Vitamin E

By Maria Miller

INCI Name

Tocopherol (mixed tocopherols)
CAS Number: 1406-66-2 (mixed tocopherols)

Raw Material Source

Vitamin E MT-50 is derived from GMO-free refined soybean oil. The tocopherols are extracted and concentrated from the oil through a process of molecular distillation, yielding a natural blend of alpha-, beta-, gamma-, and delta-tocopherols.

Overview

Vitamin E MT-50 is a natural antioxidant complex composed of mixed tocopherols. In cosmetic formulations, it serves a dual purpose: protecting the product itself from oxidative degradation and delivering antioxidant, anti-inflammatory, and moisturizing benefits to the skin and hair. Unlike synthetic vitamin E (tocopheryl acetate), mixed tocopherols are bioactive and readily absorbed, making them highly effective in topical applications.

Cosmetic Function

  • Antioxidant: Neutralizes free radicals, protecting skin and hair from oxidative stress.
  • Preservative Booster: Extends the shelf life of oil-based formulations by preventing rancidity.
  • Anti-Inflammatory: Soothes irritation and reduces redness, particularly in sensitive skin.
  • Moisturizer: Supports the skin's lipid barrier, reducing transepidermal water loss (TEWL).
  • Photoprotective Agent: Enhances the skin's defense against UV-induced damage when used alongside sunscreen.

Mechanism of Action

Vitamin E functions primarily as a lipid-soluble antioxidant. It:

  • Scavenges free radicals: Donates hydrogen atoms to reactive oxygen species (ROS), neutralizing them before they can damage cellular membranes, proteins, and DNA.
  • Regenerates other antioxidants: Works synergistically with vitamin C, helping to restore its antioxidant capacity.
  • Modulates inflammatory pathways: Inhibits the production of pro-inflammatory cytokines, reducing skin irritation and redness.
  • Supports barrier function: Integrates into the lipid bilayer of the stratum corneum, reinforcing the skin's protective barrier.

Production & Sustainability Profile

While Vitamin E MT-50 is derived from a natural source (soybean oil), the sustainability of soybean farming is a complex issue:

  • Deforestation: Large-scale soybean cultivation, particularly in South America, has been linked to deforestation and habitat loss.
  • Monoculture farming: Intensive soy farming can deplete soil nutrients and increase reliance on synthetic fertilizers and pesticides.
  • GMO concerns: Although Vitamin E MT-50 is sourced from GMO-free soybeans, the majority of global soy production is genetically modified, raising concerns about biodiversity and ecosystem health.

More sustainable alternatives: Vitamin E can also be sourced from sunflower oil, wheat germ oil, or rice bran oil, which may have lower environmental footprints depending on farming practices. When sourcing Vitamin E, look for suppliers committed to:

  • Certified organic or regenerative agriculture
  • Transparent supply chains
  • Third-party sustainability certifications (e.g., RSPO for palm-free alternatives, Fair Trade, etc.)

Benefits for Skin

  • Antioxidant Protection: Shields skin from environmental stressors like pollution and UV radiation.
  • Anti-Aging: Reduces the appearance of fine lines and wrinkles by protecting collagen and elastin from oxidative damage.
  • Soothing & Calming: Reduces redness and irritation, making it ideal for sensitive or reactive skin.
  • Barrier Support: Strengthens the skin's lipid barrier, improving hydration and resilience.
  • Wound Healing: Accelerates recovery from minor abrasions, sunburn, or environmental stress.

Benefits for Hair

  • Scalp Health: Antioxidant properties help protect the scalp from oxidative stress, supporting a healthy environment for hair growth.
  • Shine & Smoothness: Nourishes the hair shaft, improving manageability and reducing frizz.
  • Protection from Damage: Shields hair from UV radiation and heat styling, reducing breakage and split ends.
  • Moisture Retention: Helps lock in hydration, preventing dryness and brittleness.

Applications in Natural Moxy Formulations

Vitamin E MT-50 is versatile and stable, making it suitable for a wide range of formulations:

  • Facial Oils & Serums: For antioxidant protection and anti-aging benefits, like in our Charcoal Facial Cleanser
  • Moisturizers: To support barrier function and hydration, featured in our Peptide Renewal Moisturizer
  • Sunscreens & After-Sun Products: To enhance photoprotection and soothe sun-exposed skin
  • Hair Oils: For scalp health and shine, like our Sacred Roots Hair Oil
  • Conditioner Bars: To protect and nourish hair, featured in our Amber Glow Conditioner Bar
  • Hair Growth Treatments: For scalp antioxidant support, like in our Crown Peptide Serum
  • Body Butters & Balms: To prevent oxidation and deliver skin-soothing benefits
  • Exfoliating Scrubs: For antioxidant protection during exfoliation, featured in our Peppermint Coffee Scrub

Typical Use Concentration: 0.1–1% as a preservative booster; 1–5% for skin and hair benefits.

Safety & Regulatory Notes

  • INCI Status: Approved for use in cosmetics globally (EU, US, Canada, etc.)
  • Safety Profile: Generally recognized as safe (GRAS) with minimal risk of irritation or sensitization.
  • Pregnancy & Nursing: Considered safe for topical use during pregnancy and lactation.
  • Patch Testing: Recommended for individuals with known sensitivities, though reactions are rare.
