sos change of color
I would really appreciate it if you could give any advice about a production issue that I came across.
A simple recipe of a concealer stick, with carnauba wax, beeswax,ozokerite, paraffinum liquidum,castor oil, and pigments pre-despersed in castor oil.
we unfortunately 3 months after the production, have complains that the color looks beige, but it relly writes like pink.
I assume that we have oxidation, even if I used BHT and tocopherol..
Any advice would be appreciated.
