Tear free homemade soap?

[JillGat]

Is there a melt and pour soap that is tear free? I make soap with lye, but I'm thinking melt and pour might be more likely to have a version for babies.

Tear free shampoo is usually the same pH as human tears (which is pretty much a neutral pH of 7). It is not possible to make a lye based soap with such a low pH, so synthetic detergents are usually used to achieve this. If you can find a melt and pour with a pH of 7 then that will be tear free (or as close as you can get). Obviously there could be other irritants in the soap itself that you might need to watch out for.

Thanks. I'm actually trying to formulate a dog shampoo! I hadnt thought of using my shampoo bat recipe, for some reason and it very well may be no tears.

The "no more tears" line is a stretch on how fast potassium based soaps rinse away. There's still tears, just not as bad and for like 10% of the time.

However, I've seen PG in some M&P base recipes. That's also an ingredient in eye drops used to prevent that rinse.

hopefully helpfull

Ooops, "dog shampoo"? might want to ask a vet about their eyes! Different species!

Oh - fur babies . I make a cold processed soap for mine - with neem oil in it. Haven't had a problem yet but i do avoid their eyes. But yeah - shampoo bars too I guess.

@JillGat, have you looked into Syndopour by Stephenson? I bought Syndopour 200 to make shampoo bars for my fur babies. (In fact, they are getting a bath today!) Syndopour 200 can be used for bath and face bars, too. Various suppliers carry it, but the best information is on the Stephenson website.

Stephenson recently added a Syndopour Shampoo Base, which is supposed to allow for more additives. I haven’t tried it yet.

They also make a conditioner base.

Although I use these with my Brittany Spaniels, the bars are great for travel. Hope this helps!
