Carbopol 940 is a synthetic, high-molecular-weight polymer of acrylic acid, crosslinked with polyalkenyl ethers or divinyl glycol, commonly used in the pharmaceutical, cosmetic, and personal care industries.
Carbopol 940 is part of the "Carbomer" family of polymers and is recognized for its ability to form highly viscous, transparent gels at low concentrations when neutralized with a base, such as sodium hydroxide or triethanolamine.
In its raw form, Carbopol 940 appears as a white, fluffy powder that is odorless and soluble in water, where it swells dramatically to create smooth, stable gels.
Carbopol 940's unique rheological properties make it an ideal thickening agent, emulsifier, and stabilizer in a wide variety of applications.
In the pharmaceutical sector, Carbopol 940 is frequently used in topical gels, creams, and drug delivery systems, offering both controlled release and bioadhesion properties.
In cosmetics, Carbopol 940 is valued for its ability to impart a pleasant feel and texture in products like lotions, shampoos, and facial cleansers.
Carbopol 940 is highly efficient, requiring very small amounts to achieve significant viscosity, and it remains stable over a wide pH range (from 5 to 10), making it versatile for various formulations.
Additionally, Carbopol 940's compatibility with a broad range of active ingredients and its ability to suspend particles and emulsify oils further contribute to its widespread use across multiple industries.

Carbopol 940 can be used to thicken surfactant systems, and to create suspension products.
Carbopol 940 is excellent when you need to suspend heavy particles.
Viscosity actually has nothing to do with the ability of a product to suspend items such as jojoba beads or capispheres.
For instance, a shower gel as thick as jello will allow the beads to either sink or rise while a water thin product that contains Carbomer can suspend ball bearings.
This is because the Carbomer forms a Network that can trap and suspend the beads very effectively.
Carbopol 940 can also be used to create gel products very easily and cost effectively and Carbomer viscosity stands up to the incorporation of different fragrance and essential oils much better than standard surfactant thickeners.
When surfactant thickeners are used, fragrance and essential oils can get into the middle of the micellar structure of the gel formed and interfere with the structure to have a dramatic effect on surfactant system stability.
By contrast, the network created by Carbopol 940 is not influenced in this way.
