PREVENTOL ON-S

Preventol ON-S is an in-can preservative and product protection biocide used to control bacteria, fungi, and yeast in water-based industrial formulations.
Preventol ON-S helps prevent spoilage effects such as odor formation, viscosity loss, gas formation, discoloration, and microbial slime, supporting longer shelf life and consistent product quality.
Preventol ON-S is typically supplied as a liquid biocide preparation for easy incorporation into coatings, dispersions, adhesives, and related waterborne products, but Preventol ON-S must be used according to local biocide regulations and handled with appropriate safety measures due to irritation and sensitization potential.

Preventol ON-S is valued because Preventol ON-S helps maintain product quality, extends shelf life, and reduces spoilage-related complaints in many water-based industrial products.

DESCRIPTION

Preventol ON-S is an in-can preservative intended to protect formulated products, and Preventol ON-S works by inhibiting microbial growth in aqueous media.
Preventol ON-S is typically dosed at low levels, and the effective use level depends on pH, temperature, raw material contamination, and the intended shelf life target.
Preventol ON-S should be added with adequate mixing to ensure uniform distribution, and Preventol ON-S is often added during the final stage to reduce exposure to harsh processing conditions that can reduce biocide activity.

Preventol ON-S performance can be influenced by formulation components such as surfactants, thickeners, pigments, and reducing agents, so compatibility screening is recommended.
Preventol ON-S may be less effective in strongly alkaline or strongly reducing environments, so the preservation strategy should be optimized for challenging systems.
Preventol ON-S is designed for product preservation, and Preventol ON-S should not be confused with dry-film preservatives that protect cured coatings from surface mold.

Preventol ON-S can cause skin sensitization in susceptible individuals, so Preventol ON-S should be handled with appropriate PPE and exposure controls.
Preventol ON-S should be stored in original tightly closed packaging and protected from extreme temperatures to maintain stability.
Preventol ON-S must be used in compliance with local biocide regulations and labeling requirements for the target market and product category.

FIRST AID

Inhalation:
Move to fresh air if vapors or mists are inhaled.
Seek medical attention if respiratory symptoms persist.
Avoid breathing aerosols during high-shear mixing and spraying operations.

Skin Contact:
Remove contaminated clothing and wash skin thoroughly with soap and water.
Seek medical attention if irritation, rash, or sensitization symptoms develop.
Do not reuse contaminated clothing until it has been washed.

Eye Contact:
Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation persists.

Ingestion:
Rinse mouth with water and do not induce vomiting.
Seek medical attention promptly if a significant amount is swallowed.
Never give anything by mouth to an unconscious person.

Note to Physicians:
Treat symptomatically.
Skin sensitization potential should be considered if dermatitis develops.
Provide supportive care based on exposure route and symptoms.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including chemical-resistant gloves and safety glasses or goggles.
Avoid skin contact and avoid generating mists, and wash hands after handling.
Do not eat, drink, or smoke in handling areas, and maintain good industrial hygiene practices.

Ventilation:
Use general ventilation for normal handling.
Use local exhaust where aerosols or mists can be generated during mixing, pumping, or spraying.
Avoid confined areas where vapors or mists may accumulate.

Storage:
Store in tightly closed original containers in a cool, dry, well-ventilated place.
Protect from freezing and from excessive heat, and keep away from direct sunlight.
Keep away from incompatible chemicals that may deactivate biocides or cause decomposition (system dependent).

Spill and Leak Procedures:
Contain the spill and absorb with inert material.
Collect into suitable containers for disposal according to local regulations.
Wash the contaminated area with water while preventing slip hazards on wet surfaces.

Handling Precautions:
Confirm the effective dose in the finished formulation using microbial challenge testing where appropriate.
Verify compatibility with pH, thickeners, pigments, and reducing agents to avoid loss of preservative efficacy.
Rotate stock using FIFO practices to maintain consistent quality and predictable preservation performance.
