Main Application
1. Water softener and buffering agent in detergent industry
2. Quality modifier, pH adjustment, water reserving agent and other functions in food industry
3. Paper making
4. Dispersing agent in oil drilling mud
5. Ceramic, mining, water treatment industry and etc.
Function in detergent industry:
STPP is a good auxiliary in detergent industry, the usual dosage is about 10~35%, the function of STPP in detergent system are:
1. Soften the hard water by reacting with metal ions of Ca2+, Mg2+, Fe3+ and others to make them from insoluble to soluble Na5P3O10+Ca2+ ---> Na3(CaP3O10)+2Na+
2. Enhancing the emulsifying and dispersing power, to increase the solubility of protein and dust which normally existing in the fabrics from daily life
3. Buffering agent, to make the pH value of detergent solution on the level of 9~9.5, so that those acid dirt can be easily removed from fabrics
4. Anti-caking agent for detergent powder. Since detergent powder is easily caking in exposed air, STPP can absorb the moisture and become Hexahydrate, which is dry and free flowing
Important Notice
1. About Phase 1 (Phase I) and Phase 2 (Phase II) - Phase 1 and Phase 2 are the same in chemical properties, they just have different crystal structure or crystal shape - STPP made from mass production is a mixture of both Phase 1 and Phase 2 - Different phase 1 or phase 2 content is related to different temperature and speed in production and hydration. The hydration of phase 1 is faster, release more heat during the hydration and easily get caked during the dissolving process. The relationship between the Phase I content and temperature rise of hydration is as below: Phase I content = 4 (T-6) T (Temperature rise) = T1 - T0 (T1 is the temperate after hydration, T0 is the temperature before hydration) So if the Phase I content is 27.6% 27.6 = 4 (T-6) T=12.9ºC(Means the temperatue rise is 12.9 ºC).
2. We normally list 2 years as the shelf life in our COA, the real shelf life is actually much longer than 2 years if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials).

Company Profile
LK (Nanjing) Co., Ltd. Is the initial member of the brand name RAWCHEM, established in 2008, served as the representative office of an European comprehensive trading company in its early years, mainly dealing with the import and export business of raw chemical materials for the detergent industry, now we have become an industrial company, focused on the detergent industry.

OUR BUSINESS MOTTO:
Everything for detergent, for detergent's everything.

Based on our business motto, according to the different type of our customers, our business is divided into 3 departments:
INDUSTRIAL BUSINESS
Industrial business is our traditional core business, our customers mainly are the local detergent brands, producers and distributors all over the world. Our main products are detergent-use raw chemicals like Sodium Sulphate (SSA), Disilicate (MSD), Soda ash, various surfactant products (AOS, SLES, SLS, LABSA, LAS, AEO...) and etc. Among these products, the disilicate series new type phos-free STPP replacement products are our strong and featured items, our exporting quantity is more than 60% of China's total export.
Our detergent-use raw chemicals are mainly originated in China mainland, but our sources are not limited to China only. To server our customers with more detergent-use raw chemical items, more competitive price and more multiple and stable supply chains, we are developing more and more overseas suppliers to fulfil our global customers' needs.
Our target on this is to become an organizer of the global resources related to the detergent industry.
Beside the detergent-use raw chemicals, we are dedicated in promoting China originated detergent-use production lines and racking systems to our global customers too.
As our business motto said, each and every need of our detergent industry customers, is the direction we are going to work out.
For this part of business, we do free consulting and designing, the production, installation and maintenance will be fulfilled by the related factories directly.
COMMERCIAL BUSINESS
Commercial business is our high-lighted new business department. Customers are mainly laundry shops, cleaning service contractors of public area and those factories with the special needs of equipment or products cleaning.
Based on our wide-scope detergent-use raw chemical items, stable supply chains and years of application experience, we are developing the customized cleaning products for our commercial customers according to their common requests of low price, high efficiency, safe and easy, environment friendly and etc.
CONSUMER BUSINESS
The consumer business is the reason and the ultimate target for the existence of our company. We firmly believe that only the product itself can prove the value and meaning of a company, can mark and maintain the vitality of a company, can eventually fulfil a company's business purpose and social duty.
We are mainly focusing on the consumers of China mainland market. By the advantages of China's fast-growing economy and booming E-Commerce channels, Chinese detergent consumer market is enjoying a rapid developing speed. The market is showing features of more items, more specialized, more liquid items, more concentrated, greener and healthier, longer effect, more new and young brands, and shorter supply chains and etc.
Based on the features of China consumers' market, combining our company's own advantages, we confirmed 4 application scenes as our developing direction, such as laundry, kitchen, household and car-use scenes. For better development of this department, we formed Nanjing XPinhui Daily Chemical Co.,Ltd. In 2020, and built our first detergent pods factory in Henan province with Luoyang Qihang Chemical Co., Ltd., registered the brands of Yike® and Huibox®.
Beside our own products and OEM items, we are also dedicated in introducing our industrial customers' featured and cultured cleaning products into China market. Chinese consumers can reach our consumer items in most E-commerce platforms like JD, Tiktok and ******.
