Protection of hair against odor pollution
Today, the term “Exposome” is used to describe all environmental factors that can have an impact on the skin and its appendages. Solar radiation, air pollution (both outdoor and indoor) and cigarette smoke have long been known to dull the complexion, alter the firmness of the skin, and accelerate the appearance of wrinkles and pigmentary disorders.
In the case of hair, air pollution weakens the hair fibres, and the deposit of particles makes the hair dull and brittle. But another type of consequence can also be mentioned: olfactory pollution. Hair is known to catch odours very easily, whether they are good or bad. After all, who has never complained about having their hair smell like tobacco, fumes or fried food after spending time in "polluted" environments?
To combat these "bad smells", Eurofins Cosmetics & Personal Care has developed a new approach that allows you to evaluate the "anti-odour" effectiveness of hair products (shampoos, conditioners, leave-ins or mists). Hair strands are treated before and after prolonged contact with odourant molecules (chosen according to your needs) and then our expert panel evaluates the neutralising effect of the product on odours in comparison to untreated strands.
New Service: Cleaning Validation Strategy
Avoiding possible residues and contaminants in products is of the utmost importance. The process of cleaning validation is one of the key steps to ensure safe cosmetic products.
Following the cross-contamination control reinforcement, regulatory authorities today require industries such as pharmaceutical, cosmetics, medical devices, etc., to take a risk-based approach for their validation strategy and new acceptance criteria.
With Eurofins, a cleaning validation serves to prove that defined cleaning and disinfection measures of production sites and associated equipment are suitable and sufficient regarding the production of harmless products, following the steps below:
- Microbiology testing and consulting
- Analytical testing: rinse-water analysis, swab analyses
- Audit, consulting: assessment of your cleaning and validation strategies, action plan to fill gaps, a training plan
We can help you to use the same production vessel for different products, ensuring that no particles, residues and contaminants will remain from one production to another.
Expansion of oral care assessment
Measurement and assessment of denture plaque can provide valuable information regarding an individual's oral health status and the assessment of new oral treatments or oral products.
This evaluation involves the use of several oral indices to describe the health status of hard and soft tissues by evaluating the following indices:
- Evaluation of the plaque Index (PI)
The effect on the dental plaque is assessed objectively and semi-quantitatively by clinical score using the plaque index Silness & Loe. The Silness & Loe index assesses the thickness of the plaque deposited on the surface of the gingival border of all teeth present in the mouth. Plaque developers are not used; it is determined by passing an explorer over the surface of the tooth and examining the plaque probe tip.
- Evaluation of the gingival index (GI)
The gingival index described by Loe & Silness, measures the severity of the inflammatory response around all the teeth present in the mouth by determining the quantity, quality, severity and location. Each tooth is divided into 4 gingival units (vestibular, lingual, distal, and mesial).
- Sulcus Bleeding Index (SBI)
The measurements are performed according to the Sulcus Bleeding Index (SBI) described by Muhlemann and Son.
These indices complement an already well-developed clinical offering for the evaluation of oral products:
Teeth Whitening, Anti-Plaque, Anti-Tartar, Teeth Hypersensitivity, Anti-Bacterial (Mouth), Anti-Halitosis.
