Production Application Case of High-End Toothpaste
A well-known daily chemical brand in Guangzhou focuses on high-end functional toothpaste (whitening, desensitizing, and gum-protecting), positioning itself in the mid-to-high-end consumer market. Its core demands are "delicate and sand-free paste, dense foam, uniform dispersion of active ingredients, no easy stratification, and mild taste without irritation".
The toothpaste produced by the enterprise's original equipment had problems such as rough and sandy paste, uneven dispersion of fluoride and whitening ingredients, rough foam, easy bubble generation during production, easy stratification of paste, and short shelf life, which could not meet the quality positioning of high-end toothpaste and led to poor market feedback.
To address the core pain points in toothpaste production, Guangzhou Yuxiang customized a linkage solution of RHJ series 500L special vacuum homogeneous emulsifier for toothpaste + constant temperature mixing tank, accurately adapting to the production needs of toothpaste paste (medium viscosity, multi-component mixing).
All parts of the equipment in contact with materials are made of 316L food-grade stainless steel, with mirror-polished inner walls and no hygienic dead corners, fully complying with food-grade production standards and toothpaste GMP requirements; the vacuum degree can reach -0.096MPa, and emulsification and mixing are carried out under negative pressure throughout the whole process, effectively eliminating bubble generation during production and ensuring the toothpaste paste is delicate and compact without holes or stratification.
In terms of core configuration, a combined structure of frequency conversion speed-regulating high-shear emulsifying head and scraper mixing is adopted, with the rotating speed accurately adjustable between 500-8000rpm.
It can not only refine raw materials such as fluoride, whitening factors and abrasives to the micron level to achieve uniform dispersion and avoid sandy paste, but also realize dead-corner-free mixing through scraper stirring to ensure uniform ingredients everywhere in the toothpaste; the jacketed constant temperature control system has a temperature control accuracy of ±0.5℃, which can accurately control the emulsification temperature at 35-45℃, avoiding the loss of active ingredients and paste deterioration caused by high temperature, and at the same time helping the perfect integration of various components of toothpaste to improve foam density.
In addition, the equipment is equipped with a PLC intelligent control system, which can store 60 sets of toothpaste formula parameters, support one-click call, quickly switch the production of different functional toothpastes such as whitening, desensitizing and gum-protecting, adapt to the needs of mass and multi-category production.
At the same time, it is equipped with a quick-detachable cleaning structure, which is convenient to clean and avoids cross-contamination of different formulas.
After the equipment was put into use, the quality of the high-end toothpaste produced by the customer was significantly improved: the paste is delicate and smooth, without sand feeling or bubbles, the foam is dense and easy to rinse, and the taste is mild without irritation; the active ingredients such as fluoride and whitening agents are evenly distributed, the stability of efficacy is greatly improved, and the whitening and desensitizing effects are significantly enhanced; the paste forms stably, with no stratification or precipitation during long-term storage, and the shelf life is extended to 2 years.
The single-batch production capacity of the production line is increased by 40%, the product qualification rate is increased to 99.8%, and the rework rate is decreased by 92%, helping the customer successfully seize the high-end toothpaste market. The products have settled in major high-end supermarkets and online flagship stores, the market share has continued to increase, and the brand reputation has been further consolidated.
