Following recipe gives a too soft view after creating and seems unstable: salicylic acid 5gr tween 60 5gr ung aquosum, Aqua PBV ad 100gr FAC unguentum

The usefulness of the tween is not very clear to me, mainly because non-ionogenic Tensio-active compounds are more susceptible to salicylic acid as after lauryl sulfate, which is also not completely insensitive to salicylic acid but still much less than e.g. Tween.

increase the amount of Lanette N to 15 g in the Ung aquosum. I would prefer not to leave the Tween out of the composition that might have an impact as a "absorption promoter". The correction gives the CR è me a nice view with good consistency.

response:
This preparation yielded problems regarding consistency and view. By the increase of Lanette N to 15 GR, as recommended by you, this preparation does not deliver any problem anymore. The CR è me has good consistency and a nice view. Prof. Kinget Thank you for your advice!
