I've been making fresh goat milk soap for over 20 years, and am an experienced soap maker. I have not made any changes to my process or formula. Until now my soap has been perfect. The last three batches have all had small brown spots throughout. NOT dreaded orange spots. This is UNSCENTED plain soap. The spots are very small and look like soap that's had tea or herbs added. I am using frozen goat milk from a good supplier that has different breeds of goats. Could these spots be caused by milk sugars in the soap? They seem to be cosmetic only. I soap at low temp, around 85 degrees. I'm stumped, wondering if the milk came from a goat that just has some extra rich milk with a higher sugar content than other goats might have? Has anyone experienced this with their goat milk soaps?
