Stabilization and Dispersion of OSA Starch-Coated Titania Nanoparticles in Kappa-Carrageenan-Based Solution AuthorChen, Xingyu; Wu, Kai; Zeng, Sili; Chen, Da; Yao, Lingyun; Song, Shiqing; Wang, Huatian; Sun, Min; Feng, Tao Year2022 SourceNanomaterials LanguageEnglish Pages1519 LUMiSizerLS3015Accelerated Stability Tests Dispersions of OTP in κ-CG-based solution or water were adjusted to pH 7. They were loaded to a dispersion Analyzer (LUMiSizer dispersion Analyzer 15 more BerlinGermany). the instability index of colloids system was plotted against the OTP mass fraction. With the increase in OTP contentcolloids system became much more unstable (i.e.relatively higher instability index value). For the same content of OTPdispersing in a κ-CG solution showed a lower instability index than that in deionized water (Figure 9). High content of pigment particles generally represented wider particle size distributionwhich was often taken as the contributor to instability of slurry [35]. Thereforehigher OTP mass fraction would result in an increase in instability for both a κ-CG-based solution and deionized water. Dispersing OTP in a κ-CG solution revealed relative low instability index (0.34) at the maximum tested content (60%). In consideration of the high pigment content and stability in cosmetic productsOSA starch-coated titania nanoparticles in a κ-CG solution was suggested to be an efficient and useful method for dispersing pigments in an environmentally friendly colloidal system. TiO2a new method for stabilization and dispersion of titania pigment was developed. The agents involved in stabilization and dispersion of titania are natural in origin and biodegradablewhich is considered as a better alternative for the cosmetic industry and consumers. Titania pigment was firstly coated with OSA starch through spray drying to form nanoparticles. Thereafterthe nanoparticle was dissolved in a low-concentrated κ-CG-based solution. In additionrheologytransmission electron microscopy (TEM) and accelerated stability tests were used to assess the effect of OSA starch on pigment particle dispersion. The proposed method would not only improve the dispersion and suspension of titania pigmentbut may also be applicable to other pigments in food and cosmetic products for similar purpose.

Stabilizing Both Oil Droplets and Titanium Dioxide Nanoparticles in Aqueous Dispersion with Nanofibrillated Cellulose AuthorCaroline E. P. Silva, Juliana S.

Nanocellulose is a well-known stabilizer for several colloidal dispersionsincluding emulsions and solid nanoparticlesreplacing surfactantspolymersand other additivestherefore providing more minimalist and eco-friendly formulations. Howevercould this ability be extended to stabilize oil droplets and inorganic nanoparticles simultaneously in the same colloidal system. This work aimed to answer this question. For thiswe have evaluated either cationic or anionic nanobrillated celluloses to stabilize both titanium dioxide nanoparticles and oil droplets. The resulting suspensions hold their macroscopic stability for up to 2 monthsregardless of pH or NFC surface charge. Cryo-TEM images revealed a complex network formation involving nanofibers and TiO2NPswhich agrees with the high viscosity values and gel-like behavior found in rheology measurements. We propose that the formation of this network is responsible for the simultaneous stabilization of oil droplets and TiO2NPsand that this may be used as a formulation tool for other complex systems.

Stable metal ion containing compositions AuthorXiao Yi Huang, Xiong Fei Qin, Yuan Hui Xie, Yun Xu Year2022 SourceU.S. patent number 11,253,446 LanguageEnglish 2615Colgate-Palmolive CompanyPhase separation of a composition can be predicted using a centrifugation method. Samples are centrifuged using an analytical centrifuge (LumiSizer 110 from L.U.M. GmbHBerlin) 16 more which measures separation of the product by measuring optical transmission through the tube as a function of time. The centrifugation method generates a number known as the "wall liquid separation scale number"N. Sample stability is considered as acceptable when N.ltoreq.3 and unacceptable when N>3. The lower the N valuethe more robust the formula (i.e. the higher its resistance to phase separation). Most oftena value of N which is less than 1.5 is necessary to ensure a greater confidence in predicting real time stability. The centrifugation method was used to predict the likelihood of phase separation for each of the formulations A to E above for 3 years shelf life at ambient temperature.
