The pH buffer solution market size was valued at US$ 1.54 billion in 2023 and is expected to reach US$ 2.26 billion by 2031; it is estimated to register a CAGR of 5.0% from 2023 to 2031.

The demand for personal care products is increasing remarkably with the changing lifestyles of people, rising disposable income, increasing number of working professionals, and rising focus on personal grooming. Moreover, the rising impact of social media and celebrities on people's lifestyles drives the demand for various skincare, haircare, and fragrance products. Individuals follow skincare and haircare regimes and use specialized products that help them achieve youthful skin and luscious, beautiful hair.

The pH buffer solution prevents the products from becoming too acidic or alkaline, which might cause skin irritations. For example, soap has a naturally high PH, typically buffered to a pH of ~5.5, which is the skin's natural PH. Similarly, citric acid and sodium citrate are commonly used as buffers to maintain slightly acidic PH, which works against the natural alkalinity of the detergents in shampoo that might result in scalp burn. pH buffer solution in baby lotions prevents the growth of bacteria and nappy rush. It is an important precursor for manufacturing personal care and cosmetic products. Thus, the increasing utilization of pH buffer solutions in the personal care industry is expected to bring new trends in the pH buffer solution market growth during the forecast period.



On the basis of application, the pH buffer solution market is segmented into laboratory, personal care and cosmetic, textile, food and beverages, pharmaceuticals, electroplating, paper manufacturing, and others. In 2023, the laboratory segment accounted for the largest market share. In labs, buffers have extensive applications in performing enzymatic reactions or cellular studies to maintain their pH and activity during the reaction. These buffers also have applications in calibrating pH meters and chemical analysis. Standard buffer solutions with known pH values help calibrate instruments accurately, ensuring precise readings in subsequent analyses. One of the primary uses of pH buffers in the laboratory is in titrations, where the pH of a solution is monitored and adjusted to determine the concentration of an unknown substance. Buffers provide a stable pH, ensuring precise measurements and preventing errors caused by pH fluctuations. Maintaining the correct pH in biological experiments is critical, as enzymes and proteins often function optimally within a narrow pH range. Buffers help sustain the desired pH for reactions involving enzymes, DNA, or cell cultures, ensuring consistency in experimental outcomes. Also, pH buffers are used in chromatography and electrophoresis, where the pH of the mobile phase or running buffer can significantly impact the separation and migration of molecules.

North America is estimated to register the fastest CAGR in the global pH buffer solution market from 2023 to 2031.
