Described herein, a transparent soap bar for cleaning the skin including a soap surfactant, a synthetic surfactant, a fragrance component, an amine component, an antioxidant salt, wherein the transparent soap bar has a percent transmittance (% T) value of greater than 40% as measured using the method of Measurement of % Transmittance.

A skin cleansing system and method for visual indication of an efficacious cleansing duration provides a cleaning composition that works to kill germs; and then visually indicate, through color, when a sufficient cleaning duration, of approximately 20 seconds, of cleansing has occurred. The cleaning composition comprises a liquid soap and a colored moisturizer that remain separated in a dispenser, but combine simultaneously when applied to the skin for washing with water. The soap requires a cleaning duration of about 20 seconds to kill the germs. The soap also requires the same cleaning duration of 20 seconds to dissolve the nonpolar oils in the colored moisturizer. Thus, when the colored moisturizer washes away, this is an indication that the germs have also washed away. The dissolving action is a result of the nonpolar tail of the soap engaging and destroying, both the germs and the nonpolar oils in the colored moisturizer.

The present disclosure is related to apparatuses, processes, and extrusion screws directed to process solid detergent compositions in shapes like billets, bars, tablets, noodles, and similar shapes produced from extruded synthetic detergents, soaps, and combinations thereof. The present disclosure describes an extrusion screw for processing synthetic detergents, soaps, and combinations thereof. The extrusion screw comprises a feed section, a metering section, and a compression section. Said compression section has a proximal channel depth adjacent to the feed section, and a distal channel depth adjacent to the metering section, and a compression ratio that may be between 2.2, and 4.1, for example, between 2.2, and 2.6. The extrusion screw may have a length to diameter ratio (L/D) that may be between 4.0, and 6.0. The present disclosure also describes an apparatus for processing synthetic detergents, soaps, and combinations thereof. The apparatus comprises a barrel and said extrusion screw. The present disclosure also describes a process for extruding solid synthetic detergents, soaps, and combinations thereof. The process comprises a step of providing a formulation that may be selected from synthetic detergent, and half-synthetic soap to said apparatus, and compressing said formulation at a temperature between 32° C., and 42° C. with a compression section of the extrusion screw. The screw rotation speed of the extrusion screw may be between 4, and 20 RPM. The formulation may be provided prewarmed. The screw rotation speed of the extrusion screw may be between 4, and 35 RPM (e.g., between 4 and 20 RPM).

Various waste fractions from meat, gravy, and animal feed industries, that are difficult to recycle, as well as wastes, for example, from fishing and fish processing, are often challenging to separate for further processing into products. The hygienic and otherwise safe and economical utilization of these, consistent with ecologically sustainable development, requires the development of new methods. According to the method and apparatus of this invention, with the help of microbes and their enzymes, for example, bone and tissue waste, as well as protein, fat material or materials containing blood matte, that have been separated during meat processing, can be fractioned into new raw materials. Gained products can be, for example, energy fractions and gases, waxes and various organic fertilizers and soil improvement substances.

Use of the composition for eliminating efflorescence.

The invention relates to a process for treating vapours released from lignocellulose biomass during acid treatment at elevated temperature of the lignocellulose biomass. The process comprises condensing (3) the vapours to produce a condensate, adjusting (4) the pH of the condensate to about 9, and decanting (5) the condensate to produce turpentine, and may further comprise distilling (6) the mixture remaining after decanting to produce furfuraland a reject comprising tall oil fatty acids. The invention also relates to a corresponding system for treating vapours released from lignocellulose biomass during acid treatment at elevated temperature of the lignocellulose biomass.

Perfumed latex soap is prepared from the following components in parts by weight: 2-5 parts of natural latex, 5-12 parts of glycerin, 8-10 parts of sodium dodecyl sulfate, 5-10 parts of coconut oil, 6-8 parts of palm oil, 1-3 parts of titanium dioxide, 0.8-1.2 parts of ethylenediamine tetraacetic acid, 0.6-0.8 part of sulfur, and 0.8-1.0 part of radix asparagine essential oil. The perfumed latex soap is mild, safe, and non-irritating and has aroma of the natural latex. In addition, the added radix asparagine essential oil can effectively improve the skin condition of a human body without causing the human body to generate dependence. The temperature of the mixing tank in which the perfumed latex soup is prepared is convenient to adjust and materials in a mixing cylinder can be agitated and sheared during agitating, so that the materials are fully mixed and the quality of a product is improved.
