The shelf life of cleaning and care products is not arbitrarily set, but a reasonable period obtained through scientific testing and evaluation based on various factors such as product raw material characteristics, production processes, packaging methods, and storage conditions. Accurately determining the shelf life can not only ensure the stability and safety of product performance within the validity period, but also avoid resource waste or safety hazards caused by improper setting of the shelf life. It is a key link in the processing of washing and care products.
1、 The characteristics of raw materials and formula stability are the fundamental basis
The characteristics of product raw materials and the overall stability of the formula are the core basis for determining the shelf life. The chemical properties of different raw materials vary greatly, and some active ingredients are prone to oxidation, hydrolysis, or degradation, which affects product performance and safety. During the outsourcing process, it is necessary to evaluate the shelf life, storage conditions, and chemical stability of the raw materials, and prioritize the selection of materials with strong stability. At the same time, through compatibility testing of the formula, analyze whether there is any interaction between the components that may cause deterioration, such as the combination of certain preservatives and active ingredients that may affect the anti-corrosion effect, thereby shortening the product shelf life. The pH value, viscosity, and other parameters of the formula should also be controlled within a reasonable range to ensure that the product is not easily stratified or deteriorated during storage, providing basic data support for shelf life setting.

2、 Production process and quality control affect the upper limit of shelf life
Standardized production processes and strict quality control can effectively extend the shelf life of products. During the outsourcing process, the cleanliness of the production environment is crucial to avoid microbial contamination in the production process, such as using aseptic filling technology, controlling the temperature, humidity, and air cleanliness of the production workshop. The process steps of raw material mixing, heating, cooling, etc. must strictly follow the standard procedures to prevent the denaturation of raw materials or the production of harmful substances due to improper processes. At the same time, establish a comprehensive quality inspection system to test the microbiological indicators and physicochemical properties of products during the production process and before leaving the factory, ensuring that the initial quality of the products meets the standards. The standardization of production processes directly determines the initial state of the product, which in turn affects the upper limit of the shelf life.

3、 Packaging materials and sealing performance ensure stable shelf life
The selection and sealing performance of packaging materials are important guarantees for maintaining product quality stability during the shelf life. Washing and care products often contain moisture and active ingredients, which can easily deteriorate due to external factors such as oxygen, light, and microorganisms. Choose packaging materials with strong barrier properties based on product characteristics, such as oxygen and light blocking plastic bottles or aluminum foil bags, to reduce the impact of external environment on the product. At the same time, the sealing performance of the packaging must meet the standard to prevent leakage, moisture absorption, or microbial invasion during storage and transportation of the product. Some products will also adopt vacuum packaging or press type bottle mouth design to further isolate air and pollutants, delay product deterioration rate, and provide physical protection for stable shelf life.
In short, the determination of the shelf life of laundry care products requires a comprehensive consideration of various factors such as raw materials, processes, and packaging. In the cooperation of contract manufacturing, the brand owner and the contract manufacturing factory need to closely cooperate and jointly participate in the evaluation and determination process of shelf life to ensure that the shelf life is set scientifically and reasonably. Accurate shelf life is not only a guarantee of product quality and safety, but also a manifestation of brand responsibility to consumers, which helps to enhance brand credibility and promote the healthy circulation of products in the market.
