Description

Isostearoyl Hydrolyzed Collagen is a modified protein derivative where hydrolyzed collagen is acylated with isostearic acid, resulting in a substantive conditioning agent with enhanced lipid compatibility. This modification is crucial for improving the substantivity, emolliency, and film-forming properties of collagen in cosmetic and personal care formulations. It is primarily needed by manufacturers in the cosmetics, skincare, and haircare industries seeking advanced bio-functional ingredients.

Application

• Hair Care Products: Acts as a conditioning agent and film-former in shampoos, conditioners, and hair masks to improve manageability, shine, and reduce static.
• Skin Care Formulations: Used in creams, lotions, and serums as a moisturizing and smoothing agent to enhance skin feel and provide a protective barrier.
• Color Cosmetics: Incorporated into foundations, lipsticks, and mascaras to improve texture, adhesion, and wear comfort.
• Personal Cleansers: Adds conditioning benefits to body washes and syndet bars, preventing moisture stripping from the skin.
• Anti-aging Products: Valued for its potential to improve skin elasticity and reduce the appearance of fine lines as a functional bioactive.
• Pharmaceutical Topicals: May be used in ointments and creams as a soothing and protective excipient.
