Question	Answer
marketed in response to the first ozone depletion scare;	Pumps
(PUMPS) 1 emollients incorporated: 2 (retard the possible crystallization of the active)	. 1 Volatile Silicone, PPG-15 stearyl ether 2 PPG-15 stearyl ether
(PUMPS) an enhanced effectiveness aluminium chlorohydrate with ESTABLISHED COMPATIBILITY IN AQUEOUS-BASED SYSTEMS	REACH 501 active
The original patent specified the composition comprising an anti-perspirant salt, a bulking agent, a synthetic polymer gum non-volatile organic liquid liquefied hydrocarbon or halocarbon propellant	Aerosols
(AEROSOLS) 1 Reduces Insolubility and staining	. 1 volatile silicones (replacing isopropyl myristate)
an increase in efficiency of 30-40% is achieved, by replacing standard ACH with the enhanced efficiency grade in the above. solves antiperspirant efficiency when compared to non-aerosol dispensers	enhanced efficiency aluminium chlorohydrate
formulations containing ratios of product concentrate to hydrocarbon propellant of 1.5:1 (60:40). activated ACH level of 20% HIGHER LEVELS OF SILICONE OILS SPRAY RATES are REDUCED to 0.35-0.45 g/s	CONCENTRATED AEROSOL
recent product form introduced in 1993 - ANHYDROUS CREAMS; - powder active is dispersed in volatile and non-volatile fluids; -the entire composition is then FORMED into a SEMI-SOLID using thickening agents; -rub in quickly, are NON-TACKY, leave LITTLE OR NO VISIBLE residue on skin - deliver high levels of antiperspirant protection	SOFTSOLIDS
-WATER-IN-OIL EMULSIONS -refractive indices of the continuous and dispersed phases are identically matched. - SILICONE SURFACTANT REQUIRED to achieve STABILITY	CLEARGELS
FRAGRANCE 1 Experience has shown that __ are unstable 2 are stable	. 1 phenol-containing materials, natural oils, and unsaturated alcohols and aldehydes 2 ketones, nitriles, esters, saturated aldehydes, and saturated primary and secondary alcohols
It is of interest to note that __ fragrances dominate the antiperspirant market	aldehydic
STAINING BY ANTIPERSPIRANTS 1 __ fabrics are most susceptible to stain formation, 2 significantly less susceptible fabrics	. 1 Cotton and linen 2 polyester, nylon and wool
