Description

Dimethylsilanol Hyaluronate is a unique organosilicon derivative of hyaluronic acid, combining the hydrating properties of a glycosaminoglycan with the film-forming and skin-adhesive characteristics of silicone. This compound matters for its ability to deliver enhanced, long-lasting moisturization and create a smooth, protective barrier on the skin's surface. It is primarily needed by formulators in the cosmetic and personal care industries for advanced skincare, anti-aging, and haircare products.

Application

• Anti-Aging & Wrinkle-Reduction Serums and Creams: Acts as a high-performance moisturizing and film-forming agent to improve skin elasticity and reduce the appearance of fine lines.
• Advanced Hydrating Moisturizers and Lotions: Provides intense, long-lasting hydration by forming a breathable occlusive layer that prevents transepidermal water loss (TEWL).
• Leave-In Conditioners and Hair Repair Treatments: Imparts shine, smoothness, and manageability to hair while providing conditioning benefits without heavy buildup.
• Makeup Primers and Foundations: Creates a smooth, uniform canvas for makeup application, enhancing wear time and product spreadability.
• Post-Procedure Skincare: Used in formulations designed to soothe and hydrate skin after cosmetic procedures like microneedling or laser treatments.
• Sun Care Products: Incorporated into sunscreens and after-sun lotions for its moisturizing and skin-conditioning properties.
