AND FIRST HALF SALES AND EARNINGS

NORTHFIELD, Illinois, July 29, 2008 -- Stepan Company (NYSE: SCL) today reported second quarter results for the period ended June 30, 2008.

SUMMARY

	Three Months Ended June 30			Six Months Ended June 30
($ in thousands)	2008	2007	% Change	2008	2007	% Change
Net Sales	$420,399	$336,156	+ 25	$801,850	$649,160	+ 24

Earnings per Diluted Share	$0.93	$0.47	+ 98	$1.79	$1.03	+ 74

SECOND QUARTER RESULTS

Net income for the quarter was $9.8 million, or $0.93 per diluted share, compared to $4.7 million, or $0.47 per diluted share, a year ago. Gross profit rose by $11.7 million, or 31 percent, on flat volume. The surfactant and polymer segments both recorded improved gross profit. Surfactant gross profit grew by $9.8 million (42 percent) on improved customer and product mix, as volume declined by one percent. Polymer gross profit rose by $2.5 million (20 percent) on improved margins and a five percent increase in volume.

Pretax income of $14.5 million was up $7.0 million, or 95 percent. Following is a reconciliation of pretax income excluding certain significant quarterly and year-to-date items:

	Three Months Ended June 30		Six Months Ended June 30
($ in thousands)	2008	2007	2008	2007
Reported Pretax Income	$14,510	$7,459	$27,307	$15,539
(Gain) on Sale of Product Line	-	(4,290)	-	(4,290)
Goodwill Impairment Charge	-	3,467	-	3,467
Deferred Compensation:
Administration Expense	2,466	1,995	3,140	631
Other - Mutual Fund (Gain) / Loss	(226)	-	1,001	-
Non GAAP Pretax Income Excluding Above Items	$16,750	$8,631	$31,448	$15,347

Deferred compensation expense was $2.5 million compared to $2.0 million in the year ago quarter. The accounting requirement for the Company's deferred compensation plan results in expense when the price of Stepan Company stock or mutual funds held for the plan rise and income when they decline. Stepan Company common share price rose by $7.39 per share during the quarter.

Net sales increased 25 percent during the quarter, primarily due to higher selling prices (21 percent) and the favorable impact of foreign currency translation (four percent). Sales volume was flat. Rising crude oil derivative prices and the inflationary impact across most chemical feedstocks led to the higher selling prices.

YEAR-TO-DATE RESULTS

Net income for the six month period was $18.5 million, or $1.79 per diluted share, compared to $10.4 million, or $1.03 per diluted share, last year. Gross profit increased $22.8 million, or 31 percent, on a one percent decline in volume. The improved results were led by a $21.2 million (46 percent) increase in surfactant gross profit. Improved customer and product mix, as well as recovery of fabric softener margins led to the improvement in surfactant gross profit. Surfactant volumes declined by two percent. Polymer gross profit grew by $1.6 million (seven percent) due to a four percent increase in volume.

Pretax income rose $11.8 million (76 percent) due to the improved gross profit, partially offset by an $8.5 million (16 percent) increase in operating expenses largely attributable to a $2.5 million increase in deferred compensation expense. See the operating expense discussion below.

Year-to-date net sales increased 24 percent due to higher selling prices (21 percent) and foreign translation impact (four percent), while volume declines reduced net sales by one percent.

SEGMENT RESULTS

	Three Months Ended June 30			Six Months Ended June 30
($ in thousands)	2008	2007	% Change	2008	2007	% Change
Net Sales
Surfactants	$308,012	$242,765	+ 27	$598,336	$479,241	+ 25
Polymers	103,088	84,892	+ 21	183,924	153,574	+ 20
Specialty Products	9,299	8,499	+ 9	19,590	16,345	+ 20
Total Net Sales	$420,399	$336,156	+ 25	$801,850	$649,160	+ 24

Surfactant gross profit increased $9.8 million, or 42 percent, during the quarter on volume that declined by one percent. The increase reflects continued improvement in customer and product mix, as well as recovery of higher raw material costs in selling prices. Fabric softener margins recovered from erosion during 2007. Sales of higher value added surfactants in the distributor market, agricultural and oilfield drilling products contributed to the improved gross profit. The slight decline in volume was due to lower personal care sales volume due to a customer reformulation from low active to high active products that result in lower volumes. Commodity laundry and fabric softener volumes improved. Biodiesel continues to generate a small profit versus year ago losses due to the higher diesel prices and our use of lower cost tallow as a feedstock in conjunction with soybean oil. Surfactants represent 75 percent of Company sales.

Polymer gross profit grew by $2.5 million, or 20 percent, as volume grew by five percent. The Company's polyol product experienced a 13 percent increase in volume and represented most of the polymer segment improvement in profit. Stepan's polyol is used primarily in rigid foam insulation for commercial roofing. The majority of this market is for replacement roofs versus new construction. This market remains strong, in part due to the desire for greater energy savings achieved from increased insulation. The polymer segment experienced lower sales volume of phthalic anhydride (PA) due to the decline in demand from the automotive, recreational vehicles and boating industries, where PA is used in unsaturated polyester resins for plastic and composite materials. PA profit declined on the lower volume. Polymer sales represent 23 percent of Company sales.

Specialty Products gross profit remained unchanged for the quarter as improved pharmaceutical volume was offset by weaker food ingredient volume. Specialty Products represent two percent of Company sales.

Total	$32,414	$28,578	+ 13	$61,394	$52,855	+ 16

The major contributors to the increase in all categories of operating expenses were incentive based compensation charges and higher foreign operating expenses due to the translation effect against the weaker U.S. dollar. Incentive based compensation includes stock awards (based on long term incentive targets), bonuses and profit sharing. The quarter and year-to-date impact of these items on the total operating expense increase is summarized below:

	Operating Expense Increase
	Three Months Ended June 30	Six Months Ended June 30
Incentive Based Compensation	$1,182	$2,286
Foreign Translation Effect	839	1,636
Deferred Compensation	471	2,509
Other	1,344	2,108
Total Operating Expense Increase	$3,836	$8,539

The remaining "Other" operating expense increases represent a five and four percent increase for the quarter and year-to-date periods, respectively.

OTHER INCOME AND EXPENSE

Interest expense grew by two percent for the quarter and six month period due to higher average debt levels brought about by higher working capital requirements. Working capital requirements have grown due to increased sales and the impact of rising raw material costs. The loss from our equity in the Philippine joint venture increased due to production outages and reliability of raw material supply.

Included in other, net expense on the income statement is $0.2 million of income for the quarter and a $1.0 million loss year-to-date on mutual fund investments held for our deferred compensation plan. In January 2008, the Company adopted new accounting rule Statement of Financial Accounting Standards No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, which allows for the marking to market of financial instruments such as these in the income statement, which were previously recorded in accumulated other comprehensive income in the stockholders' equity section of the balance sheet.

PROVISION FOR INCOME TAXES

The effective tax rate declined to 32.8 percent for the quarter compared to 37.6 percent a year ago. The decrease in the effective tax rate was primarily due to the recording of Stepan U.K. goodwill impairment during the prior year for which no tax benefit was realized.

OUTLOOK

"We are pleased we were able to deliver strong second quarter earnings and build on the momentum we established in the first quarter," said F. Quinn Stepan, Jr., President and Chief Executive Officer. Net income was up 106 percent for the quarter and 78 percent year-to-date. Profitability of our global surfactant business continued to benefit from an improved customer and product mix, reduced outsourcing and our restructuring efforts, as well as recaptured margins. Our polymer results were driven by global polyol volumes as high energy prices led to increased demand for insulation. Phthalic anhydride sales were down due to the slow economy. During the fourth quarter of 2008, our phthalic anhydride and polyol manufacturing facilities at Millsdale will undergo their triennial maintenance turnaround. We expect slightly higher maintenance and outsourcing costs in the fourth quarter. "While we remain concerned about the economic environment, we believe our improved profitability is sustainable," said Mr. Stepan.
