Information on hygiene guidance for household goods

Last Updated October 3, 2023

About hygiene of household goods

This is the site of Health Sanitation Division, Health and Safety Department, Yokohama City Public Health Center. We provide information on the hygiene of household goods.

In order to prevent health hazards caused by household goods such as baby clothes and underwear, household goods such as laundry detergents and aerosol products, the Health Sanitation Division Department of Health and Safety at Health Centers conducts inspections of household goods from dealers in the city. In addition, as a result of inspection, we provide guidance such as discontinuation of sales of products that violate the standards.

Safety measures and responsibilities carried out by manufacturers and importers

Safety measures and responsibilities carried out by manufacturers and importers

Manufacturers and importers must pay the best attention to ensuring the safety of their products. For example, product inspection must be carried out actively using our own inspection department or various inspection organizations.
In addition, organize and store shipping slips, etc. that describe the shipping destination, product type, number, etc.

Preliminary check when manufacturing and importing products

When manufacturing and importing products, check whether they are subject to regulation.

[Check raw materials and imported goods]

In the case of regulated products, we will check whether raw materials or imported products contain no harmful substances and how much they are contained. For cleaning agents, test the strength of the container.
※Storage of Inspection Reports

[Check the manufacturing process]

Enhance quality control and ensure that hazardous substances are not mixed in the manufacturing process.

[Check the finished product]

Once the product is completed, the content of hazardous substances is tested.
※Storage of Inspection Reports

[Check for packing and storage]

Store products in a well-organized and appropriate manner to prevent contamination from unregulated products and sources of harmful substances, and be careful not to mix harmful substances when attaching tags, packing, transporting, etc.

[Check long-term storage items]

In particular, check the quality again before shipping long-term storage items.

Safety measures and responsibilities implemented by wholesalers

Safety measures and responsibilities implemented by wholesalers

Sellers must pay close attention to purchasing safe products, proper storage and management, and how they are sold to consumers. In addition, purchase and sales slips that describe the type and number of products should be organized and stored.

[Check when purchasing]

When purchasing products, confirm with an inspection certificate that no harmful substances are contained. When verifying the inspection certificate, make a copy or record and save it.
※Confirmation and record of inspection report

[Check for packing and storage]

Store products in an appropriate and organized manner to prevent contamination from unregulated products and sources of harmful substances, and be careful not to mix harmful substances when attaching tags, packing, transporting, etc.

Prevent contamination from unregulated products and source of harmful substances by paying attention to the storage of properly organized products and sales methods at stores.
As for cleaning agents, the container deteriorates depending on the method of storage and display, so be careful when handling. Also, in consideration of disasters, etc., let's display them in low places.

About the transfer of formaldehyde

About the transfer of formaldehyde

Formaldehyde is easily soluble in water, so it is easily absorbed into fibers through moisture in the air. For this reason, if the source of formaldehyde is nearby, it may be transferred to clothing.
This phenomenon is called the transfer of formaldehyde.

Source of formaldehyde

The sources of formaldehyde are as follows.

Building materials
Plywood, structural plywood, synthetic resin sheets, heat insulating materials, adhesives, etc.

Fibers
Non-regulated textile products (such as shirts, blouses, etc.)

Others
Furniture, cigarette smoke, cardboard, wax, exhaust gas, etc.

In particular, clothing for infants who do not use formaldehyde must be kept away from these sources. Also, if the product is placed directly on a display stand using plywood, formaldehyde may be transferred.

What is more likely to be transferred?

Fibers that are susceptible to transfer.
Wool silk>Cotton>Rayon nylon>Polyester acrylic
In order.

Air concentration of formaldehyde in the store

The higher the temperature, the more likely it is to be released into the air from the source, so even at stores, when the temperature inside the store is high, such as during summer air-conditioning stop hours, the higher the concentration of the room air.
Pack your products as much as possible to prevent transfer.
