Pyrrolidinyl diaminopyrimidine oxide

Pyrrolidinyl diaminopyrimidine oxide (CAS 55921-65-8 ) is a synthetic heterocyclic compound used in personal care formulations as a scalp and hair treatment active. It functions primarily as an antioxidant agent, protecting follicular tissue from oxidative stress in topically applied products.

In hair care, it is incorporated into leave-on scalp serums, anti-hair loss treatments, and trichological formulations where oxidative damage to the follicle environment is a primary concern. Cosmetic formulators use it alongside other actives in premium scalp care lines.

These formulations often target thinning hair and age-related follicle decline. In pharmaceutical-adjacent topical preparations, it is evaluated for its capacity to support scalp health through antioxidant stabilization mechanisms during the application process.

Its compatibility with aqueous and emulsion-based systems makes it a practical choice for rinse-off and leave-on formats alike. This versatility allows manufacturers to integrate the compound into a wide variety of existing product bases without stability issues.

Pyrrolidinyl diaminopyrimidine oxide is typically supplied as a solid powder or in solution form suitable for cosmetic manufacturing. Material is generally available to cosmetic-grade specifications for industrial use.

Documentation packages including MSDS, COA, and purity data are provided to support regulatory submissions. Quantities range from research-scale to commercial bulk, depending on the specific requirements of the supplier and the end user.
