Steareth-7

1. Definition Steareth-7:

Steareth-7 is a polyethylene glycol ether of stearyl alcohol, which is commonly used as an emulsifier and surfactant in cosmetics. It helps to stabilize and blend oil and water-based ingredients in formulations, allowing for a smooth and uniform texture.

2. Use:

Steareth-7 is often included in skincare products such as creams, lotions, and cleansers to improve the consistency and spreadability of the product. It also helps to enhance the overall performance of the formulation by ensuring that the active ingredients are evenly distributed and absorbed by the skin.

3. Usage Steareth-7:

When using products containing Steareth-7, it is important to follow the manufacturer's instructions and guidelines for application. It is generally considered safe for use in cosmetics, but individuals with sensitive skin may want to perform a patch test before using a product with this ingredient to check for any potential irritation or allergic reactions.

Precautions: While Steareth-7 is generally considered safe for use in cosmetics, some individuals may experience skin irritation or allergic reactions. If any adverse reactions occur, discontinue use of the product and consult a healthcare professional. It is also important to avoid getting the product in contact with eyes or mucous membranes.
