product details

Product Description

Carbomer 940 is a synthetic polymer derived from acrylic acid. It is part of a larger family of carbomers, which are widely used in cosmetic and personal care formulations. Carbomer 940 is known for its ability to thicken and stabilize emulsions, making it a popular choice in various products. It typically appears as a white, fluffy powder and is soluble in water, forming a gel-like consistency when hydrated.

Polyvinyl carboxy polymer crosslinked with ethers of pentaerythritol. Used as a viscosity enhancer or gelling agent primarily in systems where clarity or viscosity is required. Viscosity: 45,000-70,000 cps (0.5% solution).

Benefits

Thickening Agent

Carbomer 940 effectively increases the viscosity of formulations, allowing for a desirable texture in creams, gels, and lotions.

Stabilizer

It helps stabilize emulsions, preventing the separation of oil and water phases in cosmetic products.

Improved Texture

Provides a smooth, silky feel to products, enhancing the overall sensory experience for users.

Use

Typical use level 0.1-0.5% depending on the type of formulation desired viscosity. Carbomer must be thoroughly mixed and hydrated. Increasing the pH to >6.0, gives a gel structure. Neutralization can be carried out with inorganic bases such as NaOH or KOH or triethanolamine (TEA). For external use only.
