NITROCELLULOSE
Is NITROCELLULOSE safe for seborrheic dermatitis?
Nitrocellulose is generally lower concern from a seborrheic-dermatitis perspective, but it is rarely relevant to facial or scalp care. It forms a hard, fast-drying film and is used mainly in nail products, not to treat skin.
A cosmetic safety assessment supports the uses and concentrations it reviewed, which were dominated by nail products. No direct human seb derm or ingredient-specific Malassezia evidence was found. If it appears in a specialist film-forming product near affected skin, solvents, resins and fragrance are likely to matter more for irritation than Nitrocellulose alone.

What is NITROCELLULOSE used for in skincare?
Nitrocellulose is cellulose modified with nitrate groups so it can dissolve in selected solvent systems and form a durable film as the solvent evaporates. It provides adhesion, gloss and wear, especially in nail polish. It is commonly combined with solvents, plasticisers, resins and pigments rather than used as a moisturising skincare ingredient.
