Emulsifiers for Light, Moisturizing Lotion for Combination Skin and Preservatives for Yeast Formulation
Question
I have skin that is oily on the outside but dry inside. I need recommendations for emulsifiers to create a lotion.
Properties of Emulsifier needed:
- Makes the lotion light-textured, but can retain moisture.
- Is the safest ingredient possible.
I also need advice on preservatives.
- Which preservative is the safest? (Are there natural options?)
- If my formulation contains yeast, which preservative should I use?
Answer
Emulsifiers for Light, Moisturizing Lotion
For skin that is oily on the outside but dry inside, aiming for a light texture that retains moisture, the staff recommended Light Cream Maker and Satin Mousse. These emulsifiers are suggested for their ability to create lotions with a desirable light feel while helping to keep the skin hydrated.
Preservatives
You asked about the safest preservatives, including natural options, and what to use if your formulation contains yeast.
- Natural Preservatives: While natural preservatives do exist, they often come with limitations that can make formulating challenging. For example, some natural options like Lactic Acid can lower the pH of the formulation, which might not be suitable for all recipes and can also have unintended effects like exfoliating the skin if used at higher concentrations.
- Preservatives for Yeast: To recommend a specific preservative that is effective against yeast in your formulation, it is necessary to know the specific type of yeast you are using. Different preservatives have varying effectiveness against different types of microorganisms, including yeast.
Unfortunately, I was unable to retrieve detailed product information for the specific emulsifiers and preservatives mentioned at this time. For the most suitable preservative for your formula containing yeast, please provide the specific type of yeast being used.
