Diisopropyl Dimer Dilinoleate

Product Description

Our high-purity Diisopropyl Dimer Dilinoleate is manufactured under ISO-aligned controls with batch COA traceability, supplying cosmetic formulators direct factory pricing and flexible kilogram-to-tonne bulk volumes for oil-phase and emulsion systems.

This dimerized linoleic isopropyl ester forms a lightweight lipophilic film that replenishes stratum corneum lipids, reduces transepidermal water loss, and delivers silky, non-greasy spreadability—mechanisms central to barrier-repair creams, hair conditioners, and luxe emollient serums.

Unlike isopropyl myristate or heavy mineral oils, this CosIng-listed dimer dilinoleate suits clean-feel moisturizing portfolios where formulators want GC-verified assay, low tack, and direct factory supply.

Key Benefits & Applications

Diisopropyl Dimer Dilinoleate supports emollient, barrier-comfort, and moisture-retention claims through lipophilic dimer ester activity suited to cream and hair-care formulators.

• Lipid Replenishment: Dimer dilinoleate ester restores lipophilic comfort in dry-skin creams and lipid-depleted barrier repair lines.
• Skin Barrier Repair: Lightweight occlusive support helps reinforce stratum corneum barrier function in sensitive-skin emulsions.
• TEWL Control: Reduces transepidermal water loss through silky lipid film formation in moisturizers and balms.
• Deep Hydration: Locks aqueous moisture within emulsion matrices for sustained hydration in day and night care.
• Long-Lasting Moisturizing: Delivers durable emollient cushion and after-feel in luxe body and facial moisturizers.
• Lightweight Film Formation: Deposits non-tacky protective film in hair conditioners and leave-in treatment oils.

Formulation Guidelines

Incorporate diisopropyl dimer dilinoleate in the oil or silicone phase; confirm acid value and sensory profile before scale-up.

• Recommended use level: 1–10% w/w in facial emulsions; 3–20% in body and hair care (Typical).
• Optimal formula pH: Compatible pH 4–8 when added to oil phase before emulsification (Typical).
• Processing: Add to oil phase at 25–70°C; pre-blend with other esters for uniform sensorial.
• Compatibility: Miscible with silicones, squalane, and ceramides; suitable for W/O and O/W emulsions.
• Caution: Excessive levels may increase slip or reduce absorption—balance with lighter esters in oily-skin formulas.
• Synergy: Layer Ceramide NP beneath diisopropyl dimer dilinoleate in barrier-repair creams at 0.5–1% for stacked lipid support.
