General Description

Nanoshield-BHT is a nanoencapsulated form of Butylated Hydroxytoluene (BHT), designed for enhanced performance in cosmetic and personal care formulations. BHT is a lipophilic antioxidant that helps protect cosmetic products from oxidation and rancidity. The nanoshield technology improves its stability, controlled release, and compatibility in both oil-based and emulsified systems.

The encapsulation also minimizes direct skin exposure to BHT, making it more suitable for formulations targeting sensitive skin or clean-label claims.

Uses in the Cosmetic Industry

Nanoshield-BHT is used for its stabilizing and antioxidant properties in a wide range of formulations, including:

Skincare Products: Serums, creams, lotions, moisturizers

Haircare Products: Conditioners, hair oils, styling products

Color Cosmetics: Lipsticks, foundations, BB creams

Sunscreens: Prevents degradation of UV filters and oils

Fragrance Protection: Stabilizes essential oils and fragrance components

Key Functions:

  • Prevents rancidity in oils and fats
  • Extends shelf life of active ingredients
  • Enhances product stability against oxidation
  • Reduces discoloration and off-odors due to degradation


Hazards and Safety Concerns

While Nanoshield-BHT offers improved safety via encapsulation, BHT itself is a regulated synthetic antioxidant, and its use must comply with regional guidelines.

Safety Overview:
Topical Use: Generally recognized as safe at low concentrations (usually < 0.1%)

Allergy Risk: Low, but potential skin sensitivity in certain individuals

Encapsulation Benefit: Reduces direct skin contact and enhances delivery control

Regulatory Limits:
The EU Cosmetic Regulation allows BHT in rinse-off and leave-on cosmetics within safe concentration limits

Concentration Limit (EU): Max 0.1% in finished products (as a guideline; may vary)

BHT is not banned, but its use is monitored due to potential endocrine and environmental concerns

Environmental Consideration:
May raise concerns in eco-conscious formulations due to its synthetic origin and potential aquatic toxicity in high concentrations

1. CAS Number: 128-37-0 (Butylated Hydroxytoluene – BHT)
Other CAS numbers may apply depending on the encapsulating or carrier materials.


2. INCI NameL: Butylated Hydroxytoluene (and) [Encapsulation Matrix, e.g., Silica, Lecithin, or Liposome Carrier]
INCI may vary slightly depending on the nanoencapsulation system used.


3. Composition; Active Ingredient: Butylated Hydroxytoluene (BHT)

Encapsulation System: Typically lipid-based nanocarriers, polymers, or silica shells

Carrier Medium: Water, glycerin, ethanol, or caprylic/capric triglycerides depending on product type


4. Purity Grade: Cosmetic Grade / Pharmaceutical Grade BHT

Encapsulated BHT content typically: 0.1% – 1.0% (w/w in dispersion)

Compliant with GMP and ISO 22716 standards for cosmetic ingredients


5. Appearance: Milky-white to translucent dispersion (in liquid form)

Can also be found as a fine white powder in dry encapsulated form

No visible particles; smooth texture


6. Solubility: BHT: Insoluble in water, soluble in oils and alcohols

Nanoshield-BHT (encapsulated form): Dispersible in both oil- and water-based systems depending on formulation


7. Preservation: Self-preserving in many encapsulated forms

Some versions may contain Phenoxyethanol, Ethylhexylglycerin, or Sodium Benzoate for added microbial protection

Preservative-free options may be available on request


8. Storage: Store in a cool, dry, and dark place

Avoid exposure to heat, humidity, or direct sunlight

Storage Temperature: 5°C – 25°C

Shelf Life: 12 to 24 months (unopened, under recommended conditions)


9. Raw Material Sources: BHT: Synthetic, derived from petroleum-based feedstocks

Carrier Matrix: May be natural (e.g., lecithin, phospholipids) or synthetic (e.g., silica or polymeric shells)

10. Manufacture: Produced through nanoencapsulation technology:

  • High-shear homogenization
  • Liposomal or polymer-based encapsulation
  • Ensures controlled release, protection from oxidation, and reduced skin exposure

    Manufactured under ISO/GMP-compliant processes for personal care raw materials


11. Animal Testing: Typically not tested on animals

Cruelty-free status depends on supplier policy and third-party certifications (e.g., Leaping Bunny, PETA)


12. GMO Status: Non-GMO – No genetically modified organisms used in the production of BHT or encapsulation systems


13. Vegan Status: Generally considered vegan – does not contain animal-derived materials

Confirm with supplier if using lecithin-based carriers (some may be animal-derived)

14. Proposition 65 (California): BHT is listed under California Proposition 65 as a chemical known to cause cancer (based on certain toxicology data)

Products using Nanoshield-BHT may require appropriate labeling in California

15. Warnings & Precautions: For external use only:

  • Avoid inhalation of powder form
  • Use within approved concentration limits (typically ≤ 0.1% in leave-on cosmetics)
  • Avoid use in formulations marketed as “all-natural” or “synthetic-free”
  • Regulatory compliance must be reviewed for EU, USA, Canada, and Asia-Pacific regions individually

FAQ (Frequently Asked Questions)

Nanoshield-BHT is a nanoencapsulated antioxidant ingredient used in cosmetic and personal care products to protect formulations from oxidation and extend shelf life. It contains Butylated Hydroxytoluene (BHT), stabilized within a controlled delivery system to reduce direct skin exposure and improve performance.

CAS Number: 128-37-0 (for BHT)
INCI Name: Butylated Hydroxytoluene (and) [Encapsulation matrix, such as Silica or Lecithin depending on formulation]

Nanoshield-BHT provides several advantages:
Prevents oxidation of oils, fats, and sensitive actives
Extends product shelf life and fragrance stability
Minimizes off-odors and discoloration in formulations
Nanoencapsulation ensures controlled release and reduced irritation risk
Suitable for anti-aging, haircare, suncare, and premium skincare applications

Yes, when used within recommended limits (typically ≤0.1%), Nanoshield-BHT is considered safe for cosmetic use. Encapsulation helps reduce direct contact between BHT and the skin, enhancing its tolerability in leave-on products.

Nanoshield-BHT can be used in:
Face creams and serums
Hair oils and conditioners
Lipsticks and balms
Sunscreens and anti-pollution skincare
Fragrance-containing products

Nanoshield-BHT can meet certain standards depending on its encapsulating material:
Cruelty-free (not tested on animals)
Non-GMO
May be vegan, but verify if encapsulation includes lecithin (plant- or animal-derived)
Not suitable for 100% natural or “free-from synthetics” claims due to synthetic BHT content

Yes, but it must be used within approved limits:
EU Regulation (EC) No 1223/2009 permits BHT at safe concentrations
Listed under California Proposition 65 for potential carcinogenicity – labeling may be required in California
Always check local regulatory compliance for leave-on vs rinse-off use

While BHT itself is an antioxidant, Nanoshield-BHT may contain additional preservatives (e.g., Phenoxyethanol or Sodium Benzoate) depending on the formulation. Some versions are available preservative-free upon request.

Store Nanoshield-BHT in a cool, dry place, away from sunlight and moisture.
Recommended temperature: 5°C to 25°C
Shelf life: 12–24 months (in original sealed packaging)

Nanoshield-BHT is efficient in small concentrations, but BHT is synthetic and may raise environmental concerns in large-scale use. Brands aiming for eco-certification or biodegradable claims may prefer to limit its use or explore natural antioxidant alternatives.
