Campo Research’s Response to Social Media Misinformation and Taiwan Food and Drug Administration (TFDA) allegation concerning Sudan IV presence in Campo Siddha Vepuvillai Karushalai Yenai. Comprehensive Report on Independent Laboratory Findings and Explanatory Analysis, TFDA’s Lack of Procedural Fairness, and Legal Actions Initiated by Campo Research against TFDA.

Introduction

On January 16, 2026, Campo Research issues this formal statement in response to Social Media Misinformation and the Taiwan Food and Drug Administration’s (TFDA) recent claim concerning the alleged presence of Sudan IV, a prohibited colourant, in cosmetic raw material – Campo Siddha Vepuvillai Karushalai Yenai. Campo Research categorically denies the presence of Sudan IV in its products and asserts that the Social Media and TFDA’s allegations are unfounded. This document provides detailed evidence from recent batches testing, outlines Campo Research’s communications with TFDA, analyses Social Media Misinformation, highlights procedural shortcomings in TFDA’s approach, addresses the reputational damage sustained, and details legal actions undertaken by Campo Research against TFDA.

Analysis of Social Media Misinformation Regarding Campo Research’s Campo Siddha Vepuvillai Karushalai Yenai

Recent allegations circulating on Chinese social media platforms and through various news outlets and false news outlets have raised concerns about the integrity of Campo Research’s cosmetic raw material – Campo Siddha Vepuvillai Karushalai Yenai, specifically regarding Sudan IV contamination. These claims have contributed to widespread misinformation, particularly targeting Campo Research in the lead-up to China’s Singles Day shopping event in 2025. Crucially, neither TFDA, Dad’s Lab, nor media representatives initiated any direct communication with Campo Research to verify the veracity of these allegations prior to publication.

Comprehensive analytical testing using HPLC-DAD (High-Performance Liquid Chromatography with Diode-Array Detection) was conducted on multiple batches of cosmetic raw material – Campo Siddha Vepuvillai Karushalai Yenai supplied by Campo Research to China and Taiwan during 2024 and 2025 (17 batches and links to test results are included). The test results, as detailed in the enclosed reports, consistently showed negative findings for Sudan IV, confirming the absence of this contaminant in all batches tested. These reports provide transparent and scientifically robust evidence supporting the safety and compliance of Campo Research’s Campo Siddha Vepuvillai Karushalai Yenai.

Notably, Dad’s Lab conducted independent analyses that revealed abnormally high concentrations of Sudan IV in samples purportedly associated with Campo Research, suggesting possible ‘deliberate tampering’. The evidence strongly indicates that such adulteration is likely attributable to certain suppliers operating within China and Taiwan, where similar raw materials are available at significantly lower costs. This finding raises concerns about the motivations behind the misinformation campaign and underscores the importance of rigorous supply chain oversight.

In summary, the spread of false information regarding Sudan IV contamination in Campo Research’s Campo Siddha Vepuvillai Karushalai Yenai appears to be a targeted campaign coinciding with a major commercial event. The failure of relevant authorities, laboratories, and media outlets to seek direct verification from Campo Research undermines the credibility of these claims and highlights the need for transparent industry communication. The enclosed test reports substantiate Campo Research’s commitment to product integrity and regulatory compliance, offering clear evidence against the circulated allegations.

Investigation and Findings

Upon learning of the allegations raised by the Taiwan Food and Drug Administration (TFDA), Campo Research conducted a thorough internal investigation and wishes to clarify the following key points:

1. Source of Samples: All samples seized and tested by TFDA originated from another company, EHO Co., and were not supplied directly by Campo Research.
2. Lack of Direct Communication: TFDA did not contact Campo Research at any point to request samples for independent verification.
3. Basis for TFDA Conclusion: TFDA based their determination on samples seized from EHO Co., relying solely on EHO Co.’s claim that these samples were originally from Campo Research.
4. Absence of Testing Reports: TFDA has not provided any testing reports or documentation to Campo Research regarding the seized samples.
5. Unverified Chain of Custody: To date, there has been no verification that the samples provided to TFDA by EHO Co. were originally sourced from Campo Research.
6. Potential Adulteration: There is no confirmation as to whether the seized samples may have been adulterated by EHO Co. with ingredients from other companies.

Summary of Testing: Independent Laboratory Results

Campo Research, upholding its commitment to product safety and regulatory compliance, commissioned an accredited independent laboratory to conduct rigorous analysis of the cosmetic raw material in question (Campo Siddha Vepuvillai Karushalai Yenai). The analytical method employed was High-Performance Liquid Chromatography with Diode Array Detection (HPLC-DAD), a gold-standard technique for the detection of Sudan IV and related compounds.

• All 17 batches of Campo Siddha Vepuvillai Karushalai Yenai tested negative for Sudan IV. No trace of the prohibited substance was detected in any sample.
• The tests were performed by an accredited third-party laboratory, ensuring methodological reliability and data integrity.
• Full documentation of the test results, including chromatograms and certificates of analysis, are attached below for reference.

PLEASE SEE ATTACHED 17 TEST REPORTS

These findings unequivocally demonstrate the absence of Sudan IV in Campo Siddha Vepuvillai Karushalai Yenai supplied by Campo Research.

Explanatory analysis – FTIR of Sudan IV (CI 26105) reference standard vs Campo Siddha Vepuvillai Karushalai Yenai (Batch lot# 2025-06-20)

A crude numerical comparison of the two FTIR spectra (based on their plotted profiles) gives a similarity match score of 1.80%, whereas genuine FTIR library matches for the same compound are typically ≥90 – 95%. On this basis, the Campo Siddha Vepuvillai Karushalai Yenai (Batch lot# 2025-06-20) sample is spectroscopically incompatible with Sudan IV reference standard.

Where Sudan IV reference standard has multiple sharp peaks in the 1600-450 cm⁻¹ region, the Campo Siddha Vepuvillai Karushalai Yenai (Batch lot# 2025-06-20) sample does not show those features. Instead, it has its own distinct, much simpler pattern. The peak positions and overall band pattern of Campo Siddha Vepuvillai Karushalai Yenai (Batch lot# 2025-06-20) do not coincide with Sudan IV reference standard.

The ‘Sudan IV positive’ results obtained from the media reports and claims may be based on retention time and UV detection, as the overlaid FTIR spectra show that the Campo Siddha Vepuvillai Karushalai Yenai (Batch lot# 2025-06-20) (red trace) and pure Sudan IV reference standard (black trace) are spectroscopically dissimilar (1.80% similarity vs ≥90% expected for true identity matches). The diagnostic fingerprint bands of Sudan IV reference standard are not present in the Campo Siddha Vepuvillai Karushalai Yenai (Batch lot# 2025-06-20) sample spectrum. This indicates that the HPLC peak most likely corresponds to a co-eluting Campo Siddha Vepuvillai Karushalai Yenai rather than Sudan IV, and the original result of ‘Sudan IV positive’ should be interpreted as a false positive.

HPLC (with UV detection) mainly sees chromophores. Many natural lipophilic pigments can have similar retention time and/or similar UV-vis λmax to Sudan IV. Thus, many natural lipophilic pigments (e.g. carotenoids, anthraquinones, other natural chromophores) can co-elute with Sudan dyes and show similar UV-vis maxima, particularly in the 450–550 nm region.

When Campo Siddha Vepuvillai Karushalai Yenai (red trace) is overlaid and compared directly to the Sudan IV reference standard (black trace):

The unique and distinct aromatic/azo-related bands of Sudan IV reference standard in the 1600-1500 cm-1 region and near ~750 cm-1 are not observed in Campo Siddha Vepuvillai Karushalai Yenai spectra. Instead, Campo Siddha Vepuvillai Karushalai Yenai spectra is dominated by broad lipid/ester features, particularly a strong ester C=O band at 1741 cm-1 and intense CH2 stretches, which are not dominant features of Sudan IV reference standard.

IN CONCLUSION, if Sudan IV were present at a structurally significant level, its characteristic sharp aromatic bands would be superimposed on the lipid background, which is not the case. Campo Research reiterates that Campo Siddha Vepuvillai Karushalai Yenai does not contain Sudan IV.

Campo Research’s Response to TFDA’s Allegation

Since being informed of TFDA’s allegation, Campo Research has consistently and transparently communicated its disagreement with the assertion that Campo Siddha Vepuvillai Karushalai Yenai contain Sudan IV. Multiple attempts have been made to engage with TFDA officials and request:

• Disclosure of the test reports and analytical data supporting the TFDA’s allegation;
• Clarification regarding the chain of custody and verification of the origin of the seized materials attributed to Campo Research;
• Opportunities for independent verification and retesting in the presence of both parties.

To date, TFDA has not responded to these communications, nor has it provided any substantiating test reports or data. The absence of transparency and engagement on TFDA’s part is of significant concern, particularly given the seriousness of the allegations and their impact.

Procedural Concerns Regarding TFDA’s Investigation

Campo Research notes several procedural deficiencies in TFDA’s handling of this matter:

• TFDA has failed to produce the original test reports or disclose the analytical methodology utilised to detect Sudan IV.
• No evidence has been provided to verify the chain of custody or the integrity of the raw materials seized from EHO Co., allegedly linked to Campo Research.
• The provenance and storage conditions of the seized materials have not been substantiated, raising questions regarding potential contamination, adulteration or misidentification.

These shortcomings undermine confidence in the validity of TFDA’s findings and call into question the procedural fairness of the investigation.
