Onnocare Production Hygiene Program

Onnovo’s Production Hygiene Program (OPHP) Ensuring Superior Microbial Control & Long-Term Product Integrity

In industries where water-based formulations and high-volume manufacturing are critical, microbial contamination can pose serious risks—compromising product quality, damaging reputation, and leading to costly recalls.

Onnovo’s Production Hygiene Management Program (PHP) is a comprehensive, science-driven solution designed to protect your products by addressing microbial risks at every stage of production.

From raw material selection to final product storage, PHP ensures a clean, contamination-free production environment, reducing microbial growth and extending the lifespan of your materials.

The Hidden Threat: Why Microbial Contamination Matters

Many industrial formulations—such as paints, coatings, adhesives, emulsions, construction chemicals, and personal care products—are highly susceptible to microbial contamination.

Water-based systems create an ideal environment for bacteria and fungi.

  • Microorganisms can enter through water, air, raw materials, processing equipment, and even packaging.
  • Once inside, they multiply exponentially, leading to contamination and potential product failure.

Common Consequences of Microbial Contamination:

  • Loss of viscosity – affecting texture and performance.
  • Color changes – leading to off-spec products.
  • Unpleasant odors – signaling spoilage.
  • Surface growth – visible fungal or bacterial colonies.
  • Product instability & separation – impacting quality and customer satisfaction.
  • Regulatory non-compliance – risking fines, recalls, or legal action.

Here’s the expanded section on Common Consequences of Microbial Contamination, with detailed explanations for each point:

Common Consequences of Microbial Contamination

Microbial contamination can have severe consequences on product quality, operational efficiency, and regulatory compliance. Below are some of the most critical issues that arise due to microbial growth in production environments:

Loss of Viscosity

Viscosity is a key property in many industrial formulations, including paints, coatings, adhesives, emulsions, and personal care products. When microbial contamination occurs, bacteria and fungi can produce enzymes that break down the polymer structures or thickeners, leading to a loss of viscosity.

In water-based systems, certain bacteria consume organic compounds, reducing the molecular weight of viscosity-controlling agents. This results in a thinner, more watery product that no longer meets performance specifications. Low-viscosity products may fail to adhere to surfaces properly, separate during storage, or require costly reformulation and reprocessing.

Color Changes

Microbial contamination can cause undesirable color shifts in finished products. Some bacterial and fungal species produce pigments as part of their metabolic process, leading to visible discoloration.

For example:

  • Bacteria such as Serratia marcescens produce a red pigment that can alter the appearance of coatings, cosmetics, or industrial slurries.
  • Mold and fungi can create dark spots or streaks on the surface of water-based materials.
  • Some microbial byproducts react with metal ions or chemical ingredients, resulting in yellowing or browning of the final product.

In industries where color consistency is crucial (e.g., paints, cosmetics, and food packaging materials), even minor shifts can render an entire batch unsellable.

Unpleasant Odors

A foul or unusual smell is often one of the first warning signs of microbial contamination. Bacteria and fungi produce volatile organic compounds (VOCs), which release unpleasant odors as they break down organic material in the formulation.

These odors can range from:

  • Rotten, sulfur-like smells – caused by sulfate-reducing bacteria.
  • Earthy, musty odors – produced by mold or actinomycetes.
  • Sour or rancid scents – indicating the degradation of emulsifiers or oils.

Odor contamination is especially problematic in coatings, adhesives, and personal care products, where consumer perception is critical. Even if the product remains functional, an off-putting smell can lead to customer complaints, returns, and damaged brand reputation.

Surface Growth

Visible microbial growth on the surface of stored materials is a clear sign of contamination. Bacteria, mold, and fungi can form colonies, leading to issues such as:

  • Biofilm formation – A protective microbial layer that makes contamination harder to remove.
  • Black or green mold patches – Common in humid storage conditions.
  • Slime layers – Bacterial byproducts that can cause clogging in pipes or filters.

Surface contamination is not just aesthetic—it can alter product performance, making coatings streaky, adhesives ineffective, and emulsions unstable. Additionally, once a biofilm forms inside manufacturing equipment, it becomes highly resistant to standard cleaning procedures, requiring aggressive treatments that can damage machinery.

Product Instability & Separation

Microbial activity can lead to chemical imbalances, causing product separation or instability. Bacteria and fungi consume stabilizers, surfactants, and preservatives, leading to:

  • Phase separation – Water and oil-based components separating in emulsions.
  • Sedimentation – Insoluble particles settling at the bottom of storage containers.
  • Foaming issues – Increased gas production causing excessive foaming during mixing.

In industries such as paints, coatings, and adhesives, stability is a key quality parameter. Contaminated products may fail internal quality tests, leading to large-scale waste and financial losses.

Regulatory Non-Compliance

Many industries must comply with strict microbial contamination limits, especially those governed by:

A product that fails microbial limits may require a complete batch recall, resulting in:

  • Regulatory penalties and legal action
  • Loss of market trust and brand reputation
  • Supply chain disruptions and financial setbacks

Onnovo’s PHMP ensures compliance by integrating preventative hygiene measures and advanced microbial control solutions, helping manufacturers avoid costly non-compliance issues.

Prevent These Issues with Onnovo’s OPHP
