Special silicone oil for the food and pharmaceutical industries strictly complies with national food safety and pharmacopoeia standards. Relying on its physiological inertness, non-toxicity, non-irritation, and rapid defoaming properties, it has become an indispensable raw material for food processing and clinical medical treatment. The market growth rate of this niche segment has remained stable at over 10%.

In the food processing scenario, food-grade dimethyl silicone oil is widely used as a compliant defoaming agent. During processes such as soybean paste boiling, sugar production, juice fermentation, and beer brewing, a large amount of foam is easily generated, causing material overflow and loss of raw materials, as well as interfering with production. A small amount of silicone oil can quickly break and suppress the foam, without changing the original flavor of the food. In baking and chocolate production, silicone oil is used as a demolding agent, with stable high-temperature performance and no precipitation, meeting the safety standards for food contact materials. In the refining of edible oil and canning processing, silicone oil is also used to eliminate foam, improving processing efficiency.

In the pharmaceutical field, dimethyl silicone oil is included in the pharmacopoeia and is a commonly used functional auxiliary material. Oral administration of dimethyl silicone oil tablets for gastrointestinal distension and indigestion can quickly dissolve gas bubbles in the digestive tract, alleviating abdominal distension discomfort; before gastrointestinal and abdominal imaging examinations, taking silicone oil can eliminate intestinal foam, improving image clarity; adding silicone oil as a base material in external ointments can make it thin and easy to apply, forming a breathable protective film on the skin, isolating acid and alkali, sewage stimulation, and assisting in the repair of dermatitis and chapped wounds.

In medical device processing, high-purity silicone oil is used for lubrication of urinary catheters and puncture instruments coatings to reduce mucosal friction discomfort; the inner wall of blood storage containers is coated with silicone oil to inhibit blood coagulation and extend the storage period of blood samples; medical beauty repair dressings and scar patches use medical cross-linked silicone oil, which has strong biocompatibility and no rejection reaction when in contact with the human body.

Industry experts suggest that industrial silicone oil cannot be used in food and pharmaceutical production. Special grade products with strict control of heavy metals and ring body residues must be selected. With the standardized development of the food processing and medical beauty industries, the production capacity of high-purity medical and food-grade silicone oil continues to expand, significantly reducing the procurement costs for downstream enterprises.
