คำตอบ
Subject: Preservation in Yogurt and Making Cream
Regarding your questions:
Using yogurt on the face and preservation: It is not possible to add preservatives to yogurt for cosmetic use and store it outside the refrigerator. Preservatives would kill the beneficial bacteria in the yogurt, which are part of its active components. The main active ingredient in yogurt for skin benefits is Lactic Acid. You can use Lactic Acid directly in your formulations. You can find more information about Lactic Acid here.
Mixing concentrated salt water and fractionated coconut oil: To mix water (concentrated salt water) and oil (Fractionated Coconut Oil) to form a cream or gel, you will need an emulsifier. Since the formulation contains water, you will also need a preservative to prevent microbial growth. The staff recommended reviewing the guide for beginners on creating cream textures, which provides detailed information on emulsifiers, preservatives, and formulation basics. You can find the guide here.
