Always go to oil for all products. Consistent good quality and excellent price.
I am so happy I with this recipe and assessment! If you're not new to liquid soap making I highly recommend it. It creates a beautiful lathering soap and very easy to make with videos available. Don't be afraid of liquid soap making! Thank you to all CSS team, all your hard work is appreciated :)
The product makes up beautifully and the combination of a ready made CPSR is an absolute dream; making an otherwise very complex process very user friendly and transparent meaning that the focus as a small business can be on other areas of compliance.
Thank you
I love this assessment, the recipe is easy to follow and Tanias video is super helpful to check consistency and how it should be looking! My husband (aka guinea pig) absolutely loves it, he’s threatened divorce if he finds his personal stash empty when he wants to use it 😂
I ordered a CPSR Beef Tallow kit from Cosmetic Safety Solutions. The service i received was outstanding. The order was delivered next day together with the Recipe and easy to follow Method to allow me to manufacture my first batch with complete success. The follow up communication via e mail was brilliant and answered all of my subsequent questions speedily. Within one week i was able to refine my manufacture process and produce Tallow Balm and Whipped Tallow ready for market. I would not hesitate to recommend Cosmetic Safety Solutions to anyone looking for a professional partner in the supply of Skin Care products. Outstanding.
Wow, I cant say enough great things about this recipe and assessment, the fragrances are gorgeous, the micas are beautiful to work with and the recipe is simple but pure indulgence. Outstanding CSS once again 👏
Started making these soaps and they are wonderful. Lather is great and the smell is amazing.
I use this personally and it is just brilliant. It transforms skin and a little really does go a long way. I have lots of repeat customers of all ages for this and they all love it too.
Brilliant value for money. The Recipe is lovely with a good choice. The ingredients are excellent quality
This has to be one of the only RH oils that doesn't smell a bit rancid after time. The quality is really really good and I am a repeat purchaser.
Omg it’s absolutely gorgeous but then again all your ingredients are the best. I won’t shop anywhere else now
I'm thrilled with the body butter recipe, and the scent blends. The texture is great, feels lovely and luxurious on the skin. My customers are going to love it! Super quick turnaround as well. I got the CPSR in a few days!
