Evaluation Methods for Conditioned Hair

E. Desmond Goddard, James V. Gruber
In an effort to make the term “conditioner” more meaningful, Robbins (1) has proposed the following narrow definition: “A hair conditioner is an ingredient or a product, that when applied to hair in its recommended use procedure and concentration improves the combability relative to appropriate controls.” However, polymeric compounds are being incorporated into cosmetic products for a number of purposes with the major goal of improving the “condition” of hair, which in this discussion includes in the broadest terms its appearance and manageability. Properties such as combability, flyaway, body and curl retention, to name just a few, are affected by the deposition of polymers on the hair surface. The question as to what extent polymeric conditioners with their high molecular weight are deposited strictly on the fiber surface or can penetrate into the cuticula or even beyond it into the cortex surprisingly has been answered in the affirmative, at least for long treatment times. Goddard et al. (2), using radioactively labeled cationic quaternized cellulose derivatives, have shown such penetration for the well-known Polymer JR compounds. While the major effects of polymer-containing treatment formulations are associated with the modification of surface properties, there is nevertheless recent evidence from work at TRI/Princeton (3,4) that at least intercuticular cohesion is affected by such treatments.
Polymers as Conditioning Agents for Hair and Skin
Published in Randy Schueller, Perry Romanowski, Conditioning Agents for Hair and Skin, 2020
This review has attempted to trace the use of cationic and noncationic polymers in hair and skin conditioning. As styling trends required more chemical and thermal treatments, such as perming, coloring, and blow-drying, conditioning treatments became more important. Modern conditioners are designed to provide one or more of the following functions: provide ease of wet and dry combing; smooth, seal, and realign damaged areas of the hair shaft; minimize porosity; impart sheen and a silken feel to the hair; provide some protection against thermal and mechanical damage; moisturize; add volume and body; and eliminate static electricity. Today, polymers offer the consumer easier, more convenient, and more versatile styling and grooming than at any time in the past.
Biopolymer Films Based on the Blends of Silk Fibroin and Collagen for Applications in Hair Care Cosmetics

The conditioner is used to coat the hair with a thin film in order to protect it and provides desirable look and feel. Conditioners repair hair damage and make the hair easier to comb, prevent flyaway, add feel, shine, and softness. Conditioners, which typically repair the hair surface, respectively, have a distinct effect on its mechanical properties as well. To meet the needs of consumers, many ingredients, such as synthetic and natural polymers are added to conditioners [5, 6].
Treatment of Real Cosmetic Effluent Resulting from the Manufacture of Hair Conditioners by Reduction Degradation, Adsorption and the Fenton Reaction

The hair conditioners contain cationic surfactants, long chain fatty acids and some lipid compounds. The main surfactants of a hair conditioner include the ammonium quaternary and the polyquaterium, which have a structure with a positive charge in nitrogen. These structures behave as cations with regard to metallic iron, which makes its adsorption possible at pH 7.0 by means of this adsorbent layer (Colombera 2004; Galembeck and Csordas 2009).
