Replacing Lauryl Glucoside with Coco Wash/Coco-Betaine in Facial Cleanser
Question
I want to replace Lauryl Glucoside in a facial cleanser formulation to make pH adjustment easier. I was considering using Coco Wash (PEG-7 Glyceryl Cocoate), but also heard Coco-Betaine is a good alternative for cleansing.
If I use Coco-Betaine as the primary surfactant in a facial cleanser, what is a recommended starting percentage?
Answer
Replacing Lauryl Glucoside with Coco Wash
Regarding your question about replacing Lauryl Glucoside with Coco Wash to simplify pH adjustment, it is possible, but there are some points to consider based on the properties of each ingredient.
Coco Wash (PEG-7 Glyceryl Cocoate) has a pH of around 6-7, which is more neutral and might be easier to work with compared to ingredients that require significant pH adjustment. However, its primary function is as a very mild surfactant that provides softness and smoothness. It is not ideal as the main cleansing agent in a facial wash because its cleaning efficiency is lower than Lauryl Glucoside.
As suggested, Coco-Betaine (Coco-Betaine) is a better alternative for facial cleansing. It is a mild surfactant derived from coconut oil, known for its good foaming ability and conditioning properties for skin and hair. While its cleaning efficiency is also not very high on its own, it performs better as a cleanser than Coco Wash.
A good approach for a facial cleanser could be to use Coco-Betaine, or a combination of Coco-Betaine and Coco Wash. If you plan to use Coco Wash at 4-6%, a suggested starting point for Coco-Betaine is around 10% to achieve sufficient cleansing power while maintaining mildness and good foam.
In summary:
- Coco Wash: Very mild, good for softness/smoothness, suitable for makeup removers or as a secondary additive for moisturizing. Lower cleaning power.
- Coco-Betaine: Mild, good foaming, better cleansing power than Coco Wash, conditioning properties. A better primary surfactant for facial wash compared to Coco Wash alone.
Using Coco-Betaine, possibly combined with a small percentage of Coco Wash for added mildness and feel, would likely give better cleansing results for a facial wash compared to using Coco Wash as the sole or primary surfactant.
