Niacinamide, Vitamin B5 & Vitamin F Sunscreen

Ingredient Breakdown & Functions

1. UV Filter System (Broad‑Spectrum Protection)

• Ethylhexyl Methoxycinnamate (Octinoxate): UVB absorber that helps prevent sunburn.
• Butyl Methoxydibenzoylmethane (Avobenzone): UVA absorber (UVA‑I & II); requires stabilization.
• Benzophenone‑3 (Oxybenzone): Broad‑spectrum filter and stabilizer for avobenzone; subject to environmental regulatory scrutiny.
• Titanium Dioxide: Physical filter that reflects and scatters UV rays; helps counter white cast.
• Suncat DE: Encapsulated combo of Octinoxate, Avobenzone, Oxybenzone; improves photostability, reduces irritation, enhances dispersion and water resistance.

2. Emollients / Skin Conditioners

• Light Liquid Paraffin: Occlusive to prevent moisture loss.
• Isopropyl Myristate: Enhances spreadability, may increase active uptake.
• Ceto Stearyl Alcohol: Fatty alcohol, acts as emollient and co‑emulsifier.
• Stearic Acid: Thickener and emulsifier that adds creaminess.
• Ethylene Glycol Monostearate: Opacifier that adds pearly texture and emulsifies.

3. Humectants / Moisturizers

• Glycerin: Classic humectant that maintains skin hydration.
• Propylene Glycol & 1,3‑Butylene Glycol: Dual humectant and penetration enhancer roles.
• Niacinamide: Improves barrier, evens tone, reduces pores, offers antioxidant benefit.
• Vitamin B5 (Panthenol): Hydrates, soothes, supports repair.
• Vitamin F (Linoleic Acid): Essential fatty acid that supports barrier and reduces inflammation.

4. Silicones & Texture Enhancers

• Cyclopentasiloxane: Volatile silicone providing a silky feel.
• Simethicone: Anti‑foam agent that improves stability and texture.

5. Film‑Formers / Stabilizers

• Polyvinyl Pyrrolidone (PVP): Forms adherent film to hold actives in place.
• Carbomer: Thickener that stabilizes emulsions.
• Triethanolamine: Neutralizes carbomer and helps buffer pH.

6. Antioxidants & Anti‑Pollution Actives

• Infraguard (Caesalpinia + Helianthus extracts): Provides anti‑pollution and DNA‑repair support.
• BHT & BHA: Strong antioxidants that stabilize oils and UV filters.

7. Preservatives

• Phenoxyethanol & Ethylhexylglycerin: Broad‑spectrum preservation, with added skin conditioning.
• Di‑Sodium EDTA: Chelates metals to boost preservative efficacy.

Formulation Claims & Benefits

• Broad‑spectrum SPF: Made possible by the synergy of chemical & physical filters.
• Moisturizing: Glycerin, glycols, Panthenol provide deep hydration.
• Non‑greasy finish: Silicones and isopropyl myristate deliver a dry-touch feel.
• Anti‑pollution & antioxidant defense: Infraguard complex, niacinamide, BHT/BHA combat environmental stress.
• Barrier support & skin brightening: Niacinamide, Vitamin F, Panthenol help restore and renew.
• Stabilized, photoprotective system: Suncat DE with antioxidant support enhances photostability.

Formulation Notes

• Avobenzone stability: Well‑supported by Suncat DE and benzophenone‑3.
• Irritation potential: Benzophenone‑3 and alcohol derivatives may irritate sensitive skin.
• Regulatory caution: Oxybenzone is banned in Hawaii, Palau and other regions.
