Latex Testing

Verify Compliance and Substantiate Label Claims

Furniture Business Challenges

In a global marketplace where product safety is a critical component to success, the presence of Natural Rubber Latex can be a key risk factor for a wide variety of industries including medical device, health and beauty, pharmaceuticals, textiles, office products, and toys. Products containing Natural Rubber Latex that come into contact with the skin can cause a severe life threatening allergic reaction, presenting potential liability for the manufacturer and retailer.

According to the US Centers for Disease Control and Prevention, up to 6% of the general population has a sensitivity or allergy to the proteins in Natural Rubber Latex. There has also been an increase in sensitivity to the accelerators used in Natural Rubber Latex and Synthetic Latex manufacturing. It is not only important to understand the content of your products, but also the manufacturing environment and critical suppliers from raw material to finished product.

Validating label claims can be challenging and confusing. Some global governmental agencies have established guidelines for product labeling to ensure that consumers are not misled by claims regarding latex

Testing Capabilities

ASTM D5712 Modified Lowry / Total Protein: Determines the amount of total aqueous extractable protein associated with natural rubber, latex, and elastomeric products.*

ASTM D6214 Powder Content: Determines the average powder or filter-retained mass found on a sample of medical gloves.

ASTM D6499 Inhibition ELISA: Determines the amount of antigenic protein in natural rubber and its products using rabbit antisera specific for natural rubber latex (NRL) proteins.*

ASTM D7247 Allergenic ELISA: Determines the amount of four principal allergenic proteins (Hev b 1, 3, 5 and 6.02) in natural rubber and its products derived from latex.

ASTM D7558 Chemical Sensitivity: Determines the amount of total extractable accelerators in natural rubber latex (NRL) and nitrile gloves.

ASTM Guayule ELISA ASTM WG 25943: Measures the levels of extractable Guayule proteins from commercial products. This method is still in validation steps with the ASTM.

SDS-PAGE – SDS Poly Acrylamide Gel Electrophoresis: Used to separate proteins from a sample by mixing with SDS and electrically drawing proteins through a polyacrylamide matrix.

Western Blot – Gel to Membrane Transfer: The proteins from a SDS-PAGE are transferred to a nitrocellulose membrane where the membrane is blocked and proteins are stained with antibodies specific to target protein.
