Wellness Brand Ensures Natural Color Stability with HunterLab Vista
A leading wellness products manufacturer—spanning nutritional, pharmaceutical, personal care, and household cleaning categories—wanted a more objective, quantitative method to measure the color of its liquid soaps.
As the company transitioned from artificial to natural dyes, it began noticing color changes over time that could affect consumer perception and brand consistency. The internal Quality Assurance (QA) lab needed a precise, repeatable way to track color shifts for uniformity testing and shelf-life validation.

The Challenge: Tracking Subtle Color Changes Over Time
Natural colorants are more environmentally friendly—but also more variable.
Without advanced instrumentation, it was difficult to:
- Detect gradual color degradation during storage.
- Ensure uniform color across production batches.
- Establish objective quality standards as dyes naturally oxidized or settled.
- Quantify shelf-life stability, since visual checks were subjective and inconsistent.
The QA team needed a scientific, repeatable approach that could accurately monitor color change over time in a translucent liquid matrix.
The HunterLab Solution: Vista Spectrophotometer
HunterLab recommended the Vista Spectrophotometer — designed for transparent and semi-transparent liquids, providing simultaneous color and haze measurement.
Using 10 mm cuvettes/cells and optional sealed caps, the customer could easily store retains and perform periodic re-measurement to monitor color degradation over time.
During a virtual demo, HunterLab’s application specialists demonstrated:
- How to properly fill the cells to avoid air entrapment; allowing 5–10 minutes for bubbles to dissipate before measurement.
- How to use EZ View with Color Plot, enabling instant visualization of where each soap sample resides in color space relative to its target.
- Best practices for consistent sample presentation, ensuring repeatable results across days or batches.
The Vista’s compact benchtop design and touchscreen interface allowed the QA team to perform tests quickly, visualize trends immediately, and establish measurable internal color standards.
Outcomes: Objective Color Control, Natural Dye Confidence
By integrating HunterLab Vista into their QA process, the wellness manufacturer achieved:
- Accurate, repeatable color measurements for natural-dye formulations.
- Objective tracking of color changes during storage and aging.
- Faster quality assurance with real-time color visualization in EZ View.
- Reduced waste and rework by identifying instability early.
- Increased confidence in natural color uniformity, strengthening sustainability goals and consumer trust.
