Inquiries on Vitamin C Usage, Acne Ingredients, Oxybenzone Solubility, and Packaging Suitability

Here is the information based on the provided forum thread:

Natural-C Glycol™ (Stabilized Vitamin C Glycol)

• It can be used around the eyes, but it is recommended for nighttime use to avoid potential eye irritation.
• It can be used during the day or in sunlight. While vitamin C degrades faster in sunlight, skin absorption is quick enough that degradation before absorption is not a significant issue.

nano silver and White Egg Enzyme

• Both ingredients kill bacteria that contribute to acne inflammation.
• They do not help with clogged pores.

nano silver as a preservative

• Using 0.3% nano silver is likely sufficient for a jar cream.
• However, preservative effectiveness depends on the entire formula. A Challenge Test is the only way to confirm sufficient preservation in a specific formula.

Oxybenzone solubility

• Oxybenzone solubility:
  • 17% in Coco Wash™
  • 15% in LipidSoft
  • 14% in Fractionated Coconut Oil
  • 6% in Ethyl Alcohol
• Using 10% LipidSoft should be sufficient to dissolve 5% Oxybenzone.

Packaging materials (polyethylene, polypropylene, nylon)

• Good quality, sufficiently thick polyethylene (PE) and polypropylene (PP) plastics are suitable for general cosmetic packaging.

Polystyrene packaging

• Information on the suitability of polystyrene plastic for cosmetic packaging, especially for acidic, sunscreen, or high-oil creams, is not available.
