The production and manufacturing of gloves are largely unregulated, with limited and infrequent glove polymer migration testing

The Delta Zero™ verified badge certifies a range of our U.S. nitrile gloves, which have been thoroughly tested and passing stringent glove standards; adhering to the highest level of consistent glove safety and performance.

Third-party laboratory testing ensures the consistent quality and safety of these glove’s raw materials and the absence of unsafe chemicals, toxins and microbial contaminants - areas that can pose a threat to multiple industries and glove user health.

The hidden risks of glove contamination result from the largely unregulated production and manufacturing of single-use gloves, with limited and infrequent glove compliance testing on import to New Zealand and the U.S.

Delta Zero’s multi-layered proprietary glove testing is outlined below. 

5 Factor Food Safety & Performance Verification 


The chemical signature of glove raw material “ingredients” are tested to ensure consistency of manufacturing and that they do not contain potentially toxic chemicals which could impact food and medical safety and glove user health.

Test: Gas Chromatography Mass Spectrometry (GC / MS)

Ultimately, these solvent extractions and toxic chemical tests provide an analysis of the glove raw material “ingredients”, and future test comparisons will ensure consistency of glove polymer composition and quality. 


Specific glove types can affect the risk of pathogen cross-contamination.

Test: Physical Chemistry
The surface tension of liquids (or semi-solids) were studied relevant to the tested surface free energy of Eagle glove surfaces. This work identifies cross-contamination pick-up and transfer potential for glove surfaces with respect to both spoilage and pathogenic species in various food and human soils.


Bioburden on both the inside (skin contact) and outside (food and patient contact) of gloves are tested to ensure against fungal and microbial contaminants that could pose a threat to the product or person handled or the glove wearer.

Test: Microbial Analysis
These tests provide a specific profile in respect to how our gloves are manufactured, to ensure against contamination, whether accidental, human, process-related or intentional.


Glove type, quality and acceptable quality level (AQL) can affect the microbial contamination, and the possibility of glove particle contaminants in food.

Test: AQL, Strength & Elongation, Puncture Resistance
Structural integrity tests verify Eagle gloves exceed medical grade AQL requirements, ensuring against contamination through pinhole defects. Quality raw material ingredients ensure higher strength and resistance to puncture.


The gloves are tested for chemical and toxic exposure, to ensure against skin irritation and occupational skin diseases of the wearer.

Test: In Vitro Cytotoxicity Analysis
The analysis detects toxicity from a wide variety of chemicals that would result in a dermal cell or systemic toxicity, indicating the biocompatibility of glove surfaces.

Our sensitive dual cell assay system detects chemicals or conditions consisting, but is not limited to: pesticides, microbial contaminants, endotoxins, glycols, detergents/soaps, oils, other than optimal pH, phthalate plasticisers, bisphenol A (BPA), heavy metals and formaldehyde.
