Possible Causes of Allergic Reactions

1. Chemical Components in Cutting Oil

Cutting oil consists mainly of mineral oil, synthetic oil, or semi-synthetic oil, with various additives such as antioxidants, preservatives, and emulsifiers. While these additives enhance cutting oil performance, certain chemical substances may irritate the skin and trigger allergic reactions.

2. Impact of Cutting Oil pH Levels

If the pH level of cutting oil is too high, it may cause corrosion in non-ferrous metal machining and pose a strong irritant to the skin. Conversely, if the pH level is too low, it may indicate bacterial contamination, leading to foul odors, bacterial growth, and increased risk of skin allergies.

3. Mist and Bacterial Contamination

During high-temperature machining, cutting oil may vaporize, producing mist that can be harmful to the skin and respiratory system. Prolonged exposure to these airborne particles may lead to skin allergies or respiratory irritation. Additionally, if cutting oil is not regularly replaced or cleaned, bacteria may breed in the oil tank, increasing the risk of skin infections.

Effective Measures to Prevent Cutting Oil Allergies

1. Choose Low-Allergen, Eco-Friendly Cutting Oil:

Some cutting oils contain formaldehyde, nitrites, and other harsh chemicals to enhance corrosion resistance, which can be primary causes of skin allergies. Selecting environmentally friendly cutting oils that have undergone safety testing, such as MORESCO and WILL AIE series cutting oils, exclusively distributed by Hai Lu Jya He, can significantly reduce the risk of skin allergies. These products feature antibacterial technology and are free from chlorinated compounds and other harmful chemicals.

2. Regularly Monitor Cutting Oil pH and Concentration:

Over time, cutting oil’s pH level may change, affecting skin health. Regular monitoring ensures the pH remains within the optimal range (typically 8.5-9.5) and helps maintain fluid quality by timely replenishing new oil.

3. Maintain Clean Equipment and Work Environment:

Accumulated oil residue and impurities in machines, tanks, and pipelines can promote bacterial growth, compromising cutting oil quality. Regularly cleaning oil tanks and replacing filtration systems can prevent contamination. Additionally, ensuring proper workplace ventilation helps reduce mist concentration and minimizes skin and respiratory irritation.

4. Use Proper Personal Protective Equipment (PPE):

Operators should wear oil-resistant gloves and long-sleeve workwear to minimize direct skin contact with cutting oil. It is also essential to regularly change gloves and avoid prolonged exposure to damp environments, which may weaken skin resistance and increase allergy risks.

5. Proper Skin Cleaning and Care:

After work, operators should wash hands with mild, neutral cleansers and warm water, avoiding abrasive or highly alkaline cleaning products that could damage the skin’s protective layer. Applying moisturizer after washing can help maintain healthy skin.

While cutting oil significantly enhances machining efficiency, improper long-term exposure may lead to skin allergies and health concerns. By choosing low-allergen, eco-friendly cutting oils, regularly monitoring fluid quality, keeping equipment clean, using protective gear, and adopting good personal hygiene habits, operators can effectively reduce the risk of cutting oil-related allergies.

Hai Lu Jya He recommends that all operators take a proactive approach when selecting cutting oils and maintaining workplace hygiene to ensure a safe and healthy working environment. For cutting oil-related inquiries or technical support, feel free to contact us for professional advice and solutions.
