Pharmaceutical-Grade Paraffin Oil Is Used in Pharmaceutical Equipment and Clean Production

1. Parameters

(1). Basic physicochemical parameters

Appearance: Colorless, transparent, non-fluorescent

Odor/Taste: Odorless, tasteless

Chemical composition: Highly refined saturated hydrocarbons (C15–C40)

Aromatic hydrocarbon content: ≈ 0 (strictly controlled)

Sulfur, nitrogen, and oxide content: Not detected or extremely low

(2). Viscosity parameter (40 °C)

Common grades:

Viscosity: 15–25 cSt (light)

32–68 cSt (medium)

100–150 cSt (high viscosity)

Viscosity Index (VI): ≥ 90

(3). Safety and Stability

2. Core Characteristics of Pharmaceutical Grade Paraffin Oil

(1). Extremely high purity and safety

Deep de-alkylation, de-sulfurization, and hydrofining

Free of carcinogenic polycyclic aromatic hydrocarbons (PAHs)

Can be in direct or indirect contact with the human body

(2). Chemically inert

Does not react with acids, bases, or drug active ingredients

Does not affect drug stability or formulation performance

(3). Good physiological compatibility

Not absorbed by the human body (for external use/intestinal use)

Non-irritating and non-sensitizing

(4). Excellent stability

Antioxidant, not easy to discolor or age

Does not decompose or change flavor during long-term storage

3. Application scenarios (typical applications)

(1). Medical consumables

Lubrication of syringe pistons

Processing aids for medical rubber and plastic products

(2). Pharmaceutical Equipment and Clean Production

Lubrication of Tablet Presses and Filling Machines

Pistons, Rails, Sliding Components

Low-Pollution Lubrication in Clean Rooms

(3). Food and Health Products (Indirect Contact)

Food machinery lubrication (NSF H1 grade)

Candy, anti-sticking coating

Capsule polishing agent

(4). Cosmetics and Personal Care

Baby Oil

Skin Cream, Moisturizer
