PHENYLACETALDEHYDE

Description

Phenylacetaldehyde is a versatile aromatic compound widely used in both skincare and fragrance formulations. This colorless to pale yellow liquid possesses a sweet, honey-like scent with floral undertones, reminiscent of hyacinth. In skincare applications, phenylacetaldehyde primarily functions as a fragrance ingredient, imparting a pleasant aroma to various products.

Beyond its olfactory properties, phenylacetaldehyde exhibits mild antimicrobial activity, potentially contributing to the preservation of cosmetic formulations. Its molecular structure allows for good skin penetration, which can enhance the overall sensory experience of skincare products. However, it's important to note that phenylacetaldehyde can be a skin sensitizer in some individuals, particularly at higher concentrations.

In terms of formulation, phenylacetaldehyde is typically used in low concentrations, usually below 1%, to minimize potential irritation while still providing effective fragrance. It blends well with other aromatic compounds and can help create complex, layered scent profiles in skincare products. When incorporating phenylacetaldehyde into formulations, careful consideration must be given to its potential allergenicity and regulatory limitations in different regions.
