Question
I am developing a non-SLS shampoo formulation and have some questions regarding ingredient percentages and formulation steps:
- How many percent of Clear Clean should be used in the formula?
- How many percent of Ethoxydiglycol should be used? What is the principle for determining the appropriate amount?
- Regarding Menthol 1% and Peppermint Oil 1%, the staff mentioned these percentages are quite high and might cause irritation. What would be a recommended starting percentage?
- When adjusting the pH to 5.5 using NaturePreserve 1.25% and Citric Acid q.s., should NaturePreserve be added before measuring pH and adding Citric Acid?
Additionally, based on my formula using Coco-Betaine 20% and Lauryl Glucoside 10%, the total surfactant level is 30%. Is this acceptable for high cleanliness?
Answer
Based on the provided conversation regarding a non-SLS shampoo formulation:
- Coco-Betaine: An example formula used 20%. The staff noted that the total surfactant level (including Coco-Betaine at 20% and Lauryl Glucoside at 10%) at 30% is quite high but acceptable for high cleanliness.
- Creamy Foamer: An example formula used 10%.
- Clear Clean: The staff recommended starting at 3%.
The optimal percentage for each ingredient can be adjusted depending on the desired cleaning strength and foaming properties of your shampoo. It's often best to start with a recommended range or a lower percentage and test the formula, adjusting as needed.
