Dissolving Calcium Thioglycolate & Calcium Hydroxide in Hair Removal Foam
Question
How can Calcium Thioglycolate be dissolved in water for a hair removal foam formula? When mixed with water, it forms hard lumps even after blending. Please advise on the dissolution steps for the following formula: Water = 69.90%, Cond-Foam = 15%, Disodium EDTA = 0.1%, Mild Preserved Eco = 1%, Glycerin = 5%, Calcium Thioglycolate = 7.50%, Calcium Hydroxide = 1.50%. Sodium Hydroxide or Potassium Hydroxide is used to adjust pH to 12-12.5.
Answer
Hello,
The issue of Calcium Thioglycolate forming hard lumps when mixed with water in your hair removal foam formula might be due to incorrect dissolution steps. Calcium Thioglycolate and Calcium Hydroxide are powdered ingredients that need to be properly dissolved in water first.
Here are the recommended steps for dissolving Calcium Thioglycolate and Calcium Hydroxide in your formula:
- Prepare the water in your mixing vessel.
- Slowly add Calcium Thioglycolate and Calcium Hydroxide to the water gradually, while stirring or blending continuously and consistently.
- Stir or blend the mixture thoroughly until all the powder is dispersed and dissolved in the water. This may take some time and sufficient mixing to ensure no powder remains undissolved or clumped.
- Once Calcium Thioglycolate and Calcium Hydroxide are well dissolved in the water, then gradually add the remaining ingredients according to your formula (e.g., Disodium EDTA, Glycerin, Cond-Foam, Mild Preserved Eco) and mix until homogeneous.
- Finally, adjust the pH of the formula with Sodium Hydroxide or Potassium Hydroxide solution as indicated in your formula, to achieve a pH in the range of 12-12.5.
Adding the powders gradually to the water while stirring continuously will help prevent clumping and facilitate easier dissolution.
Hope this advice is helpful. Feel free to ask if you have any further questions.
