Due to negative customer opinion it looks like I will have to remove parabens from our creams. I have been using Spectrastat by Inolex for quite a while at the minimum recommended level (0.7%) in our gels, which are oil-free, with no problems. Shelf life is at least 6 months. Spectrastat (caprylhydroxamic acid and caprylyl glycol and glycerin) is an attractive option because it technically is preservative-free.
This is a shout for HELP! because I never expected so many options.
My options are: 1-5 "blended systems for ease of use"
1. Lexgard HPO (caprylyl glycol and hexylene glycol and phenoxyethanol) "paraben free"
2. Lexgard OE 90 (caprylyl glycol and ethylhexylglycerine) "preservative free"
3. Lexgard NAP (caprylyl glycol and phenethyl alcohol) "preservative free"
4. Lexgard GCP (glyceryl caprylate and phenethyl alcohol) "preservative free"
5. Lexgard Natural (glyceryl caprylate and glyceryl undecylenate) "preservative free"
6-8 "optimized systems providing robust, broad spectrum activity" all "preservative free" except Spectragard which is "paraben free"
6. Spectrastat (caprylhydroxamic acid and caprylyl glycol and glycerine)
7. Spectrastat G (caprylhydroxamic acid and glyceryl caprylate and methylpropanediol)
8. Spectragard (added only at <50C) (caprylyl glycol and hexylene glycol and methylisothiazolinone)
"budget systems supplying affordable broad-spectrum activity"
9. Phenostat (caprylhydroxamic acid and phenoxyethanol and methylpropanediol) "paraben free"
10. Benzostat (caprylhydroxamic acid and benzyl alcohol and glycerine) "paraben free"
11. Aromastat (caprylhydroxamic acid and phenethyl alcohol and glycerine) "preservative free"
12. Zeastat (caprylhydroxamic acid and propanediol) "preservative free"
