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!

Using Liquid Ingredients? Here’s What Comes Next
If you’re planning to sell your product, your final formulation must meet UK cosmetic regulations and be fully documented. All of our liquid cosmetic ingredients are compliant, but when you create a new cosmetic product, you need to ensure your final formulation meets regulatory requirements.
As cosmetic safety assessors, we know how compliance connects to formulation. Whether you are working with humectants like glycerine, botanical extracts, or ingredients used in hair care and leave-on products, each component must be properly documented.
We work with you to identify issues early on, helping you avoid potential delays and go to market faster.
What happens next:
- We review your recipe and all ingredients included in your formulation
- We check the documentation and identify anything missing
- We tell you if any changes are needed before completing your CPSR
- We provide a clear, no-obligation quote for your CPSR
There is no obligation to proceed, no consultancy fee, and no hidden costs. We are always upfront with our pricing to give you peace of mind. Contact us when you are ready to discuss your requirements.
Liquid Ingredients FAQs
Do I need a CPSR when using liquid cosmetic ingredients?
If you are selling a finished cosmetic product, it must have a CPSR before it can be placed on the market.
Are all liquid cosmetic ingredients the same quality?
No. Ingredient quality and documentation can vary significantly between suppliers. Using poorly documented or inconsistent ingredients can lead to delays, changes in the performance of your product, or issues during the CPSR process.
Are your liquid ingredients supplied with documentation?
Yes, all ingredients are supplied with relevant documentation, including SDS and supporting information required for cosmetic safety assessments.
How do I choose the right liquid ingredient for my skincare products?
The right choice depends on your product type, target market, and formulation goals. For example, Phytokeratin is popular for haircare, while hydrosols for skincare are commonly used in toners and mists.
Can I mix different liquid ingredients together safely?
Yes, but compatibility and safety must be assessed. It is important to carry out your own small batch testing to confirm the stability and performance of your product, its suitability for the intended use of the finished product, and that the appearance aligns with your goals.
