In the cosmetics industry, especially in the field of detergent production, pH is one of the most important factors that directly affects the cleaning efficiency and the ability to protect fabric fibers. Not only does it help remove stains effectively, pH also determines the durability, color and softness of clothes after each wash. Understanding the […]
What is pH and its role in laundry detergent?
pH is an index that measures the acidity or alkalinity of a solution, ranging from 0 to 14. A pH value of 7 is considered neutral, less than 7 is acidic, greater than 7 is alkaline. In laundry detergent, pH affects the ability to dissolve and decompose stains such as grease and dirt, and also affects the structure and durability of fabric fibers.
If the pH is too high (strong alkaline): The detergent can clean quickly but can easily cause the fabric fibers to fray, fade, and reduce the life of the clothes.
If the pH is too low (acidic): The cleaning ability is reduced, stubborn stains cannot be removed, and clothes are prone to bacteria and mold accumulation.
Balanced pH (near neutral): Cleans effectively, protects color and softness, and maintains the fabric fiber structure.
The effect of pH on fabric color and durability
pH not only affects the cleaning ability but also determines the color fastness and quality of the fabric. A detergent with the right pH will maximize the cleaning ability without damaging the fabric.
High pH laundry detergent: Easily fades colors, makes clothes wear out quickly, fabric fibers become stiff, and lose their original beauty.
Low pH laundry detergent: Good color retention but poor cleaning effect, easy to cause bacteria accumulation and odor.
pH balanced laundry detergent: Keeps clothes fresh, colors long lasting and fabric soft through many washes.
Especially for children’s clothes or people with sensitive skin, choosing a detergent with balanced pH is a prerequisite to protect the skin from irritants.
Not only affecting cleaning ability, the effect of pH is also evident in protecting the color and quality of fabric fibers.
High pH detergent: Easily fades colors, makes clothes quickly wear out, fray, and lose their original beauty.
Low pH detergent: May preserve color but does not clean effectively, causing clothes to accumulate bacteria and mold.
pH balanced laundry detergent: Deep cleans while protecting colors, keeping clothes fresh and beautiful through many washes.
During the washing process, detergents often create a highly alkaline environment (pH from 12-13) to help the fabric fibers expand and effectively separate stains. However, keeping the pH at a high level after washing will damage the fabric structure, reduce the life of the clothes and can cause skin irritation.
Therefore, the pH neutralization step after washing is very necessary to bring the pH environment to a safe level (about 5.5 – 7), helping to protect the fabric fibers and the user’s skin. This also helps reduce the number of rinsing steps, saving time and energy.
Therefore, we need to choose detergent with suitable pH:
Prioritize laundry detergent with a near-neutral pH (around 7): This is the ideal pH level that helps balance cleaning efficiency and fabric protection.
Avoid products with pH that is too high or too low: Especially with children’s clothing, underwear, or high-end fabrics, as they can easily damage and irritate the skin.
Choose products from reputable brands: Large manufacturers like THT often strictly control the pH in their formulas, ensuring safety and effectiveness.
