Which group includes common humectants used in embalming?

The correct answer focuses on the specific substances that act as humectants in embalming. Glycerin, sorbitol, and propylene glycol are all known for their ability to retain moisture, making them effective humectants. In the context of embalming, humectants are important because they help to prevent dehydration of tissues, contributing to better preservation and cosmetic effects.

Glycerin, for instance, is a well-known humectant that draws water to tissues and helps maintain moisture levels. Sorbitol serves a similar function, being effective in retaining moisture while also having a sweet taste, which can be beneficial in some formulations. Propylene glycol is another versatile humectant, often used in various applications, including embalming, to help with moisture retention.

The other groups listed do not contain the specific moisture-retaining characteristics defined by humectants, making them unsuitable for this context. While water and salts can be important in embalming solutions, they do not qualify as humectants themselves. Alcohols and phenols are more often associated with disinfecting and preserving properties rather than moisture retention. Similarly, acids and bases do not fit into the humectant category, as they pertain more to pH adjustment rather than the
