CONTROLE DE QUALIDADE EM UMA INDÚSTRIA DE COSMÉTICOS CAPILARES: RELATO DE EXPERIÊNCIA EM ESTÁGIO SUPERVISIONADO

Abstract

The Personal Hygiene, Perfumery, and Cosmetics (HPPC) sector is among the most dynamic industrial segments in Brazil, characterized by constant product innovation and strict regulatory requirements imposed by health authorities. In this context, quality control plays a strategic role in ensuring the safety, efficacy, and compliance of marketed hair cosmetics products. This work aims to describe and discuss the activities developed in the Quality Control sector of a hair cosmetics industry, relating the observed practices to the technical and regulatory foundations that guide the quality management system in the Personal Hygiene, Perfumery and Cosmetics sector. This is an experience report based on a supervised internship, structured from the practical experience of the sector's analytical, documentary and operational routines. The activities encompassed environmental monitoring and analytical equipment calibration, physical-chemical and organoleptic analyses (including the determination of pH, viscosity, density, appearance, color and odor), microbiological analyses of finished products, raw materials, potable water and production equipment, daily physical-chemical monitoring of supply water, incoming control of raw materials and packaging, document management, and solid and biological waste management. Activities observed in other areas of the production sector were also described, including batch manipulation in mixing reactors, filling, labeling, coding and dispatch of finished products. The practices described were analyzed in light of Resolution RDC No. 48/2013, which establishes Good Manufacturing Practices for the sector, RDC No. 907/2024, which consolidates the regularization of products and microbiological control parameters, and Ordinance GM/MS No. 888/2021, which defines water potability standards. The results showed that quality control constitutes an integrated and transversal system that permeates all stages of the production process, with documentation and traceability being central elements for regulatory compliance and the safety of the final product. It is concluded that the experience provided a comprehensive and well-founded understanding of the practices that support quality in the hair cosmetics industry, demonstrating the relevance of the chemical engineer's role in the context of industrial quality control.
