คำถาม
I have a sunscreen formulation with Titanium Dioxide and Zinc Oxide. I have two questions:
- Can I substitute
Safe-B3™ (Vitamin B3, Niacinamide)withAloe Vera Extract (extraction ratio 10:1 FullAssay™)at the same quantity? - Can
Encapsulated Salicylic Acid (Liquid, Timed-Release, Wash-Off)be mixed directly with plain water for exfoliation?

Sunscreen Formulation Advice
Based on your formulation and the discussion:
- Caprylic/Capric Triglyceride: As confirmed, this ingredient is also known as Fractionated Coconut Oil. It acts as a lightweight emollient in your formula.
- Improving Efficacy / Making BB/CC Cream: The current formulation is suitable for sun protection. To enhance the texture for a smoother feel or to create a BB/CC cream effect that helps blur imperfections, adding Silica is a good suggestion. A product like UltraBlur™ (Skin Blurring Silica) is designed specifically for this purpose.
- Substituting Vitamin B3 with Aloe Vera Extract: You can substitute Safe-B3™ (Vitamin B3, Niacinamide) with Aloe Vera Extract (extraction ratio 10:1 FullAssay™). However, as Aloe Vera Extract contains electrolytes, it might reduce the viscosity of your cream. You may need to increase the amount of Light Cream Maker™ to achieve the desired consistency.
Your base formulation with Titanium Dioxide and Zinc Oxide provides good sun protection. Adding ingredients like Silica can improve the aesthetic feel and performance for makeup-like effects.
Encapsulated Salicylic Acid and Water
Regarding mixing Encapsulated Salicylic Acid (Liquid, Timed-Release, Wash-Off) with plain water for exfoliation:
- Yes, you can mix Encapsulated Salicylic Acid directly with water.
- Important Considerations: Since this mixture would be prone to microbial growth, you must either include a preservative in the formulation or store it in the refrigerator and use it very quickly. Ensure all mixing processes are highly hygienic to prevent contamination.
- Note that the description for Encapsulated Salicylic Acid (Liquid, Timed-Release, Wash-Off) indicates it is primarily for wash-off products. If you intend to leave the product on the skin, you should consider using a different type of Encapsulated Salicylic Acid designed for leave-on applications.
- Also, be aware that Encapsulated Salicylic Acid is incompatible with certain thickeners and bases, including Light Cream Maker™ and Aloe Vera Gel/Hyaluronic Gel. If you were to incorporate it into a more complex formula, you would need to choose compatible ingredients.
Remember to always test new formulations on a small area first.
