Isomerized Linoleic Acid

Product Description

As a specialized supplier of innovative cosmetic raw materials, we provide premium Isomerized Linoleic Acid sourced through direct factory supply to ensure the highest isomeric purity and consistent performance for sophisticated formulators. This functional lipid derivative serves as a critical signaling molecule in the epidermis, scientifically recognized for its ability to modulate ceramide synthesis and fortify the impaired skin barrier. Through advanced lipid-carrier technologies, this unsaturated fatty acid can be formulated to remain stable in aqueous solution, ensuring enhanced transdermal delivery and offering an evidence-based solution for brands developing advanced recovery creams, post-procedure care, and sensitive-skin maintenance regimens.

Key Benefits & Applications

Our premium grade Isomerized Linoleic Acid delivers comprehensive structural repair and soothing efficacy for compromised skin barrier systems:

• Epidermal Barrier Repair: Actively promotes the synthesis of crucial stratum corneum lipids, strengthening the skin's natural moisture-locking matrix and significantly preventing transepidermal water loss (TEWL).
• Anti-Inflammatory Modulation: Reduces the up-regulation of pro-inflammatory cytokines at the cellular level, making it an excellent choice for managing reactive, irritated, or post-procedure skin conditions.
• Sebum Homeostasis & Regulation: Assists in stabilizing follicular lipid composition, contributing to a more balanced, clear, and refined skin texture without compromising baseline barrier integrity.
• Targeted Applications: Recommended for inclusion in barrier-repair recovery creams, sensitive-skin facial serums, post-dermatological procedure treatments, and high-performance night repair formulations.

Formulation Guidelines

• Solubility: Highly lipophilic; effectively disperses in the oil phase of emulsions. Ensure high-shear mixing during the emulsification stage for optimal droplet distribution.
• Thermal Stability: Heat stable up to 75°C. For maximum chemical integrity in sensitive skin formulas, it is highly recommended to incorporate during the final cooling phase at temperatures below 50°C.
• pH Range: Maintains optimal chemical stability across a broad physiological pH range of 4.5 to 7.5.
• Oxidation Control: As an unsaturated fatty acid derivative, it is highly prone to rancidity. Always co-formulate with high-potency lipophilic antioxidants such as Tocopherol or Ascorbyl Palmitate, and utilize opaque, airless packaging.
• Synergy: Combine with Bisabolol to dramatically accelerate stratum corneum lipid replenishment while enhancing the overall calming and anti-inflammatory efficacy in sensitive skin care formulations.
