ALLANTOIN: what it is

Allantoin is the English name recorded for ALLANTOIN. The entry lists the chemical designation Urea, (2,5-dioxo-4-imidazolidinyl)-, which provides an additional technical reference for identifying the ingredient beyond its INCI name.

CAS number 97-59-6 and EC number 202-592-8 accompany that designation. These identifiers help recognise the substance in the record without stating concentration, formula combination or the effect of a particular product.

ALLANTOIN: what it does in cosmetics

ALLANTOIN is classified as SKIN CONDITIONING, SKIN PROTECTING and SOOTHING. The entry brings together skin conditioning and protecting categories, along with the soothing classification, which is retained as a recorded function of the ingredient.

Those terms describe roles assigned to allantoin in a cosmetic formula. They do not establish what effect will occur for a person, at what intensity or how the ingredient was combined with the other components of a package.

ALLANTOIN: conditions and care

This entry does not provide a cosmetic restriction, maximum concentration, condition of use or other regulation for ALLANTOIN. There is also no accompanying text from which a limit of use could be established using the information available.

The absence of those fields is not a safety assessment. It only shows that the displayed record does not provide the elements needed to define a numerical limit, individual care or use instruction.
