Dihydroxypropyl Arginine HCL is a conjugate of Glycerin and Arginine that combines both ancestors' moisturizing (NMF) and high adsorption power. It creates hydrogen and ionic bonds with skin and hair surface molecules, attaching like a magnet even in rinse-off applications and providing a long-lasting humectant effect.

Thanks to the polar guanidino group in arginine (ionic bond) and double hydroxyl groups dihydroxypropyl tail (hydrogen bonds), Dihydroxypropyl Arginine HCL adsorbs to epidermis (stratum corneum) and hair keratin. In the case of hair care, it also penetrates the inner layers of hair because of its low molecular weight and keeps moisture.

Besides its NMF-like moisturizing effect, Dihydroxypropyl Arginine HCL suppresses abnormal cornification and multilayer desquamation of the stratum corneum and preserves the skin's barrier function. It exhibits noticeable anti-wrinkle action while lessening rough skin sensation and improving skin texture. In addition, it tightens pores and reduces inflammation.

Incorporated in hair care applications, Dihydroxypropyl Arginine HCL adsorbs and delivers moisture to damaged hair, providing long-lasting moisturization even after washing off. It improves hair combability, acts as an antistatic agent, and controls hair spreading, which is usually
observed under increased humidity conditions.

Dihydroxypropyl Arginine HCL is a safe ingredient for skin, hair, and scalp care products. It is non-irritant to skin and eyes, non-sensitizer, and non-mutagenic.
