Formulation Evaluation

Based on the formulation you provided and the information about the ingredients:

The proposed formula for a 100ml Pillow Mist is:

• Flora Solve Clear 5%
• Essential Oil Blend 30%
• Phenoxyethanol SA 1%
• Water 64%

Let's evaluate this formulation:

Essential Oil Blend (30%) and Flora Solve Clear (5%)

Flora Solve Clear is used to solubilize essential oils or fragrance oils in water. According to the product description for Flora Solve Clear, the recommended usage ratio is typically 2-5 parts Flora Solve Clear to 1 part essential oil or fragrance.

In your formula, you have 30% Essential Oil Blend and 5% Flora Solve Clear. This gives a ratio of 5 parts Flora Solve Clear to 30 parts Essential Oil Blend, or 1 part Flora Solve Clear to 6 parts Essential Oil Blend (1:6 ratio).

This ratio (1:6) is outside the recommended range of 2:1 to 5:1 (Flora Solve Clear : Essential Oil). You are using significantly less solubilizer than needed for the amount of essential oil.

With only 5% Flora Solve Clear attempting to solubilize 30% essential oil, the essential oil will likely not fully dissolve in the water phase and will separate. This will result in a cloudy or separated product, not a clear mist.

Furthermore, a 30% concentration of essential oil in a mist is very high and might cause skin irritation or other issues. The product description for Flora Solve Clear also notes a limitation that it "Cannot contain a large proportion of perfume. This is because a large proportion of Flora Solve™ Clear must be used and the spray becomes too thick. and cannot spray". While 5% Flora Solve Clear isn't a large proportion, the 30% oil requires a much higher amount of solubilizer, which would make the final product too thick to spray.

To properly solubilize 30% essential oil, you would need between 60% (30% * 2) and 150% (30% * 5) of Flora Solve Clear, which is not practical for a mist formulation.

Phenoxyethanol SA (1%)

Phenoxyethanol SA is a broad-spectrum preservative. The recommended usage rate for Phenoxyethanol SA is typically 0.5-1.25%. Your proposed usage of 1% is within this recommended range. The product description mentions it can be dissolved in water (up to 1.0%) and oil (up to 0.6%). While the high oil content might pose some solubility challenges for the preservative in the oil phase, the primary issue with your formula is the solubilization of the essential oil.

Conclusion

The proposed formula is not correct because the amount of Flora Solve Clear (5%) is insufficient to properly solubilize the high concentration of Essential Oil Blend (30%). This will lead to separation of the oil and water phases. The percentage of essential oil is also likely too high for a typical mist application.

To create a stable and effective mist, you would need to either significantly increase the amount of Flora Solve Clear (which might make the product too thick) or, more practically, significantly reduce the percentage of the Essential Oil Blend to a level that can be effectively solubilized by a reasonable amount of Flora Solve Clear. A more typical concentration for essential oils in a mist might be in the range of 1-5%, which would require a manageable amount of solubilizer.
