This article investigates the effect of hydrophobic supercritical CO₂ raspberry seed extracts on the physicochemical and functional properties of a modern, transparent fabric softener. The addition of a hydrophobic extract to a transparent softener formulation increased the turbidity and dynamic viscosity of the product compared to the reference formulation (with no added extract). In addition, fabric rinsed in a bath containing the transparent fabric softener enriched with the hydrophobic extract was characterized by a higher degree of softness and slightly lower values of fabric rewettability (two parameters determining the usable properties of this type products) in relation to the values determined for a fabric exposed to the rinsing process in an aqueous solution of the transparent fabric softener without added extract. The results obtained in the assessment of physicochemical properties point to the modification of the structure of fabric softener resulting from the growth of surfactant aggregates due to solubilization of the hydrophobic extract. As a consequence, the deposit—an adsorption layer of surfactants (responsible for key characteristics relevant to the performance of this type of products) remaining on the fabric after the rinsing process—is modified.

疏水性植物提取物对透明织物柔软剂理化性质的影响

本文研究了疏水超临界CO _2的作用覆盆子籽提取物对现代透明织物柔软剂的理化和功能特性的影响。与参考配方（不添加提取物）相比，向透明软化剂配方中添加疏水性提取物可提高产品的浊度和动态粘度。另外，在含有富含疏水性提取物的透明织物柔软剂的浴中漂洗的织物的特征在于，相对于该值，较高的柔软度和较低的织物可湿性值（两个参数决定了这类产品的可用性能）在没有添加提取物的情况下，在透明织物柔软剂的水溶液中对暴露于漂洗过程中的织物进行测定。在理化性质评估中获得的结果表明，由于疏水性提取物的增溶，表面活性剂聚集体的生长导致了织物柔软剂结构的改变。因此，漂洗后残留在织物上的沉积物（一种表面活性剂的吸附层（负责与这类产品的性能有关的关键特性））被改性。
