Palm and/or canola oil” denotes either palm oil, canola (low-erucic rapeseed) oil, or a blend of the two in variable ratios. The selection or blending tunes oxidative stability, melting profile, texture, and nutritional lipid profile for food and cosmetic applications.

Calories (energy value)
≈ 884 kcal per 100 g (typical of 100% lipid oils).

Fatty-acid composition (indicative ranges)
Actual values vary with cultivar, geography, season, refining, and fractionation.

  • Palm oil (unfractionated)

    • SFA ~45–50% (Palmitic ~40–47%, Stearic ~4–6%)

    • MUFA ~37–45% (Oleic ~36–43%)

    • PUFA ~8–12% (Linoleic ~8–11%, α-Linolenic <1%)

    • Fractionation yields palm olein (more fluid, PUFA↑) and palm stearin (more solid, SFA↑)

  • Canola oil (low-erucic rapeseed)

    • SFA ~6–8%

    • MUFA ~58–66% (Oleic ~58–65%)

    • PUFA ~25–32% (Linoleic ~18–24%, α-Linolenic ~8–12%**)

    • Erucic acid: trace in canola spec (typically <2%)

Unsaponifiables and micronutrients

  • Tocopherols/tocotrienols: palm rich in tocotrienols; canola rich in α/γ-tocopherol

  • Phytosterols: present in both (β-sitosterol predominant)

  • Carotenoids: high in red/orange unrefined palm (β-carotene); greatly reduced after refining

Physicochemical properties (refined grades)

  • Appearance: palm semi-solid pale yellow at room temperature (unfractionated); canola liquid, light yellow

  • Odor/flavor: neutral (refined/deodorized)

  • Melting behavior: palm ~24–27 °C (stearin >40 °C; olein remains liquid); canola liquid at room temperature

  • Smoke point (approx., refined): palm olein ~230–235 °C; canola ~220–230 °C

  • Iodine value: palm ~50–55; canola ~110–126

  • Saponification value: palm ~196–205 mg KOH/g; canola ~182–193 mg KOH/g

Functional profile (cosmetics)

  • Emolliency/conditioning: soft slip; canola gives a lighter skin feel, palm (esp. stearin) adds body/structure.

  • Oxidative stability: palm > canola (higher SFA, tocotrienols). Blends strike a balance of stability and spreadability.

  • Structuring: palm stearin increases hardness and pay-off in sticks/balms; canola fluidizes and improves spread.

  • Comedogenicity (indicative): palm ~3–4; canola ~1–2 (skin- and dose-dependent).

Applications

  • Cosmetic: body creams, lip balms, sticks/ointments (palm/fractions for structure; canola for a lighter oil phase); traditional soapmaking (palm/stearin add hardness and creamy lather).

  • Food: deep frying, snacks, margarines/shortenings (with stearin), baking; canola for dressings, mayonnaises, and “heart-friendly” cold uses.

Safety and regulatory notes

  • Allergens: refined oils carry minimal protein residues; typical allergenicity is very low.

  • INCI labeling: “Elaeis Guineensis Oil”; “Canola Oil” / “Brassica Napus (or Campestris) Seed Oil” depending on market.

  • EU Cosmetics (Reg. 1223/2009): no specific restrictions for refined vegetable oils; use under GMP.

  • Food: must meet purity standards; canola may be GMO depending on origin (declare where required).

Sustainability and supply chain

  • Palm oil: concerns include deforestation and biodiversity loss → prefer RSPO-certified (or equivalent) and traceable supply.

  • Canola: variable footprint by region/cultivation; consider non-GMO/organic as required; good crop rotation and high yields.

  • Packaging/storage: light/oxygen-barrier containers; use tocopherols as natural antioxidants where appropriate.

Stability and storage

  • Oxidation: canola (PUFA↑) is more prone; palm is more stable. Blending reduces trade-offs.

  • Shelf life: typically 12–24 months when stored cool, dark, and dry with limited oxygen exposure.

Formulation tips (cosmetics)

  • For sticks/balms: combine palm stearin with waxes (beeswax/carnauba/candelilla) and light oils (canola, esters) to balance hardness, melting point, and pay-off.

  • For O/W emulsions: canola enhances light sensory; a portion of palm olein adds body without excessive occlusion.

  • Antioxidation: add vitamin E (tocopherol 0.05–0.2%) and minimize heat/light/air exposure.

Nutritional considerations (food)

  • Palm: higher SFA (palmitic) → excellent thermal stability and structuring in bakery.

  • Canola: high MUFA and ALA (ω-3) ~8–12% → more favorable lipid profile; ideal for cold use and dressings.

  • The blend allows tailoring frying stability (palm) and nutritional profile/neutral flavor (canola).
