test procedure
Sample
A model formulation of liquid kitchen detergent with the following composition was used as the measurement sample.
mass%
Nonionic surfactant : 6 (active ingredient)
SANDET END *1 : 11 (active ingredient)
PROFAN 128 EXTRA *2 : 0.4
water : Remaining amount
--------------------------------------------------------------
Total :100mass%
*1: Our product, sodium salt of alkyl ether sulfate
*2: Coconut oil fatty acid diethanolamide
Method of measuring cleaning power
The cleaning power was measured according to the Lee-Nut method (JIS K 3370). However, six glass slides were used as a set of stain support, and a chloroform solution of artificial stain of the following composition was applied to the stain component. A 0.15 mass% aqueous dilution of the sample concentration (active ingredient) was used as the cleaning solution, and the supports coated with the artificial stain were cleaned using a Lehnhardt modified method tester to obtain the cleaning power from the following formula.
Artificial stain
Artificial stain was made by dissolving 20 g of a mixture of beef tallow and soybean oil at a volume ratio of 1:1, 0.25 g of monoolein, and 0.1 g of oil red in 60 ml of chloroform.
Washing power
Cleaning power = (amount of stain before cleaning g - amount of stain after cleaning g) × 100 / amount of stain before cleaning g
Viscosity Measurement Method
The viscosity of the sample was measured at 30°C using a B-type viscometer.
Low Temperature Stability Measurement Method
After the sample was left at -5°C for 24 hours, its appearance was visually observed and judged according to the following criteria.
good: Clear liquid
poor: Cloudy
In addition to surfactants, detergents may contain appropriate foam stabilizers, solubilizers, and builders. Please check the performance, safety, and stability of these formulations in advance.
EMULMIN FL, HL" series are non-ionic surfactants. Therefore, if they are used together with sodium hypochlorite in bleach applications, sodium hypochlorite will decompose and the oxidizing effect of sodium hypochlorite will oxidize "EMULMIN FL, HL" series, causing performance degradation. Therefore, do not use with sodium hypochlorite bleaches.
Please be sure to read the "Safety Data Sheet" (SDS) for each product and sub-material (chemical) before handling the products listed on this website. The SDS can be obtained from here. https://www.sanyo-chemical.co.jp/products/en/sds/
