What it is

Propanediol is the ingredient name recorded as PROPANEDIOL in INCI. The entry identifies it as an organic compound and lists 1,3-dihydroxypropane as its chemical name; that designation gives the substance a more precise identity than the INCI name alone.

CAS number 504-63-2 and EC number 207-997-3 accompany the available identification. Together, the INCI name, chemical name and identifiers make it possible to recognise the same ingredient when it appears in a composition list.

What it does in a formula

PROPANEDIOL is listed with the functions SOLVENT and VISCOSITY CONTROLLING. The solvent classification refers to the role recorded for the substance within a formula, while viscosity controlling describes another technical function listed for the ingredient.

Those two roles help explain why propanediol may be included in a cosmetic composition. The entry does not state proportion, interaction with other components or the result of use in a particular product.

Conditions and care

No cosmetic restriction, maximum concentration, condition of use or other regulation is filled in for PROPANEDIOL in this entry. There is also no accompanying text from which a numerical limit or a particular condition could be drawn.

That absence applies only to the fields available here. It should not be read as a safety assessment or as confirmation that no limits or care may exist in information not included in this entry.
