Adjusting Facial Mist Formula: Preservative and Texture
Question
I am formulating a hydrating and nourishing facial mist for normal skin using the following ingredients:
- Aloe barbadensis leaf juice (1%)
- Saccharide Isomerate (MOIST72, 1%)
- Polyquaternium-51 (Waterlock, 1%)
- Phenoxyethanol (0.5%)
I plan to use Mineral Water as the base. Is this formula suitable for a facial spray? Are there any concerns regarding the preservative (Phenoxyethanol) for a product that might get into the eyes? How can I improve the texture to reduce dripping and help it adhere better to the skin?
Answer
Based on your goal to create a hydrating and nourishing facial mist for normal skin, and considering the provided recipe and the staff's advice, here are the recommended adjustments:
The staff's suggestions are excellent for improving the safety and feel of the facial mist:
- Preservative Change: It is highly recommended to replace Phenoxyethanol (0.5%) with 1,2-Hexanediol (3%). As the staff mentioned, 1,2-Hexanediol is a gentler preservative, which is safer for a spray product that may come into contact with the eyes.
- Optional Texture Improvement: You can optionally add Glycerin or Butylene Glycol at 1-3% to help the mist adhere better to the skin and reduce dripping.
The other ingredients in your original recipe – Aloe barbadensis leaf juice (Aloe Vera Extract), Saccharide Isomerate (MOIST72), and Polyquaternium-51 (Waterlock) – are good choices for hydration and nourishment and are suitable for normal skin at the percentages you listed (1% each). Increasing these might make the mist feel slightly sticky.
Here is the adjusted formula based on the staff's recommendations (using 1,2-Hexanediol 3% and adding Glycerin 2% as an example):
- Mineral Water (based on the link provided, ID 838): 92%
- Aloe barbadensis leaf juice (ID 76): 1%
- Saccharide Isomerate (MOIST72, ID 257): 1%
- Polyquaternium-51 (Waterlock, ID 258): 1%
- 1,2-Hexanediol (ID 886): 3%
- Glycerin (ID 143): 2% (Optional - adjust Mineral Water percentage if not added or if using a different percentage/Butylene Glycol)
Mixing Instructions:
- Combine Mineral Water, Aloe barbadensis leaf juice, Saccharide Isomerate, and Polyquaternium-51. Stir well until fully mixed.
- Add 1,2-Hexanediol and optional Glycerin (or Butylene Glycol). Stir again until everything is homogenous.
This adjusted formula provides good hydration and nourishment suitable for normal skin while using a gentler preservative system appropriate for a facial spray.
