Yellow Petrolatum (CAS 8009-03-8) is a purified semisolid mixture of hydrocarbons obtained from petroleum. It is a yellow to amber, translucent, unctuous mass with the same basic composition as white petrolatum but without the final decolorization step. Yellow petrolatum is used as an ointment base, emollient, and moisture barrier in pharmaceutical and veterinary topical formulations.
TCS Industries Limited, a Hong Kong-based trading and sourcing company, supplies Yellow Petrolatum in pharmaceutical (USP) and industrial grades for global procurement programs.
> Applications
Ointment base for veterinary and industrial topicals
Yellow petrolatum is the traditional ointment base used in veterinary medicine (hoof dressings, udder balms, wound protectants) and industrial applications (rust-preventive coatings, leather treatment) where the yellow colour is acceptable or desired. It provides the same occlusive, moisture-barrier function as white petrolatum at lower cost. Lesiak-Cyganowska et al. (Pol J Vet Sci, 2005, 8:339–342) studied petrolatum-based wound dressings in veterinary healing applications.
Compounding base and protectant
Yellow petrolatum USP is used in pharmacy compounding for ointments and pastes where colour is not a concern. It serves as the vehicle in Yellow Ointment USP (5% yellow wax + 95% yellow petrolatum). As a skin protectant, it reduces transepidermal water loss with the same efficacy as white petrolatum.
> Sourcing & Supply
TCS Industries Limited supports development, qualification and commercial purchasing discussions for Yellow Petrolatum –- Traditional Ointment Base & Moisture Barrier with buyers in South America, Europe, the United Kingdom, Australia, New Zealand, Mexico and Canada.
- Evaluation and commercial quantities: 1 kg samples for formulation trials; 25 kg, 50 kg, or 170 kg drums for production. Pharmaceutical (USP) grade in multiple consistency ranges available.
- Pallet quantities and production campaigns: repeat supply is coordinated against packaging, lead time, annual demand and destination-market import requirements.
> Quality & Documentation
Key specification parameters include colour (yellow to light amber), melting point (38–60 °C, grade-dependent), consistency (cone penetration), UV absorption (290–350 nm, indicating aromatic hydrocarbon content), sulfur compounds, residue on ignition, acidity/alkalinity, and microbial limits. Yellow petrolatum has slightly higher aromatic hydrocarbon content than white grade due to fewer refining steps. Meets USP (Petrolatum) and BP (Yellow Soft Paraffin). COA and MSDS are standard.
> Packaging
Yellow petrolatum is a semisolid that softens at body temperature. Standard packaging includes 25 kg or 170 kg steel drums with lacquer lining. Store at room temperature (15–30 °C). Protect from contamination and strong odors. Shelf life is typically 36–60 months. Labels and documents are checked before dispatch.
> Pricing & MOQ
Pricing is quoted by specification, packaging and destination. Common commercial discussions use 25 kg bag/drum formats, pallet quantities and production-campaign planning; smaller samples may be reviewed for qualified formulation teams.
> Regulatory & Compounding Context
Yellow petrolatum is monographed in USP (Petrolatum), BP (Yellow Soft Paraffin / Paraffinum Molle Flavum), and Ph.Eur. Listed in the FDA IID for topical dosage forms. FDA-approved OTC skin protectant (21 CFR 347.10, 30–100%). Not commonly used in modern cosmetic products due to colour. No special import permits.

> FAQ
What is the difference between Yellow and White Petrolatum?
Both share CAS 8009-03-8 and the same hydrocarbon base. White petrolatum undergoes additional decolorization (activated carbon or hydrogenation) to remove colour bodies and reduce aromatic hydrocarbons. Yellow petrolatum retains its natural colour and has slightly higher aromatic content. White grade is preferred for pharmaceutical and cosmetic use; yellow grade is used in veterinary, compounding, and industrial applications.
What documents are available for Yellow Petrolatum –- Traditional Ointment Base & Moisture Barrier orders?
COA and MSDS are standard for commercial discussions. COO, packing list, invoice and other import-support documents can be arranged according to order scope.
Can TCS Industries Limited support Yellow Petrolatum –- Traditional Ointment Base & Moisture Barrier supply to South America?
Yes. We support B2B buyers in Argentina, Colombia, Chile, Peru, Ecuador, Uruguay, Bolivia, Brazil, Paraguay, Venezuela, Guyana and Suriname, subject to route and document review.
Do you support Europe, the United Kingdom, Australia, New Zealand, Mexico and Canada?
Yes. These destinations can be reviewed for project supply, import documents, packaging and logistics planning before quotation.
Is Yellow Petrolatum USP grade available?
Yes. USP monographs both “White Petrolatum” and “Petrolatum” (yellow grade) as separate entries with identical specifications except colour. Yellow Petrolatum USP meets all purity requirements for pharmaceutical use. It is used in compounding pharmacies and veterinary formulations.
Can Yellow Petrolatum be used in cosmetics?
Technically yes, but modern cosmetic products use white petrolatum for aesthetic reasons. Yellow petrolatum is not prohibited in cosmetics. It is used in industrial and specialty products where the amber colour is acceptable or desired (leather conditioners, protective balms).
Can you arrange samples before commercial purchasing?
Samples or evaluation quantities may be reviewed for qualified buyers after target specification, application and destination-market requirements are clarified.
How is Yellow Petrolatum –- Traditional Ointment Base & Moisture Barrier packaged for export?
Packaging is confirmed by quantity and material properties. Typical options include foil bags, HDPE containers, fibre drums, 25 kg bags or palletized export packaging.
Can buyer-defined specifications be reviewed?
Yes. Send the specification, methods, impurity limits and required documents. TCS can review feasibility before confirming quotation and lead time.
What payment terms are normally used?
Standard payment is 100% T/T before dispatch unless a different arrangement has been approved for an established commercial account.
What lead time should buyers expect?
Lead time depends on stock, batch size, document scope and destination. Available stock can move faster; made-to-order or pallet programs require longer planning.
What consistency grades are available?
Yellow petrolatum is available in soft (melting point 38–47 °C), standard (47–54 °C), and firm (54–60 °C) grades. Select based on intended ointment consistency and climate. Tropical markets require firmer grades to prevent excessive softening during storage and transport. Specify melting point range at inquiry.
