The Process

A typical manufacturing process would be as follows: 

• Water is metered into the process vessel. This is often heated to around 130-140℉ (55-60℃) to aid dilution/hydration of other ingredients.
• The first ingredient added is normally the surfactant, as other additives, particularly those which affect viscosity, can make dilution of the surfactant more difficult.
• Conditioners and other ingredients are added.
• pH is adjusted to the required level.
• Sodium chloride or other viscosity modifiers are added last, along with color and fragrance.

Formulations vary widely, however, the range of ingredients used can be summarized in the following table:

The Problem

A number of problems can be encountered when using conventional agitators:

• Aeration must be avoided, as this can lead to clouding of clear shampoos, and problems where packaging is filled by volume rather than weight.
• “High Active” products require special handling, see Application Report “Dilution of High Active Surfactants.”
• Silicones are immiscible with water and can be chemically incompatible with some surfactants, making them very difficult to emulsify or suspend.
• Agitators do not produce sufficient shear to reduce silicones to the finest possible droplet size and obtain a stable emulsion/suspension. They will tend to vortex, increasing aeration.
• Many ingredients have a much higher viscosity than water. When blending these with an agitator, the higher viscosity material can form globules which are simply washed around without being diluted/dispersed.
• Thickening agents such as carbomers, and cellulose or gum based products may require high shear mixing to be “activated.”
• The addition of sodium chloride becomes increasingly difficult as the viscosity rises.
• Vigorous agitation is required to overcome these problems, however, with conventional agitators this can lead to aeration.

The Solution

Stage 1

The vessel is charged with water. The in-tank agitator and In-Line mixer are started, and the surfactant and other ingredients are added in the order specified. The powerful suction created by the In-Line mixer draws the materials through the pipeline into the rotor/stator workhead.

Stage 2

Centrifugal force drives the materials to the periphery of the workhead where they are subjected to intense high shear in the gap between the rotor and stator.

Stage 3

The product is forced out through the stator and recirculated back to the process vessel as fresh material is drawn into the workhead.

The Advantages

• The high shear mixing action of a Silverson can rapidly blend liquids of widely differing viscosities.
• The In-Line mixer, pipework and vessel form a closed system, eliminating aeration.
• Dramatic reduction in mixing times.
• Significantly better yield of thickening agents than can be achieved by traditional methods.
• Consistent product quality and repeatability.

The following Silverson machines are used for this application, the suitability of which is dictated by factors including batch size, formulation and viscosity of the end product.

VẤN ĐỀ GẶP PHẢI

Using conventional agitators, some aspects of this process present considerable difficulty to the processor:

• Hydration of gums and thickeners is one of the most difficult mixing operations. In some cases the solution has to be agitated for a long period to ensure the gum is fully hydrated.
• Agglomerates can easily form. These are not easily dispersed using conventional agitators.
• Partially hydrated material can build up on the shaft of the mixer and on the vessel wall.
• A uniform pre-emulsion is required by the high pressure homogenizer. This is not possible using conventional agitators.
• This will result in the product having to be passed several times through the high pressure homogenizer in order to obtain the desired globule size.

ƯU ĐIỂM

• After processing with a Silverson mixer, a single pass through a high pressure homogenizer is normally sufficient to achieve the end product.
• The high pressure homogenizer can normally be eliminated for spray-dried products.
• Typically a globule size of 5-7μm is achievable with a Silverson high shear mixer.
• Maximized yield of raw materials as thickening agents are fully hydrated and other ingredients fully dispersed.
• Consistent product quality.
• Agglomerate-free mix.
• Stable emulsion.
• Rapid mixing times.

The batch size, formulation, type of ingredients used and the viscosity of the end product dictates which machine from the Silverson product line is suited to individual processing requirements.

VẤN ĐỀ

• High Active Surfactants and water are of widely differing viscosities. If surfactants are pumped into the water in the vessel, they are not easily blended by conventional agitators. This can lead to globules of surfactant remaining undiluted or being partially diluted.
• Long process times are required to ensure a uniform product.
• Some formulations are too viscous for conventional mixers and centrifugal pumps.
• If the concentration on dilution exceeds 27%, SLES forms a highly viscous gel.
• Introduction of air greatly increases viscosity, therefore aeration must be avoided.

GIẢI PHÁP

Batch Systems 

Dilution is best carried out using a high shear In-Line mixer. A Silverson In-Line mixer can be used as illustrated in figure 1 below. Water is charged into the vessel and recirculated by the self-pumping Silverson In-Line mixer. The High Active Surfactant is pumped into the water stream immediately prior to the In-Line mixer. The mixer's rotor/stator workhead ensures a uniform mix which is then recirculated back into the vessel. 

Continuous Systems

All ingredients are metered into a Silverson Multi-stage In-Line mixer for continuous, single pass dilution.
