Product Features & Efficacy

1. High-Efficiency Hydration & Moisture Locking

As a vital component of the skin's Natural Moisturizing Factors (NMF), PCA-Na possesses powerful hygroscopic and moisture-locking capabilities. It attracts moisture from the air and minimizes transepidermal water loss, offering significantly superior hydration compared to traditional humectants like glycerin and propylene glycol.

2. Gentle, Skin-Friendly & Barrier Repair

Highly compatible with human skin, it is mild and non-irritating. It enhances stratum corneum hydration, alleviates dryness, roughness, and flaking, and helps repair damaged skin barriers, making it ideal for formulations targeting sensitive and dry skin.

3. Soft Skin Feel & Texture Enhancement

It imparts a fresh, non-sticky sensation, leaving the skin soft, smooth, and free from tightness. It is widely used to elevate the sensory experience (skin feel) of skincare and personal care products.

4. Antioxidant & Soothing Properties

It assists in antioxidant protection and alleviates discomfort caused by external stressors, thereby improving the overall health of the skin.

What are the key technical specifications of PCA-Na?

PCA-Na typically comes as a clear, transparent liquid with an assay of 50%–55%, a pH range of 6.5 to 7.5, and heavy metal content restricted to ≤ 10ppm.

How does PCA-Na perform compared to traditional moisturizers like glycerin?

PCA-Na offers superior hygroscopic (moisture-attracting) efficiency compared to standard humectants like glycerin or propylene glycol. Additionally, it provides a much fresher, softer, and non-tacky skin feel.

Which product formulations can benefit from PCA-Na?

It is highly versatile and widely used across facial skincare (serums, creams, masks), hair care (shampoos, conditioners), personal body cleansers, and daily care products like body lotions and aftershaves.
