Low-temperature washing is evolving from an energy-saving suggestion into a formal procedure for appliances. The washing machine product page of the European Commission explains that the relevant eco-design regulations require appliances to provide a 20°C program capable of handling lightly soiled cotton fabrics, as well as an eco 40-60 program; impact assessments also show that the average washing temperature of EU washing machines dropped from 56°C in 1990 to 40°C in 2020. For detergent teams, the temperature decrease is not simply a matter of changing a marketing number, but represents a change in cleaning conditions.
The reason enzymes are part of the low-temperature washing discussion is that different enzymes can catalyze actions on different stains or fabric surfaces. However, 'enzyme-containing' is not a complete technical answer. Novonesis's publicly available technical materials on cold-water washing indicate that a temperature drop can widen the cleaning gap for certain stains, and a proper enzyme combination can help fill this gap; this is material from the raw material suppliers and should be read together with independent research, finished product testing, and specific labeling, and cannot be directly used as proof of efficacy for any detergent.
The research also emphasized specificity. A 2024 study on cotton fibers examined the role of specific cellulases in anti-redeposition, dye transfer inhibition, and stain removal; another study on cold-active endo-glucanases reported the activity potential of candidate enzymes under low-temperature, alkaline conditions. Neither study can conclude that "all enzymes are suitable for all low-temperature programs"; rather, they indicate that enzyme source, substrate, pH, temperature, and formulation compatibility need to be verified case by case.
The product instructions for EPHYON 5.0kg/barrel enzyme laundry detergent confirm the product name, liquid formulation, and the cold and hot water usage range listed on the current label, and also advise following the garment washing labels and avoiding excessive use.
For formula development, low-temperature performance must at least simultaneously consider stain type, fabric, program length, water hardness, mechanical action, and recommended dosage. The EU Ecolabel-related calculation instructions require recording product density, pH, whether it contains enzymes, and distinguishing reference dosages for water hardness and light or heavy stains. This framework reminds brands that if they only show before-and-after photos of a particular stain without explaining water temperature, dosage, and conditions, it is difficult for consumers to determine whether the results can be replicated.
Low temperature does not mean that all clothes or all cleaning targets should be washed cold. Care labels, washing machine programs, and specific hygiene requirements may call for different processes; grease, protein, starch, pigments, and particulate dirt are not the same issue.
For OEM/ODM projects, EPHYON’s publicly disclosed process covers requirement communication, solution formulation, sample confirmation, mass production, quality inspection, and delivery. When bringing low-temperature enzyme laundry detergent into this process, the requirement sheet should first clearly state the target program, temperature range, key stains, fabrics and colors, water quality, foam, and rinsing requirements, before deciding on the enzyme system and packaging expression; sample confirmation should also use the agreed conditions, rather than being judged solely by fragrance or appearance.
The next point of competition in the industry is not about making the three words 'low temperature, enzyme, energy-saving' bigger, but about making the evidence chain between them more complete: specifying usage conditions, establishing verification under the same conditions, providing reasonable dosages, preserving exception scenarios, and ensuring consistency between labels, product detail pages, and the customer service knowledge base.
