Is the texture greasy, and will it stain clothing?

Yes, this is a genuinely rich, occlusive ointment rather than a lotion. The base is built on petrolatum and paraffin, which makes it dense, slow to spread and leaves a visible protective film on the skin. That film is intentional — it holds the camphor on the applied area instead of letting it evaporate or absorb away quickly — but it does mean the treated spot stays slightly greasy for a while.

Practical consequences worth knowing:

• Clothing: like any petrolatum-based product, it can leave greasy marks on fabric. Give the ointment several minutes to settle before dressing, or apply it in the evening when you can wear something you do not mind marking. Greasy spots on fabric usually come out with a pre-treatment of dish soap or a degreasing stain remover before a normal wash.
• Removal from skin: plain water will not take it off. Use warm water with soap, and repeat if needed; an oil-based cleanser also breaks down the film effectively.
• Consistency and storage: petrolatum-paraffin bases firm up in the cold and soften in warmth, so the texture may vary slightly with room temperature. Keep the tube closed and away from heat to preserve the camphor aroma.

If you prefer products that vanish into the skin without trace, this format will feel heavy — the density is a deliberate trade-off for a longer-lasting camphor effect.
