A wax composition is disclosed, comprising a hydrogenated natural oil with (i) at least about 50 wt % of a triacylglycerol component having a fatty acid composition from about 14 to about 25 wt % C16:0 fatty acid, about 45 to about 60 wt % C18:1 fatty acid and about 20 to about 30 wt % C18:0 fatty acid, (ii) a nickel content of less than 1 ppm, and (iii) a melt point of about 49 C. to about 57 C. The hydrogenated natural oil is filtered and/or bleached to obtain a nickel content of less than 0.5 ppm. A candle is also disclosed, comprising a wick and the above described wax.

A customizable wax assembly comprising either interlocking Modular Candle Elements or a single-body Infuser-Compatible Candle structure, each configured to form three-dimensional candle assemblies. The Modular Candle Elements may define flat, angled, curved, or irregular outer profiles and are configured to engage with adjacent elements to form complete geometric, symbolic, or ornamental shapes, including but not limited to cylinders, hearts, pyramids, and other seasonally themed or user-customized configurations. One or more components may include cavities for receiving wicks and elongated Fragrance Elements positioned to extend from a Wick Zone inward or outward across a Thermally Active Zone, to promote early-stage and sustained fragrance release during combustion. Optional Assembly Keys may be incorporated to enhance structural stability and enable complex design patterns.

A multifunctional multi-layer candle includes a main body made of combustible material, a wick and a plurality of sleeve components removably sleeved on the main body. An upper end of the wick protrudes out from a top of the main body, and the rest part of the wick is embedded in the main body. The plurality of sleeve components can be sleeved on the main body in different sequences to form different shapes. The multifunctional multi-layer candle may be used as a children's splicing toy, a decorative ornament and a lighting. The sleeve components may be sleeved on the main body to form different candle shapes, which is beneficial for intellectual development, and the entire candle is more ornamental and funnier.
