Phenyl silicone oil does not belong to the category of food-grade lubricants. It is usually not directly used in the food industry and is not approved as a lubricant for food contact materials or food processing equipment. The following is an explanation from three aspects: safety, regulatory compliance and alternatives:

1. Safety issues of phenyl silicone oil
Phenyl silicone oil is an organic silicon compound that is usually used in industrial fields such as electronics, machinery, and chemicals. Its chemical structure and properties make it stable under high temperature, high pressure or specific chemical environments, but these characteristics do not meet the safety requirements of food-grade materials. Food-grade lubricants need to meet strict food safety standards to ensure that no harmful substances are released when they come into contact with food, while phenyl silicone oil may contain ingredients that are harmful to the human body, such as unreacted raw materials, catalyst residues or degradation products. If these substances migrate into food, they may cause harm to health.

2. Regulatory compliance restrictions
In the food industry, the use of lubricants is subject to strict regulatory supervision. For example, the U.S. Food and Drug Administration (FDA) and EU food regulations (such as EC No. 1935/2004) have clear regulations on food contact materials and lubricants, requiring that their ingredients must be safety evaluated and approved. Phenyl silicone oil is not included in the approved list of these regulations and therefore cannot be used for lubrication of food processing equipment or in direct contact with food.

3. Alternatives to food-grade lubricants
Lubricants designed for food contact are commonly used in the food industry. These lubricants are made of ingredients that meet food safety standards, such as white mineral oil, synthetic hydrocarbons, or specially treated vegetable oils. They are rigorously tested to ensure that they will not contaminate food in food processing environments. For example, NSF H1 certified lubricants are specially designed for food processing equipment and meet food safety requirements.

4. Risks and responsibilities
The use of unapproved lubricants (such as phenyl silicone oil) may lead to the following risks:

Food contamination: Lubricants may migrate into food, resulting in chemical residues.
Legal liability: Violation of food safety regulations may result in fines, product recalls, and even legal proceedings.
Reputation damage: Food safety issues may seriously damage the corporate brand image.

5. Recommendations
To ensure food safety and compliance, food processing companies should:
Choose certified food-grade lubricants: such as NSF H1 certified products.
Follow the supplier's instructions: ensure lubricants are used correctly to avoid cross contamination.
Check equipment lubrication regularly: prevent lubricant leakage or overuse.
Train employees: improve awareness of food safety and lubricant use.
