Home Cosmetic Science Talk Formulating Stable cream base

  • Stable cream base

    Posted by AZIZ_KALUNGI256 on November 14, 2021 at 5:59 pm

    Hi esteemed chemists here, i have made an experimental cream using this base, its thick and smooth in texture. But am worried if the PEG 75 LANOLIN may be comedogenic and lead to breakouts. I welcome views and suggested swaps, ommissions or adjustments on any of the ingredients. 
    Thanx .
    Cetyl alchol 2%
    Glycerol mono  steatate (GMS) 3%
    Stearic acid 3%
    PEG 75 LANOLIN  0.5%
    Glycerin 3%
    Propylene glyco 1%
    Triethanolamine (TEA) 0.2%
    Mineral oil/ liquidum paraffinum 3%
    Petrolatum or micro wax 1%
    Distilled water 82.3% ( or less by the percentage of actives i will use later)
    Polyxethanol 1%

    Maybe at 100%. But at 0.5% not

    Preservative is not enough. And i think you don’t have emulsifier

    @AZIZ_KALUNGI256 Not sure 0.2% of TEA would be enough to neutralize Stearic acid to make it work as emulsifier. Also, phenoxyethanol is not a broad spectrum preservative (you might want to add Sodium benzoate, and EDTA to boost your preservative system).
