General Description

Nanosun-BS is a specialized cosmetic-grade nano zinc oxide dispersion commonly used as a UV filter in sunscreen and skin protection formulations. It typically contains nano-sized zinc oxide particles (ZnO) suspended in a medium (e.g., butylene glycol, water, or caprylic/capric triglycerides), ensuring even distribution and minimal white cast on the skin.

The "BS" suffix may refer to the base system or dispersing medium, depending on the manufacturer. It is often designed to be non-whitening, photostable, and suitable for broad-spectrum UVA/UVB protection.

INCI Example: Zinc Oxide (and) Butylene Glycol (and) Water – INCI may vary slightly by formulation

Appearance: Milky or white dispersion

Particle Size: Typically < 100 nm (nano range), surface-treated for stability and safety

Uses in the Cosmetic Industry
Nanosun-BS is primarily used in sun care and daily wear skincare products, with key roles including:

UV Filter: Provides broad-spectrum UV protection (UVA & UVB)

Physical Sunscreen: Acts as a mineral blocker of UV radiation without chemical absorption

Transparency: Designed to minimize whitening on skin, even with high SPF

Skin Soothing Agent: Zinc oxide offers additional benefits such as soothing sensitive or irritated skin

Stabilizer: May improve formulation stability in emulsions and suspensions

Common products include:

  • Sunscreen lotions and sprays
  • BB and CC creams with SPF
  • Daily moisturizers with UV protection
  • Baby sunscreens and sensitive skin formulas

Hazards and Safety Concerns

While nano zinc oxide is generally regarded as safe for topical use, there are a few considerations:

General Safety
Non-toxic & Non-irritant: When used externally, does not penetrate viable skin layers

Photostable: Does not degrade upon sun exposure

Low Sensitization Risk: Minimal allergy potential

Nanoparticle Considerations
Inhalation Risk: Avoid aerosol applications where zinc oxide nanoparticles could be inhaled (e.g., sprays), as this may cause respiratory irritation

Regulatory Attention: Must be clearly labeled as "nano" per EU Cosmetic Regulation when particle size is in nano range

Environmental Concerns: Potential effects on aquatic life if washed into water bodies, particularly in high concentrations

Regulatory Status
Approved as a UV filter in:

EU (Annex VI of Regulation EC No. 1223/2009)

USA (FDA) – Generally recognized as safe and effective (GRASE)

Australia, Japan, Korea, and other regions under specific concentration limits

1. CAS Number: 1314-13-2 (Zinc Oxide)
Other CAS numbers may apply for dispersing agents (e.g., Butylene Glycol: 107-88-0)

2. INCI Name: Zinc Oxide (and) Butylene Glycol (and) Water
INCI may vary slightly depending on the formulation base or dispersion medium.

3. Composition: Active Ingredient: Zinc Oxide (nano-sized, typically <100 nm)

Carrier/Dispersing Agents: Butylene Glycol, Water

Optional Coatings: Silica, triethoxycaprylylsilane, or other surface treatments for improved dispersion and skin safety

4. Purity Grade: Cosmetic Grade / Pharmaceutical Grade (where applicable)

Zinc Oxide purity: ≥ 99%

Complies with ISO 16128 natural origin standards if plant-based carrier is used

5. Appearance: Milky-white or white aqueous dispersion

Low viscosity, stable emulsion

No visible particles

6. Solubility: In Water: Insoluble (zinc oxide is suspended)

In Formulations: Dispersible in emulsions and compatible with oil-in-water and water-in-oil systems

Solvent Phase: Dispersing agents like butylene glycol help maintain uniformity

7. Preservation: May contain preservatives (e.g., Phenoxyethanol or Ethylhexylglycerin) to ensure microbial stability

Preservative-free options may be available upon request depending on supplier

8. Storage: Store in a cool, dry, and well-ventilated area

Protect from freezing, excessive heat, and direct sunlight

Recommended Storage Temperature: 5°C to 25°C

Shelf Life: 12–24 months (sealed, under ideal conditions)

9. Raw Material Sources: Zinc Oxide: Mined and purified from natural zinc ores or synthesized from zinc metal

Carriers: Synthetic (e.g., butylene glycol) or naturally derived depending on formulation

10. Manufacture: Produced via micronization and nano-sizing of zinc oxide followed by surface treatment

Dispersed into carrier medium using high-shear mixing or ultrasonication

Follows GMP-compliant processes for personal care materials

11. Animal Testing: Typically not tested on animals

Cruelty-free claims depend on supplier and third-party certification (e.g., Leaping Bunny, PETA)

12. GMO Status: Non-GMO – No genetically modified organisms used in production

13. Vegan Status: Vegan-friendly – No animal-derived ingredients involved in standard formulations

14. Proposition 65 (California): Not listed under California Proposition 65 as a known carcinogen or reproductive toxin

15. Warnings & Precautions: For external use only:

  • Avoid inhalation – not recommended for aerosolized/spray products due to nanoparticle safety guidelines
  • Avoid contact with eyes and mucous membranes
  • Ensure labeling compliance for “nano” materials in jurisdictions such as the EU (per Regulation EC No. 1223/2009)
  • May contribute to aquatic toxicity if released in large quantities into waterways

FAQ (Frequently Asked Questions)

Nanosun-BS is a high-performance nano zinc oxide dispersion designed for use in personal care and cosmetic products. It functions primarily as a broad-spectrum UV filter in sunscreens, day creams, and protective skincare formulations. Nanosun-BS is engineered to offer excellent transparency on the skin while maintaining high SPF efficacy.

CAS Number: 1314-13-2 (Zinc Oxide)
INCI Name: Zinc Oxide (and) Butylene Glycol (and) Water

Nanosun-BS is widely used in:
Mineral sunscreens (SPF products)
Moisturizers and day creams with sun protection
BB and CC creams
Sensitive skin and baby care formulations
After-sun and anti-pollution products

Nano zinc oxide in Nanosun-BS offers:
Broad-spectrum protection from UVA & UVB
Non-whitening effect on skin
Photostability – doesn’t degrade in sunlight
Gentleness – ideal for sensitive or acne-prone skin

Yes. Nanosun-BS is considered safe and effective for topical application. Regulatory bodies like the EU, FDA, and EWG approve nano zinc oxide for use in cosmetics, provided it is not used in inhalable (aerosolized) forms.

Depending on the formulation, Nanosun-BS may include mild preservatives such as Phenoxyethanol to ensure microbiological safety. Preservative-free options may be available upon request.

Yes. Nanosun-BS is:
Non-GMO
Vegan-friendly
Not tested on animals (supplier-dependent)
Free from parabens and chemical UV filters (when used as a physical sunscreen base)

Yes. In accordance with EU and other regulations:
It must be labeled as a "nano" material when applicable
Inhalation risks should be avoided—do not use in sprays or powders
It is not listed under California Proposition 65 as a hazardous substance

Store in a cool, dry place, away from direct sunlight and freezing temperatures. The recommended storage temperature is 5°C to 25°C. Shelf life is 12–24 months when unopened and properly stored.

Nanosun-BS uses nano-sized, surface-treated particles for improved skin transparency and dispersion. Unlike standard zinc oxide, it blends more easily into formulations without leaving a white cast.
