I am preparing to take my final exam in the cosmetic chemistry degree program at the Institute of Personal Care Science.
Each and every class along the way has been as challenging as any of my university couses taken on my way to obtain my BSc.
I was able to work at my own pace and all the tutors were very helpful. Tasmin, Marica and Diane were always helpful as I sometimes struggled with concepts. The lectures by Belinda were brilliant. I was able to watch and learn as many times as needed as she guided me through the program.
Belinda also designed the Create cosmetics program. I highly recommend that every cosmetic and skincare DIYer get a yearly subscription as it is affordable and will save you hundreds of dollars in mistakes.
I highly recommend the degree program over the independent study (you can upgrade). Feedback from a qualified cosmetic chemist is invaluable.

Although some sodium hyaluronate can thicken a product, it is not a stable rheology modifier. Choose a gum or polymer instead for long term stability.

It sounds like you want to learn advanced cosmetic chemistry techniques. You should take Perrys course on Beginning Cosmetic Formulation. I would suggest you also enroll at the Institute of Personal Care Science. I have finished the program here but Belinda courses and chemistry degree program will give you the foundational skills to competently formulate from scratch for companies and always get good results.
2 in 1 products really only work for people with short hair who shampoo frequently. Compare your product to the leading brand out there. Note: most consumers love bubbles and judge effective cleaning by the bubbles, your target market may be limited.

From the information you have provided it sounds like you should be using a build with more lipids with more spread (emollient esters, silicones). If you have a lot of powders you need to also look at your stabilizers (gums, polymers).
Since you are a beginner, I would contact the pigment supplier and see if they have any sample formulas to begin your foundational work if you do not want to take courses.

From my historical research on vanishing creams, the main ingredient is not oil but stearic acid. Sodium stearate is formed during processing using a strong alkali. The Indian brand Vicco Turmeric and older Ponds formulations use this method. It is intended for oily skin type and ‘vanishes’ unlike oil based creams. It should have a naturally pearlized look due to the high ratios of stearic acid. <div>
Your formulation is more of a o/w cream and the lipids you have chosen are the most likely reason for the skin feel. Humectants also add tack so perhaps you would improve the sensory feel by reducing the glycerin.
