Product Description
Vaseline is a white, yellow, or light amber semi-solid substance, almost odorless and tasteless. It is a mixture of liquid and solid paraffin hydrocarbons. Vaseline is insoluble in water, but soluble in ether, petroleum ether, benzene, and some oils. It is non-corrosive, pH-neutral, and does not exhibit alkaline properties. When spread thinly, it appears transparent and can show slight fluorescence under UV light. Vaseline is stable, non-reactive under normal conditions, and resistant to weak acids and bases.

Vaseline is widely used as a base for ointments, creams, and lotions. Its hypoallergenic and non-comedogenic properties make it ideal for skin protection, wound care, and as a moisturizing agent in personal care products.
Food Processing
Utilized as a food-grade lubricant for machinery and as a release agent in food production. Certain grades are approved for incidental food contact due to their inert nature.
Electrical & Electronics
Applied to electrical terminals, battery posts, and connectors to prevent corrosion and moisture ingress. Its insulating properties make it suitable for protecting sensitive electronic components.
Automotive
Used for lubricating and protecting locks, hinges, battery terminals, and other metal parts from rust and corrosion. It ensures smooth operation and extends component life.
Metalworking & Engineering
Functions as an anti-corrosive coating for metal surfaces, tools, and precision instruments. Vaseline is also used as a lubricant for assembly and maintenance tasks.
Leather & Rubber Industry
Acts as a softener and conditioner for leather goods and rubber products, preventing drying, cracking, and extending material lifespan.
Textile Industry
Employed as a lubricant and softener in textile processing, aiding in the smooth operation of machinery and enhancing fabric feel.
Chemical Manufacturing
Serves as a carrier, diluent, or protective agent in the formulation and processing of various chemicals and specialty products.
Construction & Maintenance
Used for lubricating moving parts, protecting exposed metal fixtures, and as a temporary anti-corrosive barrier during storage or transport.
Household & DIY
Popular for general lubrication, rust prevention, and as a protective coating for tools, garden equipment, and household items.
Packaging Types
- Plastic Jars: Wide-mouth containers for easy access, ideal for industrial and household applications.
- Metal Tins: Durable, airtight tins suitable for storage and transport in harsh environments.
- Aerosol Cans: Sprayable Vaseline for convenient application in hard-to-reach areas and for uniform coating.
