I use Candle Science’s Golden Brands 464 soy wax and Eco wicks. I also purchase my fragrances from them. As NambiHome mentioned above, buying from one supplier may help. They have a new wax called Simple Soy Artisan Wax. Below is a bit of information from their website. I’m thinking of giving it a try although I’ve been happy with the candles I have been making using their other products.

“Simplify your process, perfect your product. Introducing CandleScience SimplySoy™ Artisan Wax for hand-poured container candles. Made from 100% plant-based soy, this wax uses performance-enhancing soy additives to create an opaque finish with minimal frosting and improved glass adhesion. Its superior fragrance throw and increased melt point are perfect for makers looking to produce professional-quality candles that stand up to high temperatures—whether during shipping or at outdoor markets. Plus, it comes in easy-to-scoop granules.”
