Coloration of a product so that it has minimal staining properties when in contact with other items is a unique and challenging goal which requires a unique colorant — Organic Dyes and Pigments’ OrcoTint™ NS dyes are polymeric highly concentrated liquid colorants designed to minimize staining on many different industry end-products such as detergents & soap, chemical compounding products, ice-melts, portable toilet chemicals, agriculture & livestock colorants, Identification Agents,  and many environmentally “green” application items. OrcoTint™ NS colorants provide minimal or virtually no staining on skin, textiles, plastics, and processing machinery.  This line of colorants is compatible with many systems due to its non-ionic chemical nature and high water-solubility.  Their high solubility allows them to be formulated in high dosages in both liquid and solid applications.  Beyond the standard OrcoTint™ NS line, custom-formulated colors can be developed according to your specific shade and physical property requirements.  Current OrcoTint™ NS colorants available consist of the OrcoTint™ NS Royal Blue, Blue, & Violet.  New colorants are currently being developed to offer a complete palette of colors.

Portable Toilets & Sinks, Sanitation,  & Marine / RV industries find the OrcoTint™ NS line of colorants very suitable for the coloration of sanitation chemicals because of their ease-of-use, high solubility, high-temperature stability, and being environmentally friendly.   Fragrances are easily added to the chemical formulations helping to mask odors.  These colorants are used extensively in products such as gel-packets, fast-dissolving tablets, deodorizers, foaming hand sanitizers, RV laundry packets, and portion-control tablets & packets.  Many OrcoTint™ NS-colored  deodorizing chemicals are also used in municipality landfill & transfer stations and portable restrooms used at events and construction sites.


Detergents & Soap formulations typically include OrcoTint™ NS colorants to minimize staining on skin, textiles, plastics, concrete, ceramics, and processing machinery.  Products formulated using OrcoTint™ NS colorants include hand sanitation products, foaming soaps, laundry detergent & softeners, and industrial & household cleaning products.  OrcoTint™ NS colorants are used extensively in liquid, powder, and gel-pack formulations.


Ice-Melt & De-Icing Coloration aids in the visual identification of icy areas that have been treated.  With safety being a primary concern in areas such as stairways, pedestrian sidewalks, parking lots, and industrial loading areas, OrcoTint™ NS colorant-treated ice-melts help to minimize dangerous hazards.   OrcoTint™ NS colorants are the preferred ingredient in ice-melt formulations as they have minimal-to-no staining characteristics when in contact with concrete, asphalt, brick, wood, clothing, shoes, leather, & carpet, and are  highly concentrated, environmentally friendly to vegetation, easy-to-use, and visually appealing.   They are also non-reactive to salts and are stable in rock salt, calcium chloride, sodium chloride, potassium chloride,  calcium magnesium acetate, and magnesium chloride formulations.


 Livestock Identification  is a common practice to temporarily mark and identify livestock for many reasons.  Some include herd management and treatment codes for medical, insemination, feeding, milking, and monitoring.  OrcoTint™ NS   colorants easily wash off and are safe for use on animals and the environment.NS- Livestock Marking


Agriculture  OrcoTint™ NS are useful colorants in the Seed Treatment, Crop Protection, & Fertilizer industries.  These colorants may be used in the coloration of many seed treatment coatings, fertilizer, fungicide, pesticide, & herbicide treatments, nitrogen stabilizers, urease inhibitors, and other agricultural chemical treatments to act as a visual product identifier for product branding and application, health, & safety awareness.  It is important that Codes of Federal Regulations(CFRs) are understood and adhered to when coloring agricultural products.  These codes include 40 CFR 180.91040 CFR 180.92040 CFR 153.155, and EPA’s Federal Insecticide, Fungicide, and Rodenticide Act(FIFRA).


Spray Pattern Indicator Agents are formulated in many instances using OrcoTint™ NS colorants due to their minimal-to-no staining characteristics and ability to wash off easily.  A highly visible “temporary marking” system is desired in many applications such as fertilizer/pesticide/herbicide spraying, turfgrass markings, and industrial & aquatic vegetation management.


Custom Chemical Compounding requires a wide variety of colorants with different physical properties and characteristics.  Typically, a chemical is colored mainly for identification, marketing, and branding purposes.  This is where OrcoTint™ NS colorants fit the bill — they are non-ionic making them chemically compatible in many formulations, are minimally staining or virtually non-staining to many materials, have a wide temperature stability range, and are highly concentrated.  Some chemical formulations where OrcoTint™ NS colorants are typically used are industrial cleaners, antifreeze, heat-transfer fluids, and rust inhibitors for the water treatment, mining, HVAC, coatings, geothermal, and oil & gas industries.

Actual OrcoTint NS™ samples must be evaluated in a laboratory on medium to be colored in production for accurate shade, physical properties, and degree of non-staining results. Shades shown on print material and computer monitors are for general reference only as they are inherently inaccurate due to calibration variations and technical limitations of monitors and printers.
