We appreciate at Chromak Research the significance of water testing to the stability, quality, and safety of cosmetic and personal care product formulations. Water is not merely a base ingredient—typically, it comprises 60% to 90% of the formula in cosmetics such as creams, lotions, shampoos, and cleansers. Poor or contaminated water can destroy your entire formula, affecting its appearance, functionality, and microbiological safety.

That is why our lab offers comprehensive water testing services to ensure that the water used in your cosmetic production meets international quality and safety requirements. As an experienced contract testing laboratory, Chromak Research helps cosmetic manufacturers, formulators, and businesses maintain product integrity from product creation to market introduction.

1,4-Dioxane Contaminant Testing

Why is Water Testing Important in Cosmetics?

Water is a potential source of microbial contamination if it is not controlled and treated. It is also able to carry unwanted chemical impurities like heavy metals, residual disinfectants, organic matter, or dissolved solids, which are able to change the pH, texture, or shelf life of the finished product. Daily water quality analysis ensures:

Microbiological purity of the product

Chemical safety and freedom from toxic residues

pH balance within desired range

Compliance with FDA, and ISO standards

Protection from product contamination or harm to human health

We at Chromak Research use validated procedures and state-of-the-art equipment to give you accurate and timely analysis on each batch of water used in your manufacturing.

Key Parameters in Water Testing

We conduct a broad set of tests to assess both microbiological and chemical characteristics of water utilized in cosmetic and personal care production. Our water testing services comprise:

Microbiological Testing

  • Total viable count (TVC)
  • Yeast and mold count
  • Identification of certain pathogens (e.g., Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli)
  • Endotoxin content

Chemical Analysis

  • pH and conductivity
  • Total Organic Carbon (TOC)
  • Residual chlorine or disinfectants
  • Heavy metals (lead, arsenic, cadmium, mercury)
  • Nitrates, sulfates, and hardness
  • Turbidity and dissolved solids

We also provide water classification based on international standards (e.g., USP Purified Water, EP Water for Preparation, ISO 3696 Grade 2 or 3 Water).

Applications of Water Testing in Cosmetics

Our water testing services are vital for manufacturers of:

  • Skincare products (creams, lotions, moisturizers)

  • Hair care products (conditioners, shampoos, serums)

  • Personal hygiene products (face washes, hand sanitizers, body washes)

  • Color cosmetics (primers, foundations, sprays)

  • Oral care (toothpaste, mouthwashes)

Water applied in washing equipment, rinsing vessels, and in formulation is also analyzed to ascertain hygienic processing.
