ASTM D4265 Evaluating Stain Removal Performance in Home Laundering

ASTM D4265 is a standard test method developed by ASTM International. It outlines procedures for evaluating the stain removal performance of laundry detergents. This test method provides a systematic way to assess the effectiveness of different laundry detergents in removing most stains commonly encountered in regular loads of laundry. The purpose of ASTM D4265 is to establish a consistent and reproducible way to compare the cleaning power of different laundry detergents to remove stains.

The test involves creating standardized fabric swatches using stubborn stains such as coffee, red wine, chocolate, as well as other stains as requested by the client. These stained swatches are then laundered in a medium load or large load along with uncontaminated control swatches using the laundry detergent being tested. After washing, the swatches are assessed visually or instrumentally to determine the degree of stain removal.

HCPA DCC-11 Home Laundering Pre-Wash Spotter Stain Removal

HCPA DCC-11 is a test method developed by the Household & Commercial Products Association (HCPA). It focuses on evaluating the performance of pre-wash spotter products used for stain removal in home laundering. The abbreviation “DCC” stands for “Detergent and Cleaning Product Division,” which is a part of the HCPA responsible for developing standards for household cleaning products.

Pre-wash spotter products are not simply a concentrated detergent, rather they are specialized stain removers applied directly to stains on clothing or fabrics before washing. These products are designed to help break down and remove stubborn or specific stains that might not be effectively addressed by regular liquid detergents or powdered detergents alone. HCPA DCC-11 outlines a standardized procedure for evaluating the effectiveness of these pre-wash spotter products in removing a variety of stains commonly encountered in household settings. The test method typically involves (1) Stain Application; (2) Treatment with Pre-Wash Spotter; (3) Laundering; (4) Stain Removal Evaluation.

EPA Safer Choice

Many national retailers reserve prime space on their store shelves for consumer products that meet some standard of eco friendliness. At Dell Tech, we can test your laundry detergent for the purpose of eco-label certification. One of the eco label certifications we test for is the EPA Safer Choice standard. This is a program established by the United States Environmental Protection Agency (EPA) to guide consumers and businesses towards products that are safer for human health and the environment. EPA Safer Choice is a voluntary program aimed at helping consumers make informed choices by identifying products that are free from harsh chemicals.

Products carrying the Safer Choice label have undergone a rigorous evaluation process. The EPA evaluates the ingredients in these products, focusing on factors such as toxicity, biodegradability, and potential harm to aquatic life. Products that meet the Safer Choice standard must demonstrate reduced risk to people and the planet compared to conventional alternatives. Some of the safest laundry detergents use plant based ingredients, although this is not always the case.

Green Seal

Dell Tech can support your eco friendly business goals with the following 2 tests for your laundry detergent:

  • Green Seal GS-48 Laundry Care Products for Household Use
  • Green Seal GS-51 Laundry Care Products for Industrial and Institutional Use

Ecolabel performance testing can help you demonstrate that your product is a non toxic laundry detergent according to certain criteria. It can also certify that your brand prohibits animal testing (cruelty free) or the use of artificial fragrances. Finally, it offers a means to substantiate that your laundry detergent performs as well as other traditional chemical products available in the market.

I knew very little about the process of getting it approved by Health Canada, and took a chance contacting your company for help after a quick search on Google. It was a fortunate decision.  After a brief phone conversation, Joe knew exactly what we needed and made the entire process seem effortless. I’ve worked with a lot of consultants, he is by far one of the best!"

What is claims testing?

Claims testing (substantiation) is the process of providing evidence to support the claims made about a product in advertising, marketing or promotional materials. For consumer products like laundry detergents, companies put their products through claim testing to substantiate claims made about their product’s benefits, features and performance.

Claims testing ensures that that claims are accurate and truthful by providing support in the form of scientific evidence or data. This process helps to prevent false or misleading advertising. It also protects consumers from making purchasing decisions based on inaccurate or exaggerated claims.

What are the detergent testing methods for proving product performance?

One of the laundry stain removal tests performed at Dell Tech is ASTM D4265 Standard Guide for Evaluating Stain Removal Performance in Home Laundering. This test is used on the following laundry products:

  • Liquid detergent
  • Powder detergent
  • Laundry soda
  • Laundry soap
  • Washing powder
  • Stain remover
  • Pre-wash treatment

ASTM D4265 determines a laundry detergent’s cleaning efficiency by its ability to remove standard stains. Our lab uses standard washing machines to closely mimic the consumer experience at home. Here is a list of standard stains used to evaluate a product’s cleaning performance in ASTM D4265:

  • Peat
  • Animal fat/red dye
  • Motor oil
  • Red wine
  • Dessert (chocolate)
  • Grass
  • Butter
  • Curry
  • Blood
  • Beta-carotene
  • Clay
  • Make-up
  • Tomato sauce
  • Tea
  • Baby food

Do I need claim substantiation for my laundry detergent?

Yes. Claim substantiation is important for your laundry detergent or any other consumer product. If you’re making specific claims about the benefits, features, or performance of your laundry detergent in your advertising, marketing materials, or product labeling, it’s essential to have evidence to back up those claims.

For example, if you’re claiming that your laundry detergent is “100% effective in removing tough stains” or “environmentally friendly and biodegradable,” you would need to provide evidence that supports these claims. This evidence could include:

  1. Test data to support to the effectiveness of your laundry detergent in removing stains
  2. Data showing your detergent’s ingredients and their biodegradability properties for ecolabel certification
  3. Comparative studies showing how your product performs better than or as well as competing brands

By having proper claim testing completed by a trusted 3rd party lab like Dell Tech, you can avoid legal issues, build credibility and trust with your customers, and ensure that your marketing accurately represents the qualities of your laundry products.
