Heneicosane

Heneicosane is a straight-chain alkane hydrocarbon (C21H44), naturally occurring in some plant waxes and insect pheromones. It is not used as a food ingredient and primarily appears in materials context. As a hydrocarbon, it is combustible and may be used in fragrance formulations or wax products. No evidence supports its toxicity at typical exposure levels; however, inhalation of combustion products may pose respiratory risks.
