Using Goat Milk Powder in Glycerin Soap: Benefits and pH Compatibility

Based on the information provided:

• Regarding dissolving the goat milk powder in water first: While it is a common practice to dissolve powders before adding them to formulations, the main challenge with using goat milk powder in glycerin soap is the high pH of the soap base.
• Regarding temperature tolerance: Goat milk can withstand temperatures of around 40-50°C for a short period without losing its quality.
• However, the staff advises that due to the relatively high alkaline pH of glycerin soap, the beneficial proteins from goat milk tend to be destroyed. Therefore, using goat milk powder in solid glycerin soap is primarily for marketing purposes and you should not expect it to provide significant skin benefits.
• If you wish to make soap where the goat milk provides skin benefits, the staff recommends considering making liquid soap with a pH range of 4-6.

So, while the temperature of 40-45°C during glycerin soap making is within the short-term tolerance of goat milk, the high pH of the soap base is the factor that prevents the goat milk from providing its full benefits.
