- August, 2010, Oregon-OSHA reported analytical results detected the keratin-based hair smoothing product solution contained 4.85% formaldehyde to OHSU CROET.
- September, 2010, according to OHSU CROET, they received a second sample of the same keratin-based hair smoothing product and forwarded it to Oregon-OSHA for analytical testing. Oregon-OSHA's report indicated this bottle was also labeled “formaldehyde-free.” Oregon-OSHA reported analytical results, after using 4 separate test methods, revealed the sample contained between 6.3% - 10.6% formaldehyde.
- October, 2010, Oregon-OSHA reports analytical findings to news media.
- Oregon-OSHA develops Local Emphasis Program (LEP) [24 KB PDF, 4 pages] that addresses potential hazards of occupational formaldehyde exposures among workers using hair smoothing/straightening products and product MSDS accuracy.
- October 7, 2010, Health Canada releases a report saying it measured the product and found it contained 12% formaldehyde, which is 60 times their permissible limit for cosmetics. In response, the Brazilian Blowout company has had a class action lawsuit filed against them in Canada by citizens.
- October 8, 2010, Attempting to answer questions about whether formaldehyde exists in the samples, Oregon-OSHA releases to the press a statement [25 KB PDF, 1 page] informing that methylene glycol becomes formaldehyde gas.

- October 29, 2010, Oregon-OSHA issues a press release [36 KB PDF, 2 pages] and a Hazard Alert [495 KB PDF, 2 pages] on keratin-based smoothing products and their final report [210 KB PDF, 34 pages] on the product, concluding:
- "Oregon OSHA and CROET have concluded that there are meaningful risks to salon workers when they are confronted with these hair smoothing products. Effective control of those risks depends upon accurate information regarding the potential hazards and the control measures available, which in turn begins with an accurate understanding of the ingredients and the potential harm they may cause. In conjunction with this report, Oregon OSHA is advising Oregon salons and stylists that hair smoothing treatments – particularly those generally referred to as “Keratin-based treatments” – should generally be treated as formaldehyde-containing products and the requirements of the OSHA Formaldehyde Standard must be followed when there are employees under the Oregon
- Safe Employment Act (OSEA). Further, employers should be advised that any product that contains “methylene glycol” will continue to be treated as a formaldehyde-containing product under the OSEA."
