Esterquat (EQ)

Esterquat (EQ) is a class of quaternary ammonium compounds derived from fatty acids and used primarily as a biodegradable fabric softener. Esterquats are considered more environmentally friendly than traditional fabric softeners due to their ability to break down more easily in nature. They are typically produced by the reaction of fatty acids with triethanolamine, followed by quaternization, which gives them their conditioning properties.

Most Common Applications of Esterquat (EQ):

Fabric Softeners: Esterquat is widely used in liquid fabric softeners and dryer sheets. It helps to soften fabrics, reduce static cling, and make clothes feel smoother to the touch after washing.

Laundry Detergents: In laundry formulations, esterquat is often combined with detergents to provide dual benefits of cleaning and softening, offering convenience for consumers looking for both in one product.

Hair Conditioners: Due to its conditioning properties, esterquat is used in hair care products, particularly in conditioners and leave-in treatments, to make hair feel softer, smoother, and easier to manage without leaving heavy residue.

Household and Industrial Cleaning Products: Esterquat can be found in certain cleaning formulations for both household and industrial use, where it provides a conditioning effect on surfaces, leaving them with a soft and smooth finish.

Personal Care Products: Esterquat is occasionally used in creams and lotions to enhance the spreadability and smoothness of the product on the skin.

Esterquats are appreciated for their high performance and biodegradability, making them a more sustainable choice in the fabric care and personal care industries. Their ability to soften and condition without leaving a greasy residue makes them popular across a range of applications.
