Adding Rose Hip Oil to Hada Labo and Formulation Issues

Question

I am currently mixing Hada Labo with Vitamin C L-Ascorbic Acid. I would like to know if I can add Rose Hip Oil to this mixture, what the recommended ratio would be, and if Rose Hip Oil is available in smaller sizes (20-30ml). I understand that Hada Labo is likely a water-based formula without emulsifiers, which would cause the oil to separate. Could you confirm this and explain why adding oil directly isn't recommended? Also, could you elaborate on the suggested alternative formulation similar to Hada Labo, using ingredients like Water, Double Hyaluronic Acid 5%, Silicone Quick-Cond 2%, Rose Hip Oil 5-10%, Satin Cream Maker 1%, and Phenoxyethanol SA 1%?

Adding Rose Hip Oil to Hada Labo + Vitamin C

You are currently mixing Hada Labo with Vitamin C L-Ascorbic Acid. You asked if you can add Rose Hip Oil to this mixture and in what ratio, and if smaller sizes of Rose Hip Oil are available.

Based on the previous discussion, adding Rose Hip Oil directly to a Hada Labo product is generally not recommended. Hada Labo products are typically water-based and do not contain the necessary emulsifiers to properly combine oil and water. Adding oil without an emulsifier will cause the mixture to separate.

Therefore, there is no recommended ratio for adding Rose Hip Oil directly to your Hada Labo + Vitamin C mixture, as it will not form a stable, homogenous product.

Regarding the size of Rose Hip Oil, the descriptions for Rose Hip Oil (Extra Virgin) and Rose Hip Oil (Virgin, Fresh) do not specify if 20ml or 30ml sizes are available. Please check the product listing for available sizes.

As suggested previously, if you wish to use Rose Hip Oil in a water-based formulation, it is better to create a new formulation that includes ingredients like Water, Double Hyaluronic Acid, an emulsifier such as Satin Cream Maker, a silicone like Silicone Quick-Cond (PEG-12 Dimethicone), the oil itself (Rose Hip Oil), and a preservative like Phenoxyethanol SA (Optiphen Plus). This approach ensures the oil is properly dispersed and the formulation is stable.
