AOSIt is widely used in all kinds of washing and cosmetics, such as: as the preferred raw material for washing powder, composite soap, tableware detergent and phosphorus free detergent; Used as shampoo, bath, facial wash and other cleaning cosmetics; It can also be used in industrial detergents.  It is widely used in all kinds of washing and cosmetics, such as: as the preferred raw material for washing powder, composite soap, tableware detergent and phosphorus free detergent; Used as shampoo, bath, facial wash and other cleaning cosmetics; It can also be used in industrial detergents.  With excellent decontamination power, good foaming power, foam stability, emulsifying power; Extremely soluble in water, with strong calcium soap dispersion and hard water resistance; It has good biodegradability and is gentle to skin; Good compatibility; The products containing AOS are rich in foam, delicate, and easy to rinse.  surface activity  AOS and other anionic surfactants (such as LAS, AS, AES, etc.) also have excellent surface activity. Within a certain concentration range, AOS can reduce the surface tension of water from 72 mN. m-1 to 30-40 mN About m-1. The critical micelle concentration (cmc) of several anionic surfactants measured by surface tension method at 25 ℃ is as follows:  The following table shows the critical micelle concentration (cmc) of several anionic surfactants  Name Sodium laurate K12 LAS AOS14-16 AOS14-18 AOS16-18  Cmc 5.3 2.3 0.65 0.60 0.40 0.20  Solubility  Under the same conditions, the AOS of C12, C14, C16 and C18 were measured respectively. With the increase of carbon chain, the solubility decreased. However, it has good solubility in a wide range of carbon numbers (C12-C18). AOS with carbon number distribution of C14 and C16 has good solubility and can be used in liquid detergents.  Wetting power  At room temperature of 27 ℃, prepare the surfactant into 0.1% deionized water solution, and measure the wetting time of several surfactants by immersion method. The order of wetting force is as follows:  LAS>AOS14-16>AES≈K12>AOS14-18>MES  Bubbliness  AOS, LAS, K12, AES and other anionic surfactants all have good foaming power. In comparison, AOS14-16 and AES have the best foaming power. In hard water and soft water, the foaming power of AOS14-16, AOS14-18 and AES changed little. However, the foaming power of LAS and K12 decreased significantly in hard water due to their poor resistance to hard water. In the presence of sebum, the foaming power of AOS is slightly higher than that of AES and AS. In addition, the foam of AOS can be inhibited with soap, etc.  Hard water resistance  Titrate the surfactant solution with CaCl2 solution, and determine whether the solution is turbid as the end point. The order of resistance to hard water of several surfactants (calculated by CaC03) from weak to strong is as follows:  K12  Calcium soap dispersibility  Based on the acid titration method and turbidimetric method, it is measured at 40 ℃ and room temperature 20 ℃ respectively, α- The calcium soap dispersion characteristics of alkenyl sulfonate, alcohol ether sulfate, fatty acid methyl ester sulfonate and other surfactants, and the order of dispersion strength from weak to strong is:  LAS  Detergency  The anionic surfactant 16%, sodium tripolyphosphate 18%, soda ash and Paohua alkali in the phosphorus containing detergent powder are added according to the requirements of the national standard for detergent powder. The decontamination test of washing powder on the national standard dirty cloth and bottle type decontamination machine shows that the order of decontamination power from high to low is:  AES(EO=3)>AOS14-16>AOS14-18>K12>LAS  The anionic surfactant 18%, 4A zeolite 20%, soda ash, Paohua alkali, high polymer and other components in phosphorus free detergent powder are added according to the requirements of the national standard for detergent powder. The decontamination test of washing powder on the national standard dirty cloth and bottle type decontamination machine shows that the order of decontamination power from high to low is:  AES(EO=3)>AOS14-16>AOS14-18>K12>LAS  Biodegradability  In anionic surfactant, its biodegradability becomes worse in the order of AS>AOS>MES>AES>LAS>ABS.  The biodegradation rate and final biodegradation degree of AOS are significantly higher than those of LAS. AOS can be completely degraded and disappear within 5-7 days in the natural environment, and will not pollute the environment. LAS can be 100% degraded within 20-22 days.  Security Edit Broadcast  The acute toxicity of soap and synthetic detergent is mostly represented by the acute LD50 (median lethal dose) of rats, mice and other small animals. Table 2 lists the oral toxicity of soap and surfactant used as synthetic detergent to rats.  Table 2 Oral toxicity of soap and surfactant used as synthetic detergent to rats  Sample Soap AS AES AOS SAS LAS APE AE  LD50,g/kg >105-151.7- >5 2.5- >4 1-3 0.65-2 1-3 1.6-25  It can be seen from Table 2 that the toxicity of general anionic surfactants is 5-10 times higher than that of soap, AOS is slightly less toxic, and LAS is greater. In addition, the toxicity of non-ionic surfactants is roughly the same as that of anionic surfactants.  According to the skin application experiment, the irritation of anionic surfactant is generally AS>LAS>AOS>AES, which is weakened in the order of C12>C14>C16 ≈ C18 in the homologues.  Comparing the irritation of LAS, AS and AOS to eyes, LAS and AS have obvious irritation to eye mucosa when the concentration is above 0.1%. When AOS concentration is 0.1%, there is only a small amount of congestion, and when AOS concentration is 0.5%, there is obvious irritation to the eye mucosa. At low concentrations, the three surfactants did not irritate the eye mucosa, and the irritation disappeared after rinsing.  A large number of experimental results show that AOS is safe for human body and environment.  Purpose and application editing and broadcasting  Application of washing powder  The decontamination test showed that LAS and AOS had a good synergistic effect in both phosphate containing and phosphate free powders. The synergistic effect of LAS: AOS at 8:2 was the most significant among phosphorus containing detergent powders. When the proportion of AOS in the anionic active component is more than 20%, the decontamination of phosphate free detergent powder with LAS and AOS as the anionic active components is significantly improved. The decontamination synergism of AOS in phosphate free detergent powder is more prominent than that in phosphate containing detergent powder.  AOS and enzyme have good compatibility. The residual enzyme activity in detergent solution containing domestic protease and imported protease (such as Savnase) was measured and compared. As time went on, the residual enzyme activity of the anionic active component pure LAS was lower, while the residual enzyme activity in detergent solution partially or completely replacing LAS with AOS was higher.  The decontamination of AOS and LAS at higher temperature and for a long time (for example, above 60 ℃, washing for 1 hour) has little difference. However, when washed at room temperature (10-40 ℃ for 10-29 minutes), the decontamination power of AOS is higher than that of LAS. Compared with LAS, AOS has stronger ability to resist hard water, so it has more advantages in areas with higher hard water.  LAS has superior decontamination power for oil/granules, while non-ionic substances such as fatty alcohol ether are most suitable for cleaning dust and skin dirt. Only when they are combined can good decontamination effect be obtained, while AOS has good decontamination effect for sebum dirt and oily and powdery dirt.  The amount of ash deposition on the fabric after washing with phosphate free detergent containing 4A zeolite, sodium carbonate, sodium carbonate and other auxiliaries should be noted. The non phosphorus detergent with AOS partially replacing LAS is less ash deposition than that with LAS alone, which is not easy to harden and turn yellow. (Refer to the allocation plan)  Application of soap  Soap forms insoluble soap scale in hard water, which affects the decontamination effect. Adding AOS can improve the solubility of soap in water, and the wetting power and foam power of soap liquid at low temperature also increase rapidly. When AOS is added to the soap with fatty acid sodium as the main component, the properties of the soap are improved, the foaming force is enhanced, the hard water resistance is improved, the flexibility is enhanced, and the soap is not easy to crack. The reference formula is as follows:  Formula soap based AOS AES essence pigment, titanium dioxide  1 97.8 3.5/0.5 Appropriate  2 96.8/4.5 0.5  Liquid detergent application  Because LAS is highly irritating, many washing products no longer use LAS as an active component, while AOS has low irritation and good biodegradability, so it is a more appropriate substitute. AOS has a great influence on the viscosity of the product in liquid detergents. It is not ideal to use the commonly used fatty alcohol diethanolamide and Na Cl to improve the viscosity. The use of fatty alcohol monoethanolamide, amine oxide, betaine and NH4Cl can play a very good role in increasing the viscosity. Because of the characteristics of AOS in decontamination, hard water resistance and viscosity, AOS is widely used in liquid detergents with high active components. The reference formula is as follows (tableware detergent):  Formula LAS AES AOS 6501 EDTA polymer antiseptic, essence water  1 6. 8 6.8 6.5 3.0 0.2 0.3 Proper allowance  2 8. 5 2.0 8.5 3.5 0.2 0.9 Appropriate margin  Application of personal care products  The mildness of AOS is comparable to that of AES, while the irritation of LAS and AS is much greater than that of AOS. Therefore, AOS has a wide range of applications in personal care products. AOS is extremely stable under acidic conditions. The skin of normal people is weakly acidic (pH value is about 5.5), which is suitable for using AOS as a component of personal washing products. The shampoo with AOS as the main active component has better foaming property than that with K12. Rinso reported that the foam released by AOS was plump and creamy, and felt like soap when washing. This feature is just suitable for Chinese washing habits. Therefore, AOS can be used in personal care products such as bath liquid, hand sanitizer and facial cleanser. Reference allocation strategy  Other applications  AOS is widely used in textile printing and dyeing industry, petroleum chemicals, tertiary oil recovery, industrial cleaning, etc. AOS can be used as concrete density improver, foam wallboard and foam agent for fire fighting. It can also be used as pesticide emulsifier, wetting agent, etc.  Packaging edit broadcast  Powder products, 25kg plastic lined woven bags and plastic lined kraft paper bags; Liquid product 200kg plastic drum
