When light passes through a liquid, if any particles or incompatible domains larger than one-tenth of the wavelength of visible light exist, scattering occurs, resulting in reduced transmittance. Therefore, achieving high transparency essentially requires that all components in the formulation\u2014particularly functional macromolecular thickeners\u2014are perfectly dissolved and uniformly dispersed at the molecular scale.<\/span><\/p><p class=\"ds-markdown-paragraph\"><span class=\"\">Among the numerous thickener options, <a href=\"https:\/\/tenessy.com\/products\/cellulose-ether\/\">selulosa eter<\/a> has become an essential functional additive in <a href=\"https:\/\/tenessy.com\/applications\/daily-chemical-solution\/\">liquid detergent<\/a> formulations, owing to its excellent thickening efficiency, good salt compatibility, and non-ionic characteristics. However, not all cellulose ethers are capable of meeting the demands of high-transparency formulations. From molecular design to production processes, from dissolution behavior to long-term stability, deviations at any stage can leave &#8220;defects&#8221; in the final product&#8217;s transmittance.

Non-ionic cellulose ethers are minimally affected by pH in terms of intrinsic solubility; however, pH indirectly modulates the colloidal stability of the entire system by influencing surfactant protonation states, fragrance hydrolysis rates, and preservative activity. Cellulose ethers exhibit excellent salt tolerance, but caution is required regarding the critical concentration of &#8220;salting-out&#8221; effects\u2014when electrolytes accumulate to a threshold, the hydration layer of molecular chains is compressed, potentially causing chain collapse and precipitation, which elevates turbidity.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b24e058 elementor-widget elementor-widget-heading\" data-id=\"b24e058\" data-element_type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">2.
