Application: • Synthesis of lactose-based surfactants: Research by Enayati, Gong, and Abbaspourrad demonstrated the use of d-Lactose monohydrate in the synthesis of lactose lauryl ester, employing aluminosilicate zeolite as a catalyst. This study presents a method for producing non-ionic surfactants, highlighting d-Lactose monohydrate′s role in industrial and pharmaceutical applications (Enayati et al., 2019 ).

New Tariffs & Effects on Pricing

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
