Product Description
PCA Na Powder, full name Sodium Pyrrolidone Carboxylic Acid, is the skin's own Natural Moisturizing Factor in high-purity crystalline powder form, delivering lightweight, non-tacky and long-lasting hydration to finished formulas, it is not classified as an anti-aging or whitening active, yet most comfortable-feel moisturizing and soothing care systems simply cannot achieve their optimal water-binding performance without it; it works by mimicking the endogenous NMF mechanism, actively capturing ambient moisture and forming a slow-release reservoir inside the stratum corneum, unlike conventional humectants like glycerin or propylene glycol which often leave a sticky film, PCA Na offers a remarkably higher water-holding capacity with a nearly weightless, non-shiny finish, never clogging pores or causing greasy afterfeel, its thermal stability is excellent and non-volatile, standing up to high-temperature processing without degradation, meanwhile it is virtually odorless, introducing no interference to the fragrance profile, while continuously relieving tightness, flakiness and discomfort caused by dryness; typical cosmetic use level ranges from 0.2% to 5.0%, underdosing may lead to weak moisturizing endurance while overdosing could bring a slightly tacky sensation, this product appears as an off-white crystalline powder with almost no smell and outstanding compatibility across anionic, nonionic and amphoteric ingredients, at recommended doses it is skin-respecting, non-sensitizing and perfectly safe for reactive and sensitive skin types, only raw bulk powder may mechanically irritate eyes and respiratory tract, so basic dust protection is advised during factory handling, it stands as a trusted, universally reliable foundational moisturizing ingredient in the personal care and cosmetic industry.
