Product Description

Marcol 52 is a highly purified blend of liquid saturated hydrocarbons. This clear, colorless, and oily liquid is virtually odorless and tasteless. It is obtained from petroleum through several refining stages, including an ultimate purification by catalytic hydrogenation.

Manufactured to surpass Pharmacopoeia purity standards, Marcol 52’s exceptional chemical stability provides improved color and oxidation resistance compared to most mineral and vegetable oils, especially when stored and used under controlled conditions

     •  CAS number: 8042-47-5

     •  EINECS number: 232-455-8

     •  INCI name (Europe): Paraffinum Liquidum

     •  CTFA Dictionary name (USA): Mineral Oil

Applications

Marcol 52 is suitable for various applications in food-contact, cosmetic, and pharmaceutical products, provided it complies with the relevant laws and regulations in each country.

To reduce ingestion and aspiration risks, Marcol 52 should not be used in nasal, oral, or lip care products, nor as a food additive beyond its role in food-contact materials.

Users are responsible for verifying regulatory compliance.

Cosmetics
Marcol 52 is widely used in cosmetic formulations, including:

     •  Cleansers
     •  Hair care products
     •  Neutral and protective diluents for other cosmetic ingredients, such as essential oils
     •  Additional applications like makeup and makeup removers
For formulators, Marcol 52 offers numerous advantages:

     •  Excellent skin compatibility with low irritation and comedogenic potential
     •  Good balance of bacterial resistance and biodegradability, resulting in minimal environmental impact
Pharmaceuticals and Veterinary Products
With its high purity, Marcol 52 is safe for pharmaceutical and veterinary applications. Its key features include the absence of toxic polycyclic aromatics and heavy metals, complete germ destruction through high-temperature processing, and strict packaging and handling standards.

Primary uses include:

     •  As an adjuvant in animal vaccines (for cattle, chickens, and pigs), where its low viscosity supports optimal effectiveness
     •  In the production of gelatin capsules
