What is Pure Allantoin CAS 97-59-6?

Pure Allantoin CAS 97-59-6 is a white crystalline powder with the molecular formula C4H6N4O3 and molecular weight 158.12 g/mol. It is used as a skin-soothing and mild keratolytic ingredient in cosmetics and topical formulations.

How does Allantoin function in skin care products?

Allantoin helps soften the outer skin layer and is widely used as a soothing agent in leave-on and rinse-off products. It is compatible with many cosmetic systems and is often included in sensitive-skin, baby-care and after-sun formulations.

What are the solubility and pH properties of Allantoin?

Allantoin is slightly soluble in cold water and more soluble in hot water or dilute alkali. It is amphoteric and generally stable over a broad pH range, making it easy to incorporate into different cosmetic bases.

What are common applications for Allantoin?

It is used in creams, lotions, serums, cleansers, shaving products, after-sun care, baby products and some oral care formulations. Typical cosmetic use levels are low, often around 0.2-0.5% in leave-on skin care.

What quality specifications apply to high-purity Allantoin?

USP/EP and cosmetic grades are commonly controlled for assay, melting point, loss on drying, residue on ignition, acidity or alkalinity, heavy metals and solution appearance. Store it sealed in a cool, dry place.
