  • Viscosity loss in final formula

    Posted by ESskincareLK on August 30, 2021 at 1:50 pm

    I am wondering what could be affecting the viscosity of my moisturizer formula. The base formula is great but the final formula is thinner than expected. The moisturizer is Hemp & Green Tea (marketing)

    up to 100% Distilled Water 
    2% Glycerin
    3% 1,3 Propanediol 
    3% Niacinamide 
    0.2% EDTA 

    3.5%  Glyceryl Stearate (and) PEG 100 Stearate 
    1.3%  Cetyl Alcohol 
    0.45% Sepinov EMT 10 
    0.1% P-Anisic Acid 
    0.05% BHT 
    6% Camellia Seed Oil 
    1.5% Tamanu Oil 
    6% Hemp Seed Oil 

    1% 1,3 Propanediol 
    0.9% Euxyl PE 9010 

    0.1% Rosemary Ole (may or may not be used for natural color also) 
    0.1% Bisabolol 
    1.5% Green Tea Extract (OS Scented Extract)  

    adjust pH to 5.2-5.5

    If I had to guess it is most likely the P-Anisic Acid or BHT since these are the most recent adjustments

    Any ideas or recommendations?

    Out of curiosity, from the list it looks like the P-Anisic Acid is in the oil phase and I was wondering why

    Good question! I guess just personal preference due to its lack of water solubility. Also I believe it was suggested in another discussion but I could be remembering wrong. It disperses / dissolves evenly in the emulsion. Maybe I will try adding it to the water phase to see if and what differences it makes. Thanks!
