What is Bisphenol?

Bisphenol is a synthetic organic compund containing 2 phenol groups (two hydroxyl phenyl groups) and it is used mainly for making plastics and resin.

Types of Bisphenol

Receives much attention due to their advantages of filling property, dispersibility, and bleachability.

Well suited for all color shades and result in leathers with a better lightfastness, compared to leathers retanned with vegetable tannins.

Generally prepared through condensation, sulfonation, and other reactions by using phenol or naphthalane, formaldehyde, and concentrated sulfuric acid as raw materials.

Phenolic monomers such as phenol.

Phenol sulfonic acid

bisphenol S (dihydroxy diphenyl sulphone)

bisphenol F

These compounds are used as either starting materials or intermediate molecules formed during the manufacturing process.

In general, aromatic syntans are condensates of phenolsulfonic acid and/or phenol and/or dihydroxydiphenylsulfone (DHDPS or Bisphenol S) with formaldehyde where urea is optionally used.

Bisphenol S (dihydroxyl diphenyl sulphone) is used as raw materials for the manufacturing of sulphone syntans.

Depending upon the efficiency of the consideration process, a certain amount of phenolic monomers are left unreacted during the manufacturing process. This unreacted phenol may react with formaldehyde, resulting in the formation of bispenol F.

In the leather industry, these phenol/sulphone syntans are primarily used for pre-tanning, tanning, retanning and dyeing.

These unreacted phenolic monomers such as phenol, phenolsulfonic acid and bisphenol S/F that are present in the syntans, will be transferred to the leather during the (re)-tanning processes.

Bisphenol and its derivatives are known endocrine descriptors that are harmful to both human health and the environment, as well as causing reproductive toxicity.

In 2020, the European Chemicals Agency (ECHA) and the EU Member States screened data on a large group of Bisphenols such as BPA, BPS, BPF, BPAF and their derivatives and recommended the restriction of more than 30 bisphenols.

In 2022, The European Chemicals Agency (ECHA) pre-published a Restriction draft on BPA & BosC; including BPS/ BPF based on the Annex XV Restriction report prepared by Germany, which proposes a concentration limit of 500 ppm for leather articles and mixtures used for the tanning of leather for a 5-year period.

On January 17, 2023, the European Chemicals Agency (ECHA) added nine substances to the Candidate List of substances of very high concern (SVHC) under the REACH Regulation, including 4,4’-sulphonyl diphenol (Bisphenol S) and Melamine.

The restriction proposal and the new addition of Bisphenol S in SVHC, result in high demand for Bisphenol free and low bisphenol leather and chemicals in the global leather market.

GG Organics is proud to be at the forefront of the leather industry for over decades, providing cutting-edge technology, development and technical services. Our commitment to the customer and the environment is paramount, and with the introduction of new regulations on Bisphenols, we are proud to be the first Indian company to present solutions with the launch of our syntan range.

Our new syntans are designed to comply with the upcoming bisphenol limits and we are continually investing in research to ensure our customers remain in compliance with future regulations. With our expertise and unparalleled positioning, GG Organics is your ideal partner to help you stay ahead of the game and remain compliant with ever-changing regulations.

The leather industry is facing a daunting challenge in meeting the environmental standards due to the use of high impact chemicals in the leather processing. Formaldehyde, a known carcinogen, is used in the production of syntans while bisphenols and Bisphenol of Similar Concern (BoSC- Bisphenol A, B. AF, Fand St. a family of synthetic organic chemicals, are used in the production of polymers, plastics, and retanning agents, which are known endocrine disruptors, making it essential to find a safe and sustainable solution for the tanners.

To address this issue, GG Organics his developed no formaldehyde syntars from special derivatives and low bisphenol syntansmade using covet methodologies and its monomer chemistry, aiding tanners in producing high-quality leather and giving immense benefits to people and nature

GG Organics is proud to launch its Benita brand-a collection of specially formulated, superior quality and safe chemicals. With Benitan, you can trust you're using high quality products that are sure to deliver remarkable results.

The GG Organics BENITAN range is the ideal choice for leather producers looking to create premium quality leathers without the risk of formaldehyde and bisphenols. Our BENITAN products are safe retanning chemicals that give tanners an edge in the market by creating risk-free leathers

The Benitan products are most suitable for the production of top-quality leather such as Shoe upper, goods, garments and upholstery

Low Bisphenol Retanning Agents: Benitan B01, Benitan B02, Benitan B04, Benitan 805 and Benitan 808-Benitan 814

Safe products with No Formaldehyde: Benitan F03, Benitan F06 and Benitan F07

GG Organics has developed phenol-based retanning agents with desired limits of bisphenol content by using an innovative process, technology and monomer chemistry.

BPA, BPB and BPAF are not present in any of our retanning agents.

The real challenge is matching the properties of conventional syntans. We did this with our new range.

GG Organics’ cutting-edge laboratory has been upgraded with advanced LC-MS testing equipment for identifying the concentration of bisphenol in retanning agents and leather. This would ensure an efficient delivery mechanism in the frontier areas of the leather industry.

All of our low bisphenol products are evaluated with LC-MS technology, and the results were below the limit proposed by BAuA and the major customers.

In the leather industry, these phenol/sulphone syntans are primarily used for pre-tanning, tanning, retanning, and dyeing.
