Question
I want to dissolve Salicylic Acid (BHA) for use on acne-prone skin. I'm considering dissolving it in Jojoba Oil or another base.
- Can Salicylic Acid be dissolved in oil, specifically Jojoba Oil? If so, what is the typical solubility limit (e.g., grams per 100 grams of oil)?
- Is using Jojoba Oil as a base suitable for acne-prone skin? Are there any potential issues?
- What other bases or solvents are recommended for dissolving Salicylic Acid, and why?
Answer
Based on the staff's reply:
- Salicylic acid (BHA) can dissolve in oil, including Jojoba oil, typically around 2 grams per 100 grams of oil.
- However, using Jojoba oil for acne-prone skin is not recommended. Jojoba oil is very similar to skin's natural oil, and applying it to acne-prone areas can potentially worsen clogged pores.
- For dissolving Salicylic acid, it is recommended to use glycols, such as propylene glycol. Salicylic acid dissolves well in glycols.
- Salicylic acid is insoluble in water, and the presence of water in a mixture can cause it to precipitate (settle out). Mixing it in a base without water, like glycols, helps prevent precipitation, especially if stored at room temperature.
