Here are some key details about Dimethicone 350:
1. Composition and Form
Dimethicone 350 refers to a specific viscosity grade of dimethicone, indicating its consistency and thickness. The number "350" refers to the viscosity in centistokes (cSt), a measure of how thick or fluid the compound is. Dimethicone 350 is a medium-viscosity silicone fluid, meaning it is not too thick or too thin.
It is typically in liquid form and can be colorless and odorless.
2. Common Uses
Skin Care: Dimethicone 350 forms a smooth, silky layer over the skin, which helps to lock in moisture. It can also smooth the skin's appearance by filling in fine lines or imperfections.
Hair Care: It provides a sleek finish to the hair, making it appear shiny and reducing frizz by coating individual strands. Dimethicone 350 is used in hair serums, shampoos, conditioners, and leave-in treatments.
Makeup: In foundations, primers, and other makeup products, it helps to create a smooth, even base and can improve the wear time of cosmetics.
Other Uses: It is also used in antiperspirants, sunscreens, and other formulations where a smooth texture, spreadability, and moisture retention are important.
3. Benefits
Smooth Application: Dimethicone 350 is valued for its ability to create a non-greasy, smooth texture that is easy to apply and leaves a soft feel on the skin or hair.
Water Resistance: It is water-resistant, which is why it's often included in formulations designed to last longer, like sunscreens or long-wearing makeup.
Moisture Retention: In skincare, it helps to prevent water loss by forming a barrier on the skin, which keeps it hydrated.
Frizz Control: In hair care, it helps to control frizz and flyaways by smoothing the cuticle layer of the hair.
4. Safety and Side Effects
Dimethicone 350 is generally considered safe for use in cosmetics and personal care products. It is non-comedogenic, meaning it is unlikely to clog pores, and hypoallergenic for most people.
Some individuals with sensitive skin may experience irritation, but this is rare.
It does not penetrate the skin deeply but works on the surface, forming a protective layer.
In summary, Dimethicone 350 is a versatile and effective ingredient widely used in the cosmetic industry for its ability to enhance product texture, improve skin and hair appearance, and provide moisture retention.
