For skin
- HumectantWater binding can help support a hydrated skin feel in a well-formulated product.
- Skin Conditioning - MiscellaneousA broad skin-conditioning role is recorded. A more specific benefit needs ingredient-level evidence.
A multifunctional formula ingredient commonly encountered in skincare and personal care.
Explore the recorded roles of PROPYLENE GLYCOL and what they can mean in a cosmetic formula.
The panels below interpret this ingredient’s recorded functions. They describe possible contributions, not proven clinical results. Any individually reviewed study is shown separately.
No hair-specific function has been mapped from this source record. Hair or scalp benefits have not yet been reviewed here.
Examples associated with the recorded function classes; these are not verified product listings or instructions to apply the raw ingredient.
Ingredient form, concentration, pH, delivery system and contact time can change the result. A skin finding does not establish a hair benefit; a conditioning or fibre result does not establish hair growth.

European Commission · source text, with formatting normalised · CC BY 4.0CAS and EC identifiers are source references. A botanical extract, polymer or mixture may have more than one identifier; a name does not establish purity, supplier grade or sourcing.
Matched through one source CAS and a confirmed ingredient name or source alias. These facts describe the matched PubChem record; they do not describe particle form, supplier grade or finished-product performance.
Helps a formula attract and retain water. The overall moisturising effect depends on the complete product.
Contributes scent to a product. Fragrance character depends on the ingredient blend.
Dissolves or carries other formula ingredients. A solvent can help bring different components into a usable product.
Helps adjust how thick or fluid a formula is, influencing its flow and application.
Supports a moisturised skin feel through water-binding properties.
A broad source category for ingredients that help keep skin in good condition through roles not described by a narrower conditioning category.
Functions describe possible roles in a formulation. They do not establish the performance of every product containing this ingredient.
Propylene glycol is distinct from propanediol and from ingredients with longer compound names.
Its function depends on the formulation. Research the complete product and use conditions rather than the name alone.
Applicable Cosmetics Rules and standards need to be checked for the ingredient, product type and use. Ingredient-specific restrictions have not yet been mapped here.
CosIng records do not authorise use. Check the current Cosmetics Regulation and annexes for restrictions and conditions.
FDA guidance has a US scope. Product classification, colour additives and other ingredient conditions require separate checks.
No personalised suitability or allergy assessment is provided. A source function is separate from human efficacy and finished-product testing.
