I want to purchase 1 kg of Absolue Soft Cream Base to use as a morning cream before makeup. I plan to add the following ingredients: 1. `Panthenol ( Pro Vitamin B5 , DL- Panthenol , Powder)` 1%: Should I add this directly to the cream, or should I mix it with water first? 2. `Capryloyl Salicylic Acid (LHA) Powder` 1%: Can I add this directly to the cream base? Will it dissolve since the base contains oil? If it doesn't dissolve, what should I do? Should I heat the cream base? If so, what temperature should I heat it to ensure the active ingredients from the manufacturer are not affected? 3. `Pure-Adenosine` 0.5%: Can this be dispersed directly into the cream after adding the ingredients from steps 1 and 2? If not, what should I do? 4. Based on steps 1-3, are there any additional ingredients needed for mixing? If so, please provide the ingredient name, percentage, and method so I can purchase them together. 5. After mixing according to the recommendations, will the cream feel oily? The base already contains silica. If it feels oily, what should I add to reduce oiliness? (Especially since I apply sunscreen afterwards, which is very oily). Please provide a link to the ingredient, percentage, and method.

I have purchased Absolue Soft Cream Base and plan to mix it with other ingredients, specifically [active ingredients in water] or [active ingredients in oil]. I previously saw a question about the maximum amount of [active ingredients in water] that could be added to Absolue Soft Cream Base, and the staff replied that 10% is acceptable. I have the following questions: 1. If I add [active ingredients in water] at a proportion of 20% (20 parts active ingredients in water : 80 parts Absolue Soft Cream Base), would the cream's viscosity change too much? Would it become loose like a lotion, or would it still retain a cream consistency? 2. If I add [active ingredients in oil] at a proportion of 20% (20 parts active ingredients in oil : 80 parts Absolue Soft Cream Base), would the cream's viscosity change too much? Would it become too sticky, or would the texture still be acceptable as a cream? 3. If I add either [active ingredients in water] or [active ingredients in oil] at a proportion of 20%, would this affect the preservative ability of the base cream? What is the maximum proportion of active ingredients that can be added without compromising the preservative ability of the base cream?
