Pentadecalactone
What Pentadecalactone is & what it does
Pentadecalactone is a large-ring lactone (a cyclic ester) with a soft, musky character, widely used as a fragrance ingredient. In cosmetics and sunscreens it most often contributes to the scent of a product rather than to skin care function. Its long-lasting, musky note makes it a common base for fragrance blends.
What does Pentadecalactone do in skincare?
Pentadecalactone is primarily a fragrance ingredient with a soft, musky scent. In skincare and sunscreen products it mainly contributes to the overall fragrance rather than to a skin-care function. Its long-lasting musky note makes it a common base for scent blends.
Is Pentadecalactone safe?
Pentadecalactone is a widely used musk-type fragrance ingredient and is generally regarded as acceptable for use in cosmetics within established fragrance guidelines. Fragrance components can occasionally cause sensitivity in people prone to it. If you have fragrance-sensitive skin, choosing fragrance-free options or patch testing is a good idea.
Is Pentadecalactone natural or synthetic?
Pentadecalactone occurs naturally in trace amounts (for example in angelica root), but the material used in cosmetics is almost always produced synthetically for consistency and supply. The synthetic version matches the natural musk compound.
