Must Know Green Surfactant Alkyl Glycoside (APG)

October 25,2021

People are more inclined to use natural detergents, which requires more and more mild surfactants. Detergent manufacturers hope to use high quality alkyl polyglucoside surfactants (green surfatcant) to improve the decontamination ability of their products, but different products have different emphasis.

Get to know APG first

Alkyl glycoside (abbreviated as APG) is a new type of high-efficiency, non-toxic, biodegradable non-ionic surfactant. It has good surface activity. After compounding, it can form the best surfactant at present. Alkyl glycoside has very excellent performance. , Low surface tension, strong foaming power, stable foam, good wettability, excellent compatibility, low irritation to the human body, extremely low toxicity, and rapid biodegradation. It is currently the only non-toxic grade in the world. Therefore, alkyl glycosides are also known as "world-class" surfactants for their superior performance.

 

Brief history of alkyl glycosides

Alkyl Glycoside (APG) has been researched for more than 100 years. The foreign research on APG was earlier, but its industrialization was late.

 

Alkyl glycoside properties

Physical properties and solubility

APG products are mostly made into 50%~70% aqueous solution, pure APG is white powder, the actual product is cream, light yellow to amber. APG is a moisture-absorbing solid, generally soluble in water, and more easily soluble in common organic solvents. It exhibits excellent compatibility, stability and surface activity in acid and alkaline solutions, especially in active solvents with higher inorganic components.

 

Biodegradability

The ability to be degraded by microorganisms is an important elimination mechanism to prevent the accumulation of surfactants in the environment to dangerous concentrations. Alkyl glycosides are synthesized using starch and its hydrolysates and fatty alcohols as raw materials. Alkyl glycosides can be completely biodegraded in nature and will not form metabolites that are difficult to biodegrade, thereby avoiding new pollution to the environment.

 

Detergency

The detergency of surfactants varies with ion types, washing conditions, and soil types. The sebum dirt on polyester/cotton is sensitive to non-ionic detergents. APG has the same decontamination effect as fatty alcohol polyoxyethylene ether sodium sulfate (AES), and is better than linear alkyl benzene sulfonate (LAS), AS And SAS.

 

Surface activity

Fatty alcohol alkyl carbon chains provide non-polar lipophilic groups, so usually alkyl glycosides with alkyl carbon chain lengths greater than 8 carbons have surface activity and critical micelle concentration (CMC). As the chain grows, its surface tension is significantly reduced, and the CMC value also decreases, indicating that its activity is significantly improved. According to reports in the literature, APG is compared with fatty alcohol polyoxyethylene ether (AEO) and LAS, and it is concluded that lauryl alcohol alkyl glycoside has good surface activity.

APG in washing products

In washing, it can be used as the main surface activity or as the auxiliary surface activity. In the washing products, the common features are foam, cleansing power, state, and washing feeling. Different points need to be different according to the product application.

 

For example, shampoo products should consider the conditioner, that is, the softness after washing, and choose the foam according to the foam you want. If you want high foam, that is, big bubbles, you can think of AES, K12 and phosphatidic acid; if you want low foam, you can also think of small bubbles, you can think of amino acids; if you want rich layers, you can do this Two kinds of bubbles are used in combination. Regarding bubbles, many people think that the bigger the bubbles, the more clean they can be. This kind of thinking is wrong. Whether they can be cleaned is related to the active content.

 

Regarding the feeling of washing, many people also determine the cleanliness by the feeling of washing. They think that the feeling of astringency after washing means that the washing is very clean, and the feeling of smoothness means that the washing is not clean. It is also a problem of cleanliness. The decision lies in the content of the active ingredient*addition. Whether or not the sum of the products meets the national standard has nothing to do with foam and wash feeling.

 

Product status

Creamy, such as our amino acid cleansing cream and shampoo; mousse-like, such as Pechoin's acne-removing foaming cleansing cream; many powdered ones, such as washing powder and bath salt; and some are milky, amino acid facial cleanser.

 

Green products are the general trend. High quality alkyl polyglucoside surfactants make detergents greener and healthier, and it sets people at ease. If you have green and healthy detergents, cosmetics, cleaning agents, etc., you can contact us to get more information about alkyl polyglucoside surfactant.
