This 2013 report is on the NGI-era wax; CandleScience's current chart lists only LX and ECO.6 Only one maker has reported this. Test it before you trust it. |

Problems makers report
Pastilles melt slowly
What makers do: Expect a longer melt time than with flakes.2
Frosting after months, worse on dark colors
What makers do: CandleScience saw none at 30 days and after burning, but very minor frosting at 6 months, more visible on dark colors. Frosting depends on fragrance and dye, so test your own mix.2
Read the fix: Frosting and Wet Spots in Candles: Causes and Fixes
Fragrance and dye change the burn
What makers do: LX gave even flames and little mushrooming in CandleScience's tests, but it warns dye and fragrance moved the results. Its 12 percent fragrance test showed no sweating, but it recommends no more than 9 percent.2
Pour and fragrance temperatures differ by seller
What makers do: CandleScience says pour at 150 F. A Canwax reviewer who switched from 464 added fragrance at 150 F and poured at 140 F and got good tops. Canwax lists a 135 F pour.15
Notes from the sources
- Status: not discontinued today and not renamed. NGI closed in 2019 and stopped the Q-series and CB-Advanced; Kerax bought the brand in early 2020 and sells the wax under the same name, in pastilles.15
- Kerax's data sheet gives a congealing point of 38 C (about 100 F), viscosity 8.5 cSt at 100 C and penetration 40 dmm. It gives no pour temperature or fragrance load and says every wax, wick, dye and fragrance combination must be burn tested.4
- Specs conflict. CandleScience's page says melt point 100 F, 10 percent container fragrance, two-week cure. Its lab notes say 6 to 9 percent recommended (12 percent showed no sweating) and at least three days of cure. Canwax says melt point 113 F, up to 10 percent (6 to 8 recommended), about a week of cure and HTP, LX or Premier wicks.125
- Three Canwax reviewers report smooth tops or no frosting. One switched from 464 and needed lower temperatures (fragrance at 150 F, pour at 140 F). They give no wick data.5
- Wood wicks: no EcoSoya wood wick chart was found. Makesy's wood wick article names no wax sizes.7
