degreasers

1. Mild / General-Purpose:

   • Neutral pH

   • Safe on all metals, plastics, and rubber

   • Suitable for light-to-medium engine grime

2. Alkaline / Heavy-Duty:

   • Higher pH (10–13)

   • Strong grease and carbon removal

   • Often used in industrial or fleet maintenance

3. Foaming / Aerosol Water-Based:

   • Ready-to-use spray

   • Generates foam for controlled application

   • Easier access to vertical or complex surfaces

4. Concentrated / Dilutable Formulas:

   • Sold in bulk

   • Diluted with water before use

   • Cost-effective for workshops and industrial cleaning

5. Bio-Based Water Degreasers:

   • Uses plant-derived surfactants or solvents

   • Fully biodegradable and eco-friendly

⚙️ How It’s Used

1. Dilute if required (for concentrates).

2. Apply via spray, brush, or immersion.

3. Let dwell for a few minutes to break down grease.

4. Scrub if necessary for stubborn deposits.

5. Rinse thoroughly with water.

6. Dry engine surfaces with compressed air or cloth.

⚗️ Production / Manufacturing Process

1. Raw Material Selection: Water, surfactants, alkaline agents, and additives.

2. Mixing: Combine water with surfactants under agitation until fully dissolved.

3. Additives: Introduce corrosion inhibitors, sequestering agents, and fragrances.

4. Quality Testing: Check pH, cleaning efficiency, stability, and foaming properties.

5. Packaging: Bottled, jerrycans, or bulk containers depending on end use.
