In defining "formulation,” one may consider it as the blending of a different compound that is not- reactionary among themselves to ultimately get a combination that bears some specific characteristics (Conte et al, 2011). Its key importance is the assembling of different components in suitable structures and relationships based on a certain combination formula. A combination of these compounds is made based on a products' standard.
Various products are considered to be made out of a combination of various elements. These products include; paints, food, medicinal tablets, and liquid detergents among others. These products are made out of a combination of various products in a certain proportion that is considered in the formulation. Product designs, therefore, focus much on the results of the combination of various materials. In this case, the formulation is developed systematically under the following five-step:
- Stipulate the end quality that is to be obtained.
- Identify data required to gather the composition of raw materials, the cost, and the qualities.
- Determine the processing variables to be used including the raw materials limits.
- Identify the methodology to use including; experimental design, linear programming, and quantitative techniques.
- Profile the products and consider conducting a test to determine their validity that would help formulation achieve the required quality.
This paper will seek to discuss various products that have been formulated. Various techniques will be discussed for each formulated product. The products in consideration, therefore, will include; pharmaceutical tablets, liquid detergents used in laundry and paints.

Excerpt from the Book
2.1 Particle Size Analysis of Pigments using Laser Diffraction
Paints include various element, and the characteristics of these elements have a significant impact on the final product. Paints contain roughly 40% of Pigments and extenders, measurement of their particle size serves as an excellent predictor of the final product quality, therefore, it is considered to be a critical parameter in paints that affects surface finish. In order to reduce the problems related to paints quality, it is important to characterise the pigment sample at the microscopic level as it is an important element to providing good quality paints. Rheological behaviour such as viscosity, flow rate thixotropic behaviour or adhesion is also affected by the particle size distribution. (Debnath and Vaidya, 2006)
Various paint pigments work by selectively absorbing and reflecting a certain wavelength of light (figure 2) (Particle, 2008). The ability of a paints pigment to absorb a certain wavelength of light increases by reducing the particle size, until when the particles reach a point where it becomes translucent to the incident light. This factor makes the measurement of pigment particle size extremely important to it performance. (Application Information, 2014).
For a comprehensive pigment characterization, there are a number of analytical techniques which includes FT-IR, SEM/TEM, EDX, XRD and laser diffraction to establish shape/particle size, functional group and particle size distribution etc. (Debnath and Vaidya, 2006). Various different particle sizing technologies are being currently used to measure the particle size distributions of pigments but, LASER DIFFRACTION is considered to be the most common technique for determining the particle size distribution of liquid media of low viscosity such as paints. It enables comparison of the effectiveness of dispersion techniques (McGarvey, McGregor and McKay, 1997), mainly due to its ease of use and the varied ways that sample can be presented for analysis. (Application Information, 2014).
