Formulation Questions: Facial Spray (Water/Silicone Mixing) and Vitamin A Body Oil
คำถาม
I have two formulation questions:
1. Facial Spray Formulation
I am developing a facial spray with the following ingredients:
- Matrixyl™ 3000
- Argireline®
- Lift-Now™
For the base, I am using:
- Water (Can I use mineral water instead of distilled water?)
- SiliSilk™ (ผงซิลิโคนนุ่มลื่น)
- Cyclomethicone
- Aloe Vera Extract
- Glycerin (Vegetable) 99.8%
I received feedback that if I include Cyclomethicone, I need to use SiliSolve™ to emulsify the silicone with water. A suggested formula adjustment is:
- Water 70%
- Cyclomethicone 10%
- SiliSolve™ 1%
- Other ingredients (including the active ingredients, SiliSilk™, Aloe Vera Extract, Glycerin) for the remaining percentage.
The feedback also mentioned that adding too much Glycerin might counteract the light feel of Cyclomethicone and make the texture feel heavy.
Could you provide guidance on how to properly combine water and Cyclomethicone in this spray formulation and how the ingredients interact?
2. Vitamin A in Natural Oil Formulation
I want to mix Vitamin A (retinyl palmitate / retinol palmitate) with a natural oil for body massage.
- Do I need to warm the oil before mixing?
- Can I just mix it in and use it immediately?
Could you advise on the correct mixing procedure for adding Vitamin A Palmitate to natural oil?

Facial Spray Formulation
Regarding your facial spray formulation with Matrixyl™ 3000, Argireline®, Lift-Now™, SiliSilk™, Cyclomethicone, Aloe Vera Extract, and Glycerin:
- Active Ingredients: Matrixyl™ 3000 and Argireline® are excellent peptides for anti-aging, working to stimulate collagen and reduce muscle tension, respectively. Lift-Now™ provides a temporary skin tightening effect, which is great for use before makeup or during the day.
Base Ingredients:
- Water: Using distilled water (or deionized water) is recommended over mineral water in cosmetic formulations. Distilled water is pure and free from minerals that could potentially interact with other ingredients or affect the stability of your spray.
- Cyclomethicone: This is a silicone oil that provides a light, smooth feel and evaporates quickly. However, it does not mix with water.
- SiliSilk™: This silicone powder can provide a soft feel and help absorb oil. SiliSilk™ WO is dispersible in both water and oil phases.
- Aloe Vera Extract: This is water-soluble and adds moisturizing and soothing properties.
- Glycerin: This is a humectant that helps attract moisture. However, as noted in the reply you received, using too much Glycerin in a formula containing Cyclomethicone might counteract the light, non-greasy feel that Cyclomethicone provides, potentially making the spray feel a bit heavy or sticky.
Combining Water and Cyclomethicone: You cannot simply mix water and Cyclomethicone. You need an emulsifier to create a stable mixture (an emulsion). As suggested, SiliSolve™ is a suitable water-to-silicone emulsifier for this purpose.
Suggested Base Adjustment: To incorporate Cyclomethicone into your water-based spray, you would need to use an emulsifier like SiliSolve™. A possible approach is to create a water-in-silicone emulsion. The general procedure involves mixing SiliSolve™ with the silicone phase (Cyclomethicone and potentially SiliSilk™ WO if using that type), and then gradually adding the water phase (water, Aloe Vera Extract, Glycerin, and the water-soluble peptides Matrixyl™ 3000, Argireline®, Lift-Now™) while continuously mixing until emulsified.
Order of Addition: Water-soluble ingredients like Matrixyl™ 3000, Argireline®, Lift-Now™, Aloe Vera Extract, and Glycerin should be dissolved in the water phase. Cyclomethicone and SiliSilk™ WO (if using) should be in the silicone/oil phase with SiliSolve™. The water phase is then added slowly to the silicone phase with mixing.
Final Note: Ensure the temperature is below 40°C when adding the peptides (Matrixyl™ 3000 and Argireline®).
Vitamin A in Natural Oil Formulation
Regarding mixing Vitamin A (retinyl palmitate) with natural oil for body massage:
- Solubility: Vitamin A Palmitate is oil-soluble, so it can be mixed with natural oils.
- Mixing Procedure: Vitamin A Palmitate is often stored in the refrigerator, where it can solidify or become semi-solid. Before mixing it with oil, you should allow it to warm up to room temperature until it becomes liquid. If it's still solid or very viscous, you can gently warm the Vitamin A Palmitate itself (not the bulk oil yet) in a warm water bath until it liquefies. Once liquid, you can mix it into your natural oil base. You do not necessarily need to heat the entire volume of natural oil, but ensuring both the Vitamin A and the oil are at a similar, slightly warm temperature (below 40°C) can help with easier and more uniform mixing.
- Protection: Vitamin A is sensitive to light and heat. Store the final oil mixture in an opaque bottle away from direct sunlight and heat to maintain its potency.
