Name an alternative to formaldehyde used in embalming fluids.

Glutaraldehyde is recognized as an alternative to formaldehyde in embalming fluids due to its effectiveness as a preservative and its ability to cross-link proteins, similar to formaldehyde. It is particularly appreciated because it is less toxic and irritating compared to formaldehyde, allowing for a safer working environment for embalmers. Glutaraldehyde has a broad-spectrum antimicrobial activity, which is essential in preventing decomposition during the embalming process.

In contrast, while alcohol can serve some role in embalming, it does not have the same level of preservation properties and is generally not used as a primary embalming agent. Benzaldehyde and acetic acid also lack the efficacy in protein cross-linking and preservation when compared to glutaraldehyde and formaldehyde. Therefore, glutaraldehyde stands out as a suitable alternative, offering embalmers a versatile option while addressing some of the health concerns associated with formaldehyde use.
