P-anisic acid
Harm score: 2 (Derivatives of natural substances)
P-anisic acid, also known as "Nonionic surfactants", is a substance that retains its chemical stability despite a wide range of pH values. This fact makes it suitable for use in the cosmetic and pharmaceutical industries. It has antimicrobial properties and is able to dissolve a number of organic compounds. The structure of p-anisic acid consists of a phenyl functional group linked to a carboxyl group via a methylene bridge. This plant extract, which is most commonly released from anise, is resistant to the effects of light, heat and air, making it an ideal preservative.
The cosmetics industry often uses this substance in skin care products where it serves as a preservative. It is added to creams, face masks, moisturizing serums and other products where it helps prevent the growth of bacteria and fungi. P-anisic acid is also often found in perfumes, where it adds a sweet and spicy scent. In the pharmaceutical industry, p-anisic acid is used as an additive to improve the taste of drugs, as its sweet and aromatic flavor profile can help mask the unpleasant tastes of active pharmaceutical ingredients. The substance is also a component of some food products, primarily as a natural flavouring additive.
