Not only do you receive statistical data – our court-proof expert opinions reliably prove the claims of your product.
Absolute confidentiality has been the foundation of our cooperation with our clients for more than five decades.
Quality, know-how and competence in cosmetics make us a globally valued partner.
Only at Schrader will you find interdisciplinary know-how in research, development, testing and analytics for the decisive difference in competition.
In the hair workspace, application studies of all kinds are carried out combined with dermatological and ophthalmological control.
Independent galenic application technology for the cosmetics industry has been our task for 50 years. Within the scope of galenics, we develop new, individually tailored formulations for any kind of cosmetics for skin care and hair care – especially also sun protection products as well as natural cosmetics.
The analytical work area stands for chemical-analytical investigations of cosmetics. The focus of the department’s work is on the quality assurance of cosmetic products.
The field of research is the basis of many innovations and novelties, by which the Institut Dr. Schrader distinguishes and recommends itself again and again.
In order to meet the ever-increasing demands of the Asian market, Institute Dr. Schrader International GmbH was founded in 2004.
Institute Dr. Schrader – nucleus of globally applied procedures.
New methods that are the basis for determining the effectiveness of and tolerance to cosmetic products.
Five decades of developing ideas and principle concepts for measuring skin- and hair-physiological parameters, which have been adopted worldwide and matured into today´s standard test methods.
Our best-known developments:
The internationally recognized methodology for determining the sun protection factor according to ISO 24444 is considered the "gold standard". The testing is invasive, time consuming and complex.
The "Alt-SPF" project is currently the largest interlaboratory test in the field of sun protection testing and evaluates non-invasive and resource-saving alternative methods.
We are participating in the review of the non-invasive in vivo methodology - HDRS (Hybrid Diffuse Reflectance Spectroscopy). The method was developed in-house, describing for the first time a reliable alternative test method for SPF and UVA-PF determination that takes into account the interaction of the sunscreen with the skin. ...more
A new in-vivo method for sun protection testing finally on the threshold of ISO introduction
Right from the beginning of the first ideas, Institut Dr. Schrader Hautphysiologie is part of the ALT-SPF Consortium for developing alternative methods regarding SPF determination, including the Hybrid Diffuse Reflectance Spectroscopy (HDRS) method which is currently an ISO draft standard.
Digital volume measurement is used to determine hair volume following the application of hairstyling or hair care products. For this test, hair strands are treated differently depending on the type of product.
A light source is used to cast a shadow of the hair strands, which is measured digitally before and after treatment (possibly several treatments). The exact volume of the hair strand is determined by rotating the strand and further image analysis.
Modern cosmetics with efficacy claims like “Anti-Ageing” or “Oxidative Protection” are among others complex mixtures of UV filters and antioxidants.
Proof of efficacy must be obtained with sound scientific methods for such claims. Sunlight (UV radiation) is the main cause of premature skin aging (photo-ageing), primarily due to generation of free radicals and the oxidative stress associated with them. The biggest challenge in claim support is non-invasive yet sensitive measurement of oxidative stress on subjects.
The institutes Dr. Schrader participate in the DGK advanced training course on April 26 and 27: The hair and its treatment.
A special highlight proved to be the demonstration and explanation of relevant test methods and application tests by Dr. Jutta Quadflieg, Head of Hair Physiology, Institut Dr. Schrader Creachem GmbH.
