CID 133126848 is a chemical compound that has two main functions when used in cosmetics. Firstly, it helps to stabilize the color of the product by preventing it from fading due to exposure to light. Secondly, it controls the thickness or consistency of the product by acting as a viscosity controller. This compound can also be used as a food thickening and gelling agent in Europe, specifically as hemc with low hydroxyethyl ratio.

What is the purpose of Hydroxyethyl methyl cellulose in personal care products? It is used for its light stabilizer and viscosity-controlling characteristics. Hydroxyethyl methyl cellulose shields ingredients from damage caused by light exposure and adjusts the thickness of a product.

Names and identifiers that we found for this substance include: Hydroxyethyl methyl cellulose and "Cellulose, 2-hydroxyethyl methyl ether".

What Are Light Stabilizer Ingredients?

Hydroxyethyl methyl cellulose has light stabilizer characteristics.

Light stabilizer ingredients are commonly added to cosmetic products to protect them from light's damaging effects. These ingredients work by preventing light from breaking down the active ingredients in the cosmetic product, which can lead to the ingredients becoming less effective or even causing harm to the skin.

When a cosmetic product is exposed to light, the energy from light can cause chemical reactions to occur within the product. These reactions can break down the active ingredients, causing them to become less effective. In addition, these reactions can create new compounds that may harm the skin. Light stabilizer ingredients prevent these reactions from occurring by absorbing the energy from the light and dissipating it as heat. This process protects the active ingredients in the product and prevents the formation of harmful compounds.

Light stabilizer ingredients are essential in skincare products that contain active ingredients such as retinoids, vitamin C, and alpha hydroxy acids. These ingredients are known to be particularly sensitive to light, and their effectiveness can be significantly reduced if they are not protected.

In addition to protecting the active ingredients in the product, light stabilizer ingredients can also help maintain the product's appearance and texture. Light exposure can cause cosmetic products to change color, become cloudy, or separate. Light stabilizer ingredients prevent these changes from occurring, ensuring that the product remains stable and effective.

What Are Viscosity-Controlling Ingredients?

Hydroxyethyl methyl cellulose has viscosity-controlling characteristics.

Viscosity-controlling ingredients increase or decrease the thickness of a product. These ingredients are essential in creating the desired texture and consistency for cosmetic products such as lotions, creams, and serums.

Increasing the viscosity of a cosmetic product can provide a thicker and more substantial texture, making it easier to apply and providing better coverage. On the other hand, decreasing the viscosity can create a lighter, more fluid consistency, allowing for quicker absorption into the skin.
