Description

Glycols, 1,2-, C15-18 is a defined mixture of long-chain α-glycols, primarily used as a versatile intermediate and functional additive. This product offers a unique combination of hydrophilicity from the glycol group and lipophilicity from the C15-18 hydrocarbon chain, making it valuable for modifying surface properties and performance. It is particularly sought after by formulators in the lubricant, surfactant, and personal care industries for its emulsifying, coupling, and conditioning properties.

Application

• As a coupling agent and co-emulsifier in industrial and institutional cleaning formulations.
• As a viscosity modifier and lubricity additive in synthetic and semi-synthetic metalworking fluids and lubricants.
• As a skin-conditioning agent and emollient in cosmetic and personal care products like creams and lotions.
• As a intermediate for the synthesis of ester-based surfactants and specialty polymers.
• As a dispersant and processing aid in pigment concentrates and textile auxiliaries.
• As a component in specialty coatings and ink formulations to improve flow and substrate wetting.
