Evening Primrose Oil (Responsibly Grown)

• Dilute with lighter oils such as Jojoba Oil or Camelia Seed Oil to help Cold Pressed Evening Primrose Oil absorb more quickly.
• A perfect superstar ingredient to add to chaotic, confused, and sensitive skincare lines.
• Can be included as an ingredient in skincare formulations or used on the skin at 100%.

Incorporate into the oil phase of emulsions. No heating required; add at cool-down if heat-sensitive antioxidants are present. Typical use level 1-20%.

• Solubility: Soluble in: oils (vegetable oils, fixed oils, cosmetic esters, light petroleum/mineral oil).
• Dispersible in: N/A.
• Processing Temperature: Add at: room temperature.
• Heat tolerance: Heat-sensitive — prefer cool-down or room temp addition.
• Avoid: high heat (>158°F/70°C).
• Melting Point / Form: Liquid at room temperature.
• Recommended Phase: Oil phase (heated or cool-down)
• Recommended pH: N/A — anhydrous

Option 1: Facial Serums & Facial Oils

Use at 1–20% in anhydrous facial serums and oil blends. Rich in linoleic acid and GLA; add at room temperature or cool down and pair with an antioxidant to support stability.

Option 2: Emulsified Face & Body Creams

Add at 1–10% to the oil phase or cool-down phase of creams and lotions. Heat-sensitive, so avoid temperatures above 158°F (70°C) to help preserve the fatty acids.

Option 3: Targeted Balms & Concentrates

Use at 2–20% in balms and oil concentrates for the face and dry-feeling areas. Store light-protected and blend with more stable oils to support shelf life.

Option 4: To Add to a Finished Base

To incorporate evening primrose oil into a finished cosmetic base, stir it directly into the product at room temperature, since it is liquid and blends easily. Add it at 1–10% of the total weight while mixing gently and continuously until homogeneous. Because it is a heat-sensitive functional ingredient rich in fatty acids, keep the base below 40°C (104°F) and add it last, then check texture and consistency before repackaging. Skin should feel softer and well conditioned after use.
