A Case Study on Unlocking True Consumer Emotion in Product Testing

Introduction

In the highly competitive FMCG and personal care industry, product success depends not just on functionality, but on sensory experience and emotional resonance.

Fragrance, in particular, is one of the most complex elements to evaluate. Consumers often struggle to articulate what they feel, leading to gaps between stated feedback and actual perception.

A leading global consumer goods company partnered with Entropik to address this challenge. The objective was to evaluate a new fragrance formulation (ESA 67) and understand:

  • Emotional response during first exposure

  • Scent perception and associations

  • Distinctiveness and recall potential

  • Impact on purchase intent

To achieve this, the study combined diary-based qualitative research with Decode’s multimodal AI analytics.

Business Challenge

The brand needed to answer a critical question:

Does the new fragrance create a strong enough emotional and sensory impact to drive purchase?

Traditional research methods were insufficient because:

  • Consumers used generic descriptors such as “fresh” or “pleasant”

  • Feedback lacked clarity and specificity

  • Emotional signals were subtle and difficult to quantify

This created uncertainty around:

  • Product differentiation

  • Brand positioning

  • Market readiness

Research Methodology

The study leveraged a diary-style product testing approach enhanced with multimodal consumer analytics.

Approach

  • Blind product testing with 26 consumers

  • Diary-based feedback capturing real-time experiences

  • Multimodal data collection including:

    • Facial expressions

    • Voice tonality

    • Text sentiment

Why Multimodal Matters

Traditional methods rely heavily on what consumers say. However, emotional responses are often:

  • Subconscious

  • Difficult to verbalize

  • Influenced by social bias

Decode’s multimodal framework captures:

  • Unfiltered emotional signals through facial coding

  • Cognitive and emotional intensity through voice analysis

  • Conscious perception through language

This enables a holistic understanding of consumer experience.

Key Findings

1. High Acceptability, Low Differentiation

Consumers consistently described the fragrance as:

  • Gentle

  • Fresh

  • Floral and slightly fruity

While this indicates broad appeal, it revealed a significant limitation:

The fragrance lacked a distinctive identity.

Consumers struggled to:

  • Clearly define the scent

  • Associate it with a unique memory

  • Identify a dominant note

This reduced its ability to stand out in a competitive market.

2. Emotional Engagement Was Underestimated

Voice-only analysis suggested:

  • 89% neutral emotion

  • 3% positive emotion

However, multimodal analysis revealed:

  • 23% positive emotion

  • 72% neutral

  • 5% negative

This indicates that:

Consumers were more positively engaged than traditional methods suggested.

Facial expressions and behavioral cues captured emotional signals that were not reflected in verbal responses.

3. Neutrality Masked Consumer Uncertainty

A dominant neutral response does not necessarily indicate satisfaction.

In this case, neutrality reflected:

  • Lack of strong emotional connection

  • Ambiguity in scent perception

  • Difficulty in categorization

Consumers described the fragrance as:

  • Pleasant but indistinct

  • Familiar yet undefined

This ambiguity directly impacted product recall and differentiation.

4. Weak Purchase Signals

Despite being acceptable, the fragrance failed to generate strong purchase intent.

Key reasons:

  • No clear olfactive identity

  • Low memorability

  • Limited emotional anchoring

As highlighted in the study:

  • Consumers appreciated the scent but did not feel compelled to choose it over alternatives

Critical Insight for Businesses

This case highlights a key principle in product development:

Consumer liking does not guarantee commercial success.

Products must deliver:

  • Distinctiveness

  • Emotional resonance

  • Clear sensory identity

Without these, even well-received products risk underperformance in the market.

Impact of Multimodal Insights

By integrating diary-based research with Decode’s AI capabilities, the brand was able to:

Uncover Hidden Emotional Signals

Identify positive engagement that was not captured through traditional feedback

Diagnose Product Weaknesses

Pinpoint lack of scent differentiation as the primary barrier

Improve Decision Confidence

Move from subjective interpretation to data-backed insights

Strategic Recommendations

Based on the findings, the brand identified clear optimization directions:

1. Strengthen Scent Signature

Introduce a dominant note to improve recall and differentiation

2. Enhance Emotional Anchoring

Create stronger associations to drive memory and preference

3. Balance Subtlety with Impact

Retain the gentle profile while increasing depth and character

Why This Matters for Enterprise Research Teams

For businesses in FMCG, beauty, and personal care, this case demonstrates:

Limitations of Traditional Research

  • Over-reliance on verbal feedback

  • Inability to capture subconscious responses

  • Risk of misinterpreting neutrality

Value of Multimodal Consumer Insights

  • Captures real emotional engagement

  • Reduces bias and ambiguity

  • Enables faster, more accurate product decisions

How Decode by Entropik Enables Better Product Decisions

Entropik’s Decode platform combines:

to help enterprises:

  • Measure real consumer emotions at scale

  • Analyze product experience beyond stated feedback

  • Optimize formulations before market launch

  • Improve success rates of new product introductions

Conclusion

This case study reinforces a critical shift in market research:

Understanding consumers requires going beyond what they say to what they feel.

By integrating diary-based methodologies with multimodal AI, businesses can:

  • Identify hidden risks early

  • Enhance product differentiation

  • Build stronger consumer connections

For enterprise brands, this approach is no longer optional. It is essential for delivering products that succeed in increasingly competitive markets.
