CHLUMICARE\u00ae HAP \u2014 4-Hydroxyacetophenone<\/h2>\n

CHLUMICARE\u00ae HAP identifies 4-hydroxyacetophenone, also called p-hydroxyacetophenone, within the Longchang Chemical specialty cosmetic ingredient range. The material is positioned for professional evaluation in formulation antioxidant work and in the development of a complete cosmetic preservation package.<\/p>\n

Product identification<\/h3>\n\n\n\n\n\n\n
Product model<\/th>\nCHLUMICARE\u00ae HAP<\/td>\n<\/tr>\n
Nome chimico<\/th>\n4-Hydroxyacetophenone<\/td>\n<\/tr>\n
Alternative name<\/th>\np-Hydroxyacetophenone<\/td>\n<\/tr>\n
Numero CAS<\/th>\n99-93-4<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Formulation positioning<\/h3>\n

HAP can be considered during ingredient screening for cosmetic formulas where antioxidant functionality or preservation-package compatibility is being investigated. Its role should be defined using the complete ingredient system, packaging and intended conditions of use. Performance cannot be established from the presence of one ingredient alone.<\/p>\n

This page does not identify HAP as a universally authorized standalone preservative. Confirm the applicable ingredient classification and use conditions for the destination market. Assess the complete preservation system with appropriate finished-product microbiological testing; ingredient selection does not replace that assessment.<\/p>\n

Quality and technical review<\/h3>\n

No universal addition rate, assay, solubility or processing specification is stated here. Obtain the current specification for the offered material and confirm compatibility and stability in the intended base before scale-up. The listing makes no antiseptic, therapeutic or anti-inflammatory claim.<\/p>\n

For a technical enquiry, provide Longchang Chemical with model HAP, CAS 99-93-4, your product format and required raw-material quality criteria. Request the current TDS, SDS and available lot-specific COA. Use those documents, together with your formulation results, to establish material acceptance, handling conditions and suitability for the proposed commercial application.<\/p>\n
