N‑Acetylneuraminic Acid (Sialic Acid) Raw Material Introduction

N‑Acetylneuraminic acid (Neu5Ac, commonly known as bird’s nest sialic acid) is a nine‑carbon amino monosaccharide and an active ingredient applicable for both food and cosmetic use, manufactured via microbial fermentation. In food applications, N‑acetylneuraminic acid participates in nervous system development, maintains mucosal immunity and exhibits antioxidant activity. In cosmetics, it repairs the skin barrier, scavenges free radicals to deliver anti‑aging effects and modulates melanin synthesis. This article reviews the physicochemical properties and mechanism of action of the ingredient, as well as regulatory requirements and applicable product categories for its use in food and cosmetics in China.

PCA Zinc Oil Control Without Drying — In-Depth Principles | Shampoo Anti-Dandruff Application Guide

Most oil-control cleansers and skincare ingredients currently on the market share a significant shortcoming: those that merely absorb surface oil tend to leave the skin and scalp feeling tight and dry, while aggressive degreasing agents can compromise the stratum corneum barrier. Prolonged use often leads to water-oil imbalance, a cycle of "the more you control, the more oil you produce," scalp dryness, and itchiness. Zinc PCA (pyrrolidone carboxylic acid zinc), a novel organic zinc salt, addresses these pain points of traditional oil-control ingredients through its triple-action profile — "root-cause oil control + long-lasting hydration + mild antimicrobial action" — and has become a sought-after core ingredient in both facial oil-control and scalp care domains. Unlike irritating inorganic zinc salts such as zinc sulfate, Zinc PCA is a chelated compound of PCA (a Natural Moisturizing Factor) and zinc ions, simultaneously offering oil-regulating and barrier-repairing capabilities. This article focuses on dissecting the core principle of how PCA Zinc controls oil without drying, while also sharing a targeted PCA Zinc shampoo anti-dandruff application formulation guide, suitable for new product development, formulation optimization, and raw material procurement reference.

HEPES Raw Material Guide: Mechanism of Action, Formulation Applications, and Cosmetic Compliance Essentials

4-Hydroxyethylpiperazine Ethane Sulfonic Acid, INCI: Hydroxyethylpiperazine Ethane Sulfonic Acid, abbreviated as HEPES, CAS: 7365-45-9, is a zwitterionic biological buffer ingredient originally developed for cell biology experiments and now widely used in skincare and cosmetic systems. Its core function is stabilizing formulation pH with a buffering range of 6.8–8.2. It is heat-stable and oxidation-resistant, helping protect actives such as peptides, vitamins, and acids. In certain formulation systems, it also provides auxiliary keratolytic effects and synergistic enhancement of functional ingredients. It is commonly used in serums, masks, exfoliating treatments, and eye care products. This article covers the ingredient's physicochemical properties, mechanism of action, suitable product applications, recommended usage levels, formulation challenges, and domestic cosmetic compliance requirements to support R&D and procurement teams in making informed selections.
