Hi Sandra, really appreciate your response and all the helpful advice. Will let you know how it goes. Look forward to more videos from you.. everything is so well explained.
Thank you for sharing this video. It is really helpful for a first time solid shampoo bar makers like me:) May I ask, if I were to add a tiny bit of clay or spirulina or a hair friendly powdered herb, at what point would I add it and how much. Thanks for any help with this😇
Hi Diana. For this particular recipe I would add between 3 & 5% clay or 1 to 2% spirulina or herb. You would need to reduce the SCI by the same percentage that you are adding the other ingredient. For example; if you add 4% rose clay, you would reduce the SCI by 4%. I would add the powdered ingredients when the liquid ingredients are added. Spirulina has a tendency to smell a bit fishy at times but at such a low percentage I don’t believe it would change the scent of the shampoo bars. I hope this helps and I would love to know how they turn out for you!
Hi Tammy! BTMS-25 contains less active conditioning agents (25% Behentrimonium Methosulfate) than BTMS-50 (50% Behentrimonium Methosulfate) and it also won't emulsify this formulation as well as BTMS-50. In order to keep the potency of the conditioning and emulsifying properties, I would stick with BTMS-50. If you did use BTMS-25 in place of the BTMS-50 you would have to use almost twice as much BTMS-25 to get the conditioning effect then add a co-emulsifier like cetyl alcohol in order for it to emulsify properly. You would also need reduce one or more of the other ingredients in order to keep the formulation at the correct percentages but it may reduce the efficacy of the shampoo bar. I hope this information is useful and if you have any more questions you can always reach me through RU-vid or you can email me at sandrav@sandravbathandbody.com and I’ll be happy to help.
The pH of our shampoo bars is around 5 (+/- 0.5). With the recommended usage rate of Polyquaternium 7 being 1-4%, you would need to reduce one or more of the other ingredients by the same percentage that you add Polyquaternium 7. You would include it in the formula at the cool down phase. For example; If you want to use 2% Polyquaternium 7, you would add .6 oz (17 grams) to the cool down phase and reduce the SCI by .42 oz (12 grams) and the CAPB by .18 oz (5 grams). Let me know how it turns out for you. Have fun and be blessed.
