Skin care & Toiletries

Sensorial-analysis-skin-care_1Sensory impressions of cosmetic products play an essential role in influencing the consumer’s product selection process and re-purchase behavior. Therefore it is essential to identify and quantify the product’s sensory properties during application and use.
Whether you need to evaluate the influence of a new manufacture procedure; evaluate the influence of changing a raw material or packaging; define the sensory attributes of a target product for new product development; document a product’s attributes before a consumer test to help in the Sensorial-analysis-skin-care_2selection of attributes to be included in the questionnaire; track a product’s sensory changes over time; etc; inovapotek provides sensorial analysis tests namely:

  • Discriminative tests (such us Triangle test)
  • Affective tests,
  • Descriptive tests, involving detection (discrimination) & description of qualitative and quantitative sensory aspects of a product by trained panels.

Our trained panelists are able to detect & describe the perceived qualitative sensory attributes of a sample and to differentiate & rate the quantitative or intensity aspects of a sample according to ASTM E1490-11 (Standard Guide for Two Sensory Descriptive Analysis Approaches for Skin Creams and Lotions).

Several attributes can be analyzed such us:

  • Appearance evaluation: amount of spread, thickness, ease of dispensing;
  • Pick-up evaluation: Amount of peaking, firmness, stickiness;
  • Rub-out evaluation: spreadability, absorbency, thickness;
  • After-feel evaluation: slipperiness, moisture, stickiness, greasiness, oiliness, silkiness, soft finish, etc;

Hair care 

Sensorial-analysis-hair-careThe hair-care industry needs to quantitatively assess the objective sensory attributes of hair-care products, including the sensory properties involved in dispensing a product, in product application and the sensory features provided to wet and dry hair. These attributes can then be used to define product performance and to provide direction in product formulation, research guidance testing, and claim substantiation.

Sensorial analysis of hair-care products can be performed using hair tresses or subjects (half and whole heads). If using hair tresses evaluation, a panel of trained assessors treats hair swatches with the shampoo products and evaluates the appearance, product pick-up, application, foaming, and wet hair and dry hair attributes of the shampoo. Evaluations using live subjects are typically performed in a salon-type setting and most of the attributes are similar to those evaluated on hair tresses.

Inovapotek performs sensorial analysis for hair care according to ASTM E2082 – 12 – Standard Guide for Descriptive Analysis of Shampoo Performance. Although this guide is specific to shampoos, the procedures should be applicable to most hair-care products.

Several attributes can be analyzed such us:

  • Appearance evaluation: firmness, integrity of shape, transparency, pearlescence;
  • Pick-up evaluation: firmness, stickiness;
  • Application and foam characteristics: ease of spreading, speed to foam, amount of foam, cushion of foam, bubble size, ease of rinsing;
  • Wet hair characteristics: ease of detangling, force to comb, slipperiness, residue (greasy, oily);
  • Dry hair characteristics: ease of detangling, force to comb, slipperiness, residue (greasy, oily), static, etc.;
