Laundry-VR ™

A professional digital tool to process, analyse, visualise and communicate

laboratory washing results with a consumer-centric approach


It shows what consumers would see when evaluating washing results in diverse visual scenarios, where garments are washed, stored or used—validated and verified.

It includes perceptual thresholds to represent how consumers discriminate satisfaction in cleanliness, whiteness and colour-care.

It works for different regional consumers around the world, different laundry experiences, different cultures.

It combines cutting-edge concepts in fluorescent spectroscopy, colour appearance models, colour reproduction and WebXR technologies. It is the most advanced scientifically-based digital tool in the detergency field.

In blending with VR-Clicks (the digital tool to collect consumer responses), they offer the most modern and advanced approach to represent the interaction between consumers with products and products' performance in relevant visual scenarios.

Since November 2021, the application has included the Stain Removal Index in Virtual Realities (SRI-VR), the most advanced representation of cleanliness perception considering garment irregularities/textures in virtual visual scenarios.



Is this for my team or me?

  • Yes, if you or your team are responsible for deciding about brand claims based on washing performance. Which ones? How to support them?

  • Yes, if you or your team are responsible for formulation design, formulation cost, margins, selection of materials/ingredients, balance consumer benefits with laundry technologies in the area of cleanliness, whiteness and colour-care



What input data do I need from my detergency laboratory?

  • Two (2) spectral data from each fabric surface before and after some washing process, without and with UV cutting filter, if your lab has a spectrophotometer with the two filters option, or

  • One (1) spectral data from each fabric surface before and after some washing process, could be without or with UV cutting filter, if your lab has a spectrophotometer with no UV filter option, or

  • One (1) set of colorimetric values like L*, a*, b* from each fabric surface before and after some washing process, if your lab has only a colorimeter, or

  • One (1) set of tristumulus values like X, Y, Z from each fabric surface before and after some washing process, if your lab has only a colorimeter, or

  • Contact us to see other options or to clarify specific needs.

SRI-VR. What is new?

The new Stain Removal Index in Virtual Realities (SRI-VR) is the unique feature of Laundry-VR. It combines cleanliness lab readings with consumer-relevant garment's irregularities/textures and dinginess levels for the first time in the industry. Now shadows, creases, bottoms, seams, and redeposition of body and other soils are considered to quantify cleanliness perception.

The new SRI-VR aligns with the final perception of cleanliness in actual clothes and scenarios when consumers evaluate washing results. The last values are between 2 to 5 units higher than the original lab readings.

How is it calculated? Four (4) different consumer-relevant garments are rendered, each with a different stain location and dinginess level. The remanent stained area and its proximal field are characterised by the appropriate RGB values, which are transformed to colorimetric attributes and then the SRI is calculated. See the below graphs.

Main implications:
  1. Reach more sustainable goals. In the current paradigm of non-consumer relevant detergency studies (consumer irrelevant test monitors, lab protocols and readings), new sustainable and environmentally friendly materials appear costly and have less performance. Changing the paradigm to a more consumer-centric approach using tools like SRI-VR will uncover sustainable options that offer enough performance to consumers with no detriments in the brand’s margins.
  2. Expand the cleanliness related brand' claims. New evidence appears when using consumer-relevant dingy monitors capable of being nearly thoroughly washed in the first wash in combination with SRI-VR, which quantify the level of stain remotion as consumers perceive in the actual garment visual environment. Consumers will probably link more brands’ claims to tangible benefits.
  3. Balance of ingredients and margins improvements. Evaluating formulation’s ingredients with a consumer-centric approach helps balance product’s margins in two ways: prescinding of materials with no consumer's benefit, and including materials with apparently low consumer benefit. In the end, reaching the final purpose to balance business profits with consumer's benefits perception in actual diverse and flexible regional laundry scenarios.

Laundry-VR terms and definitions
  • Modality. Adopted whites in the visual scenarios. Options:
    • PROPER. The adopted white is the original white fabric, before it becomes the dingy surrounding in stained dingy monitors
    • STANDARD, BRIGHT, BLUE or GREEN. Different white fabrics without or with shading dyes, selected as adopted whites in relevance to some specific laundry market
  • Source of illumination - Categorical observer. Combination of three parameters: observer field of view, source of illumination in the visual scenario, categorical observer age. Options:
    • FV_2 or FV_10. Field of view: 2 degrees for cleanliness studies and 10 degrees for whiteness or colour-care studies
    • ILLCFL. Source of illumination: compact fluorescent lamp. Nearly no presence of UV light
    • ILLD65. Source of illumination: exterior daylight, equivalent to D65. Moderate relative UV light
    • ILLID65. Source of illumination: interior daylight, equivalent to ID65. Low relative UV light
    • ILLD150. Source of illumination: exterior daylight, equivalent to D150. High relative UV light
