Color Fastness to Saliva in Baby Textiles
The color fastness of textiles used in baby products is a critical aspect of ensuring their safety and quality. This test evaluates the resistance of dyed or pigmented fabrics to the acidic environment found in saliva, which can potentially cause harmful dyes or chemicals to leach out onto skin. This service ensures that any materials coming into contact with an infant’s delicate skin do not pose health risks.
According to ISO 105-D02, this test method is designed for assessing the resistance of dyed and printed textile materials to extraction by a synthetic saliva containing hydrochloric acid. The process simulates the conditions that might occur during actual use or accidental contact with the infant's mouth.
The testing procedure involves placing a small specimen in direct contact with an appropriate amount of synthetic saliva, which is then agitated for a specified period under controlled conditions. After extraction, the specimen is thoroughly rinsed and dried before analysis by colorimetric methods to measure any changes in color intensity or hue.
Quality managers and compliance officers rely on this test to ensure that all textiles used in baby products meet strict safety standards set forth by regulatory bodies such as ASTM F1675-03(2018). This standard specifies the requirements for determining whether textile fibers will release potentially harmful substances when exposed to saliva. By adhering to these guidelines, companies can minimize risks associated with chemical exposure during product use.
R&D engineers may also benefit from this service by gaining insights into how different dye types or printing techniques affect colorfastness performance under real-world conditions. This information helps them develop more durable and safe products while optimizing production processes to meet market demands without compromising on quality.
Procurement teams can use the results of these tests as part of their supplier evaluation criteria to identify reliable partners who consistently deliver high-quality materials that pass rigorous safety checks. Ensuring consistent compliance with international standards like ISO 105-D02 strengthens brand reputation and builds consumer trust in baby care products.

Why It Matters
The importance of color fastness to saliva cannot be overstated when it comes to baby textiles. Babies often chew or suck on their clothing, which could lead to ingestion of harmful chemicals if the material isn’t properly treated and tested.
- Reduces the risk of ingesting potentially toxic substances from dyed fabrics.
- Promotes longer-lasting product durability by ensuring that colors remain vibrant even after repeated washings.
- Enhances consumer confidence in your brand’s commitment to safety and quality.
Applied Standards
The primary standard used for this service is ISO 105-D02. This international standard provides detailed instructions on how to conduct the test, including sample preparation, synthetic saliva composition, agitation conditions, and measurement techniques.
ASTM F1675-03(2018) further supports these guidelines by specifying additional criteria related to the types of textiles that should undergo this particular test. Both standards emphasize the importance of accurate testing procedures in order to provide reliable data on colorfastness performance.
