 Code / referred to as the AOS 
 Alias ??alpha-olefin sulfonate 
 Formula the RCH = CH (CH2) n-SO3Na the RCH (OH) (CH2) n-SO3Na n = C14-16 or C14-18 
 20200-2006 a quality standard GBT-ene sulfonate 
 Performance 
 2.1 AOS surfactant 
 AOS and other anionic surfactants (such as LAS, AS, AES) also has excellent surface activity in a certain concentration range, the AOS can water surface tension from 72mN.m-1 to 30-40mN.m- about 1. At 25 ℃ measured by surface tension of several anionic surfactant critical micelle concentration (cmc) as follows: 
 Table 1 several anionic surfactant critical micelle concentration (cmc) 
 Name sodium laurate of K12 the LAS AOS14-16 AOS14-18 AOS16-18 
 Cmc 5.3 2.3 0.65 0.60 0.40 0.20 




 2.2 the AOS solubility 
 Under the same conditions, C12, C14, C16, C18 AOS were given determination, with the growth of the carbon chain, the solubility decreased. But has good solubility in a wide range of carbon number (C12-C18). The carbon number distribution for the C14, C16 AOS good solubility, can be used in liquid detergents. 




 Wetting power of 2.3 AOS 
 Surfactant at room temperature under 27 ℃, dubbed 0.1% deionized water, surfactants, wetting time measured by immersion. Wetting force descending order as follows: 
 LAS> AOS14-16> AES ≈ K12> AOS14-18> MES 




 2.4 AOS blistering 
 AOS, LAS, K12, AES anionic surfactant have better foaming power, comparatively speaking, AOS14-16 AES foaming. Both hard and soft water conditions, AOS14-16 the AOS14-18 and AES foam force change little. LAS and K12, due to poor resistance to hard water capacity in hard water foam, significantly lower. Sebum exist, the AOS foam edge slightly higher than AES and AS. In addition, the AOS foam soap, etc. to be suppressed. 




 Anti-hard water capacity of 2.5 AOS 
 Titration of surfactant solution with CaCl2 solution, from weak to strong order for the solution is cloudy as to determine the end point of the surfactants in hard water tolerant (CaC03 dollars): 
 Of K12 2.6 AOS calcium soap dispersing power 
 The amount of acid titration and turbidimetric method based on determination of the conditions of 40 ° C and room temperature 20 ° C, respectively, α-alkenyl sulfonate, alcohol ether sulfates, fatty acid methyl ester sulfonates surfactants calcium soap dispersion properties, dispersing power from weak to strong order to: 
 Detergency of LAS 2.7 AOS 




 Anionic surfactant phosphorus washing powder 16% Sodium tripolyphosphate 18%, soda ash and sodium silicate components joined by the requirements of GB detergent. Laundry detergent in the GB dirty cloth, bottle decontamination on the decontamination experiment, detergency from highest to lowest order as: 
 AES (EO = 3)> AOS14-16> AOS14-18> K12> LAS 
 Anionic surfactant in the non-phosphorus washing powder 18%, 4A zeolite 20%, soda ash and sodium silicate, polymers and other components joined by the requirements of GB detergent. Laundry detergent in the GB dirty cloth, bottle decontamination on the decontamination experiment, detergency from highest to lowest order as: 
 AES (EO = 3)> AOS14-16> AOS14-18> K12> LAS 




 2.8 the AOS biodegradable 
 In the anionic surfactant, the biodegradation of the deterioration of the order of nature in accordance with AS> the AOS> the MES> the AES> of LAS> ABS. 
 AOS biodegradation rate and ultimate biodegradability were significantly higher than LAS, and 5-7 days in the natural environment can be completely degraded and disappear, does not pollute the environment. LAS shall be 20-22 days before 100% degradation. 


 2.9 the AOS on human security 
 The acute toxicity of soap, synthetic detergent mostly by rats, mice and the like small animals, acute LD50 values ??(LD50) said that the use of soap and synthetic detergent surfactant of mice are listed in Table 2 oral toxicity. 
 Table 2, use soap and synthetic detergent surfactants oral toxicity to mice 
 Sample soap is the AE the APE AS AES the AOS the SAS of LAS 
 LD50, g / kg> 10 5-15 1.7-> ??5 2.5-> 4 1-3 0.65-2 1-3 1.6-25 
 Table 2 shows, in general anionic surfactant toxicity was 5-10 times higher than the soap, the AOS of the smaller toxicity of LAS is greater, in addition, the toxicity of the non-ionic surfactants and anionic surface active agent, toxicity roughly the same. 
 Drawn through the skin post deposition experiments: the anionic surfactant stimulating the AS> of LAS> the AOS> of AES, the homologue C12,> of C14> C16 ≈ C18 sequence weakened. 
 LAS, AS and AOS eye irritation, LAS and AS above the 0.1% concentration, the mucous membranes of the eyes clear stimulus. AOS in the 0.1% concentration, only a small amount of congestion, the AOS concentration of 0.5% eye mucosa obvious stimulus. The three surfactants at low concentrations are not irritate the eye mucosa, by rinsing can make the irritation disappeared. 
 Experimental results show that the AOS is safe for humans and the environment.
