Are you are concerned with all of the chemicals that are present in your shampoo, you may want to consider making your own shampoo bar. Here I found a recipe that appeared on Suite 101 to make some. Give it a try and let us know how it turns out.
To make a 4 pound batch
12oz Coconut Oil
19oz of mid grade Olive Oil (not virgin,not pomace)
12oz Caster Oil
16oz distilled water
1/2oz rosemary oil (not to be used if expectant lady using product replace with essential oil of choice)
Observing usual soap making precautions.
Especially melting oils, mixing water&Lye (this is a fairly large batch).
Combine Oils and Lye @ 100 F. Stirring constantly (avoid splashing) till trace, add essential oil(rosemary, etc) stir in then pour into mold, lined with saran wrap or Vaseline. Insulate for 24 hours. Uncover & leave in mold until soap is hard enough to take out.(usually 4-6 days)When hard enough cut into bars, then cure for 4-5 weeks. This soap remains soft for quite a considerable time longer than normal cold pressed soap, IT DOES EVENTUALLY HARDEN to nice bars. Personally a nice shampoo bar......
My little question to soap makers is "Does anyone know the SAP value of Grapeseed Oil, no not grapefruit seed oil, just grapeseed oil?"
