Description

Technical Field

[0001] This invention relates to the field of daily chemical product technology, and to a carrier-based fragrance-retaining product and its preparation method. Background Technology

[0002] Laundry fragrance beads, as a product containing slow-release fragrance ingredients, apply microcapsule fragrance to clothing during the washing process. When people wear the clothes, the microcapsules break due to the friction between the skin and the fabric fibers, thus slowly releasing the fragrance components and achieving the function of long-lasting fragrance on the clothes. They are becoming increasingly popular and are gradually becoming a functional product that partially replaces perfume fragrances.

[0003] Existing fragrance bead formulas generally contain polyethylene glycol, starch, silica, fragrance, and microcapsule fragrance as the main components. Polyethylene glycol serves as the main carrier, starch and silica as fillers, and fragrance and microcapsule fragrance are the core components for fragrance retention.

[0004] In addition, existing fragrance beads often contain softening agents. Softening agents have two drawbacks: they usually affect the dissolution of the fragrance beads and have limited softening effect. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a carrier-based fragrance product that uses polyester compounds as the main carrier, thereby achieving a more stable and longer-lasting fragrance control and release effect than traditional fragrance beads and liquids, while also providing excellent smoothing properties.

[0006] The present invention provides a carrier-based fragrance product, which includes a carrier and a fragrance component, wherein the carrier includes a polyester compound.

[0007] In one embodiment, the polyester compound is a moisture-wicking finishing agent.

[0008] Conventional moisture-wicking finishing agents are viscous liquids, soluble in water at room temperature, and possess excellent hydrophilic and softening properties. When the fragrance components contain microcapsule fragrances, using the moisture-wicking finishing agent as a carrier allows it to synergize with the capsule components in the microcapsule fragrance, achieving a more stable and longer-lasting fragrance control and release effect than traditional microcapsule fragrances. Furthermore, the moisture-wicking finishing agent itself has a hydrophilic and softening effect, especially on polyester and polyester blended fabrics. Therefore, the fragrance product in this case not only has excellent fragrance retention but also excellent hydrophilic, softening, and antistatic properties.

[0009] In one embodiment, the moisture-wicking finishing agent is selected from at least one of Derby® DP-998B and Comfort® DP-2005.

[0010] In one embodiment, the fragrance component includes fragrance and / or microcapsule fragrance.

[0011] In one embodiment, when the fragrance product is a fragrance bead, the carrier comprises a polyester compound or the carrier comprises a polyester compound and polyethylene glycol; The fragrance-retaining product also includes additives, including fillers, which include starch and / or silica. The fragrance beads comprise the following raw materials in the indicated weight ratios:

[0012] When the weight percentage of polyethylene glycol is 0, the fragrance retention effect of the fragrance beads is better, but the dissolution rate is slower and the dissolution time is longer. Given different washing needs, there are different requirements for the dissolution rate and fragrance retention effect of the fragrance beads. Therefore, the amount of polyethylene glycol used can be selected according to the customer's washing requirements. Combining polyester compounds with an appropriate amount of polyethylene glycol can adjust the viscosity of the fragrance bead material.

[0013] Starch and fumed silica are used as fillers in fragrance bead formulations, mainly to maintain a good appearance and low cost. The dosage can be set to 0 depending on product requirements.

[0014] In one embodiment, the number-average molecular weight of the polyethylene glycol is 1,000-10,000.

[0015] In one embodiment, the polyethylene glycol comprises the following raw materials in parts by weight:

[0016] In one embodiment, the fragrance beads comprise the following raw materials in parts by weight:

[0017] In one embodiment, the fragrance beads further include pigments, and the fragrance beads comprise the following raw materials in parts by weight:

[0018] Understandably, the types and amounts of the pigments and flavorings mentioned above are added according to product requirements.

[0019] In one embodiment, when the fragrance product is a fragrance liquid, the carrier includes a polyester compound; The fragrance-retaining product also includes additives, including preservatives; The fragrance liquid comprises the following raw materials in the indicated weight ratios:

[0020] The aforementioned fragrance liquid, while possessing excellent fragrance retention, anti-static, and smoothing effects, can also reduce the addition of other components, thereby increasing the proportion of effective ingredients in the overall fragrance liquid and making the preparation of the fragrance liquid more economical and efficient.

[0021] In one embodiment, the flavor component comprises the following raw materials in parts by weight:

[0022] In one embodiment, the fragrance liquid further includes macromolecular dyes, and the fragrance liquid comprises the following raw materials in parts by weight:

[0023] The present invention also provides a method for preparing the aforementioned fragrance product, wherein the fragrance product is a fragrance bead, and the preparation method includes the following steps: heating and melting the carrier, stirring, adding an auxiliary agent, stirring, adding a fragrance component, stirring, granulating, and obtaining fragrance beads.

[0024] In one embodiment, when the fragrance product is a fragrance bead, the preparation method includes the following steps: heating and melting polyester compound and polyethylene glycol at 60-100°C and stirring evenly, adding starch and fumed silica, stirring evenly, adding fragrance components, stirring evenly, granulating, and obtaining fragrance beads.

[0025] The present invention also provides a method for preparing the aforementioned fragrance product, wherein the fragrance product is a fragrance liquid, and the preparation method includes the following steps: mixing a carrier and water, stirring, heating to dissolve and disperse the carrier, cooling, adding fragrance components and additives, stirring, and obtaining a fragrance liquid.

[0026] In one embodiment, when the fragrance product is a fragrance liquid, the preparation method includes the following steps: mixing a polyester compound and water, heating to 80-90°C under stirring conditions to dissolve and disperse the polyester compound, cooling to below 50°C, adding fragrance components and additives, stirring evenly to obtain a fragrance liquid.
