What is Soft Paraffin Ointment?
Soft paraffin ointment (also called white soft paraffin) is a bland, greasy emollient used to protect and moisturize damaged oral mucosa, particularly the lips, in conditions causing oral ulcers and erosions. 1
Primary Medical Uses
For Oral Ulcers and Mucosal Protection
- Apply white soft paraffin ointment to the lips every 2 hours during acute illness to create a protective barrier and maintain moisture 1, 2, 3
- The ointment acts as a physical barrier protecting damaged mucosa from further trauma, desiccation, and environmental irritants 1
- It is recommended as first-line supportive care in severe mucosal conditions like Stevens-Johnson syndrome/toxic epidermal necrolysis where oral involvement is prominent 1
For Urogenital Mucosal Protection
- Apply white soft paraffin ointment to urogenital skin and mucosae every 4 hours during acute illness to prevent adhesions and promote healing 1
- This application helps reduce pain and prevents formation of synechiae in affected areas 1
Mechanism and Formulation
Composition and Properties
- Soft paraffin is typically used as a 50:50 mixture with liquid paraffin (50% white soft paraffin with 50% liquid paraffin) for skin applications 1
- It functions as an occlusive emollient that reduces transcutaneous water loss and supports barrier function 1
- The greasy formulation encourages re-epithelialization of damaged tissue 1
Key Advantages
- Bland and non-irritating - contains no sensitizers or irritants that could worsen ulceration 1
- Safe for frequent application without risk of toxicity or adverse effects 1
- Can be used in combination with other topical treatments like corticosteroids and antimicrobials 1
Clinical Context for Oral Ulcers
Integration with Comprehensive Oral Care
- White soft paraffin should be used alongside daily warm saline mouthwashes or oral sponge cleaning 1, 2, 3
- Combine with anti-inflammatory rinses containing benzydamine hydrochloride every 2-4 hours, particularly before eating 1, 2, 3
- May be supplemented with topical corticosteroid mouthwashes (e.g., betamethasone sodium phosphate) four times daily for inflammatory conditions 1, 3
Important Clinical Considerations
- Daily oral review is necessary during acute illness when using this as part of ulcer management 1, 3
- The frequent application schedule (every 2 hours) is critical for maintaining protective coverage during the acute phase 1, 2
- This is a supportive measure that protects tissue but does not treat underlying causes of ulceration - specific therapies for infection or inflammation must be added as indicated 3, 4
