Why it may be in a product
It can influence water retention, spread and feel as one part of a wider moisturising system.
What the name tells you
It identifies a familiar humectant, skin-conditioning and solvent ingredient in the formula.
What the label cannot tell you
It cannot establish origin, concentration, tack, water activity, hydration result, preservation or suitability. ‘Vegetable glycerin’ is equivalent only when source is separately documented.
Evidence status
Function terminology established; limited canine finished-formula evidence does not isolate glycerin's effect.

The glossary uses official European sources to check ingredient terminology and to keep medical, biocidal and finished-product claims outside the glossary. Cosmetic references concern human products; their use here is limited to names and reported formulation functions.

- What to look for in a dog shampoo before you buyWhat an ingredient name cannot tell you · Examples of names from four different functional groups, showing what a lookup returns. This is not a ranking, a shortlist of concerns or a list of names to avoid.
- How often should you bathe a dog?A wash and a leave-on product are used differently · Examples of cleansing-function terminology and of terminology associated with leave-on formats. The names establish neither how often a product is used, nor in what format, nor whether it suits an individual dog — the product's own directions state its intended use, and a veterinarian is who adjusts anything for a particular animal.
- Everyday care for sensitive and atopic canine skinLeave-on care and contact time · Examples of humectant, emollient or film-forming functions. Their presence does not establish duration, efficacy or tolerance.
