Why pharmaceutical colours are so important?

Every colour has an influence on the human mind. No wonder, colour science remains significant in the consumption behaviour of medicines by patients. Colour is not merely selected by pharma companies but it is carefully chosen after extensive research. Pharmaceutical colors manufacturers follow certain standards to create the suitable colours for various medicines because colour properties can expedite the wellness of patients and provide other benefits.

Colour – The Healer

Every colour signifies something. If blue is for calmness then red is for vitality. The colour itself starts the healing process even before the medicine is consumed. Colour enhances the effect of medicine on different illnesses.

Identify better with colour

Apart from the visual appeal, colours are used in medicine to differentiate them and thus, avoid confusion. Elderly patients will find it easier to find the right medicine based on colour codes. Pharmaceutical Colour Measurement devices help to select the right consistency and attain accuracy in colours. The exact proportion of colour should be used as per the guidelines of regulatory authorities for appropriate usage of colours in pharma products.

Follow standards for wellness

Pharmaceutical colours can be used in internal medicines such as tablets; capsules etc. or for external applications such as ointments, gel etc. These colours have to be prepared as per the methods and tests put forward by governing authorities. Any kind of lapse on following the guidelines can lead to low quality of products and sometimes lead to permanent problems for patients that can even prove fatal.

Better sales with colours

On the business side, colours affect sales figures too. For example, a tablet in yellow colour of a specific shape can be related to a brand which the patients can easily connect to. On the other hand, a white tablet in a commonly available shape gets lost among many other similar looking tablets in the market. The colour of the medicine gives it a distinct identity.

Certain colours such as natural colours are exempt from certification while other chemical-based colours need to be certified by pharmaceutical color manufacturers. Metal oxides, aluminium lakes and non-synthetics are pigments used in colours for pharmaceutical products. Water soluble colours are used in medicines for dispersion properties that help consume the medicine. Pharma colourants such as organic, inorganic or water-soluble are selected based on their properties.

Control of batch to batch colour variation is of utmost importance for pharmaceutical colors manufacturers. Any variation can lead to quality concerns in colour coating. Manufacturing of these colours depend on the uncompromising quality standards set by the governing authorities and varies from country to country.

What is the Difference? – Pigments vs Dyes

Ever wondered about the type of colours used in cosmetics. Based on the applications, cosmetic colours also known as colourant are classified into two types, dyes and pigments. Understanding the difference between cosmetic dyes and cosmetic pigments helps to choose the appropriate colourant for cosmetic manufacturers.

How different is the colouring process for cosmetic dyes and cosmetic pigments?

• The process of dyeing involves physical and chemical reactions. Pigments are colour particles that require a binding or dispersion agent to bind to the surface of the material to be coloured.
• Dyes have molecules that are smaller than pigment particles.
• Dyes are soluble in water and in certain types of solvents such as oil, alcohol, glycerine etc. Pigments are insoluble in water and many other solvents.
• Molecular study is required in choosing the dyes while it is not required in pigments. Crystal structure, particle properties, surface area & absorption, binder type and application are considered in the selection process of a pigment. Quantity of pigment to be used also makes a difference for products.

Key facts about Dyes

• Dyes can be organic or synthetic dyes. Organic dyes are obtained from natural resources.
• Brighter colours can be obtained through dyes.
• Dyes showcase poor fastness to light.
• Special-purpose Dyes can have properties such as heat-resistance, UV resistance, weather resistance etc.

Key facts about Cosmetic Pigments

• Cosmetic pigments are further divided into organic pigments and inorganic pigments. Organic pigments are of three types namely- Lakes, toners and true pigments. Inorganic pigments are made of different chemical types such as chromium dioxides, iron oxides, ultramarines etc.
• Organic pigments have high color strength while inorganic ones have weak colour strength.
• Bright shades can be obtained through organic pigments compared to dull shades by inorganic pigments.

Dyes are generally used for making hair dyes, lipsticks etc. Pigments such as oxides and more are used for giving vibrant shades to nail paints, blushes, face powders etc. In certain cases, it is possible to combine pigments and dyes for specific applications. Specific dyes and pigments are approved or restricted for use in cosmetics for application in certain body areas or cosmetic types. Dyes and Pigment manufacturers conduct tests and follow international standards with the prescribed amount of ingredients to ensure safe application of the colourants.

Natural colours derived from natural sources do not need to be certified in most places across the world. Synthetic organic colours have to be certified though.
