Quick Specs:

  • INCI Name: Limnanthes Alba (Meadowfoam) Seed Oil

  • CAS Number: 153065-40-8

  • Appearance: Clear, light yellow to golden lipid liquid

  • Odor: Faint, characteristic earthy/seed odor (practically odorless in fully refined grades)

  • Recommended pH Range: 3.0 – 8.0 (Formulation pH; lipid is inherently anhydrous)

Executive Summary:  SKIN001 supplies premium-grade Limnanthes Alba (Meadowfoam) Seed Oil, a highly stable seed oil distinguished by an extraordinary fatty acid profile composed of over 95% long-chain fatty acids. Dominated by eicosenoic acid (C20:1) and docosadienoic acid (C22:2), this distinct structural geometry confers remarkable thermal resilience and makes it an elite oxidation-resistant lipid. Its primary mechanism of action centers on intercellular matrix replenishment and surface occlusion; the long-chain triglycerides form a non-comedogenic, biomimetic seal over the stratum corneum, effectively mitigating transepidermal water loss (TEWL) while imparting a substantive, velvety cushion to topical emulsions.

For R&D formulators, Meadowfoam Seed Oil represents a critical functional lipid that not only provides elegant tactile properties but also significantly extends the shelf-life of formulations by stabilizing less stable carrier oils when blended. Unlike conventional polyunsaturated botanical extracts, it exhibits extraordinary oxidative resilience without the need for heavy antioxidant systems like BHT or high-dose tocopherols. Its unique sensory profile—providing excellent slip, rich skin feel without tackiness, and prolonged spreadability—makes it a superior choice for formulating complex skin barrier repair serums, substantive eye creams, and dermatological bases where prolonged hydration is paramount.

Formulation Guidelines:

  • Recommended Usage Rate: 1.0% – 15.0% in standard O/W or W/O topical emulsions; up to 100.0% in anhydrous systems (lipid blends, lip care, balms).

  • Solubility: Fully soluble in cosmetic esters, vegetable oils, squalane, and non-polar solvents. Insoluble in water.

  • Phase Integration: Add directly to the heated oil phase. Exceptionally heat tolerant; withstands temperatures up to 85°C – 90°C during the emulsification process without lipid degradation or the generation of off-odors. Compatible with high-shear homogenization and standard non-ionic, anionic, and cationic emulsifier networks.

Primary Applications:

  • Biomimetic skin barrier repair serums and intensive lipid concentrates.

  • Advanced eye creams requiring substantive, non-migrating hydration.

  • High-stability topical emulsions (O/W and W/O) and rich night creams.

  • Anhydrous color cosmetics (lipsticks, lip balms), serving as an excellent binder, pigment wetter, and longevity enhancer.

  • Massage oils and body butters requiring prolonged slip and shelf-life extension.
