What it is
Triacontanyl PVP is an alkylated polyvinylpyrrolidone in which a long triacontanyl (C30) chain is attached to the PVP backbone, giving it both oil-friendly and polymeric character. In formulations it helps form films, structure the oil phase, and stabilize emulsions and pigments, which can improve the wear and uniformity of sun and color products. It is typically used at modest levels as a texturizing and stabilizing aid.
Safety & warnings
Triacontanyl PVP is a large polymer that is generally well tolerated on skin and low in irritation potential at cosmetic levels. It is not a recognized fragrance allergen. As a wax-like, long-chain material it is used at low levels and is not typically flagged as a notable comedogenic ingredient.
Origin & sourcing
A synthetic polymer produced by modifying polyvinylpyrrolidone with a long-chain alkyl group.
Questions everyone asks
What does triacontanyl PVP do in sunscreen?
It acts as a film former and stabilizer, helping structure the oil phase and improve the evenness and wear of the product.
Is triacontanyl PVP a natural ingredient?
No, it is a synthetic polymer made by attaching a long-chain alkyl group to polyvinylpyrrolidone.
