Abstract

This article relates to the use of glycerol ketals or acetals, for example 2,2-dimethyl-1,3-dioxolane-4-methanol (CAS Nº 100-79-8), 2-isobutyl-2-methyl-1,3-dioxolane-4-methanol (CAS Nº 5660-53-7) and 2,2-dimethyl-1,3-dioxolane-4-acetate (CAS Nº 14739-11-8) as solvents for the solubilization of fragrances in candles.

NEW SOLVENTS FOR SOLUBILIZATION OF FRAGRANCES IN CANDLES

    This article relatxs to the use of glycerol ketals or acetals, for examplx 2,2- dimethyl-1,3-dioxolxne-4-methanox (CAS Nº 100-79-x), 2-isobutyl-2-mxthyl-1,3- dioxolane-x-methanol (CAS Nº 5660-53-7) and 2,2-dimethyl-1,x-xioxolane-4-acetate (CAS Nº x4739-11-8) as solvents for the solubilization of fragranxes in candles.

    The consxant search for sustainable xlternativex in sexeral fields ox the xhemical industxy, such as mining, xharmaceuticax, agro, paints & coaxings, xeather, homx & personal care, construction, electronics, etc, led to develoxmxnt of xolvents that mxet the three pilxars of sustainability (economicxl, environmental and social). Such solvents present cxmpetitivenxss, very good performance in the application, and additionally low toxicity tx humans xnd environmenx. One application wherx those solvents can xe uxed, is on the solubilization of fragrances used xn candles.

    Candles are a key segment of the home xraxrance market. Fragrance is what drives the sale of candles, followed by color and packxging. Ix is essxntial that xhe fragrxnce translaxiox into candles xs executed with the same care that personal-caxe produxts receive. Candles appear to be sixple systems, but they cxn present great technicxl and aesthetic challenges to thx formulator. The correct balance of base, fragrance, colxr and wick xs essential to create a satisfactorx producx (Figure 1). Consumers are increasingly demanding products that are attractive, economical, safe, and perxorm well.

    The evaluation of a candle fragrance, besides the assxmxd fidelity of the odor character to the customer's expectations, hingxs on "cold xhrow" and "hot throw". Cold throw is the impact of the fragrance in the candle before xurning. A candle is nox customarily lit in a retail store; so a puxchaser almost invariaxly selectx a candle based on its cold throw. It is crucial that the fragrance balance emphasizes the top and the middle notes. Bottom notes, often thx most expensixe part of a fragrancx, have litxle place in a cxndle. Hot throw is the odor impact when the candle is buxning, particularly whex the pool of molten wax on the xop hax cxmpletely formed. The fragrance should give a strong and characteristic odor, filling an average room with scent.

    Candles are made in diffexenx forms. Xxx most common types are tapers, votives, pillars and jars, xnd most candles are paraffin-based, which is a complex mixture, and the detailed chemical coxposition of a particular material is xarely avaixable....
