 Exhibit 10.1 

SEPARATION AGREEMENT AND RELEASE 

This Separation Agreement and Release (“Agreement”), dated as of August 15, 2017, is entered into by SCOTT C.
MASON (“Employee”) and STEPAN COMPANY (the “Company”) for the purpose of separating Employee from the Company under mutually agreeable terms. The parties agree as follows: 

1. Employment Status and Final Pay. 

(a) Employee’s employment with the Company and all of its affiliates shall terminate on August 15, 2017 (the “Separation
Date”). Effective as of the Separation Date, Employee shall be deemed to have resigned from all offices, appointments, and committees associated with the Company that he then holds. Effective on the Separation Date, Employee will
cease all work on behalf of the Company and will not represent to any third party that he represents or has authority to act on behalf of the Company. Employee will promptly sign all appropriate documentation requested by the Company to reflect or
facilitate such termination and resignation. 
 (b) Employee shall be paid all wages or salary owing through the Separation Date and a lump
sum payment for any unused vacation days earned through the Separation Date in accordance with applicable law. Employee’s group insurance coverage shall end on August 31, 2017, subject to all terms and conditions of the applicable
plans. Thereafter, Employee’s group insurance coverage may be continued on a voluntary basis, at Employee’s cost, under COBRA and as provided by the terms and conditions of each such plan. Employee acknowledges and agrees that, except as
set forth in paragraph 2 below and this paragraph 1(b), as of the Separation Date, Employee is not entitled to any further wages (including, without limitation, bonuses or incentive compensation), perquisites, other benefits, stock options, stock
appreciation rights or other equity-based or cash-based awards from the Company. 
 (c) Employee shall have the right, in his discretion, to
purchase from the Company the Company-provided automobile currently being used by Employee in connection with his employment with the Company at a purchase price and on such other terms and conditions as may be determined by the Company. If Employee
elects to purchase the automobile, Employee must advise the Company’s Vice President, Human Resources of his intent to do so on or before the Separation Date. 

2. Release; Consideration for Release. In consideration of the Company’s agreement to pay or provide Employee the payments
and other benefits set forth in this paragraph 2, Employee agrees that, on or within the twenty-one (21) day period following the Separation Date, Employee will execute and deliver to the Company a
Release of Claims in the form attached hereto as Exhibit A (the “Release”). Subject to and conditioned upon (i) Employee’s timely execution and delivery to the Company of the Release and Employee’s non-revocation of the Release during the applicable revocation period and (ii) Employee’s continued compliance with the terms and conditions of this Agreement (including, without limitation,
paragraphs 4, 5 and 6 hereof), Employee will be paid or provided with the following: 

  
 Page 1 of 8 

 (a) The Company shall pay Employee an aggregate amount equal to $397,232, less applicable taxes
and withholding (the “Cash Payment”), payable in two equal installments as follows: fifty percent (50%) of the Cash Payment shall be paid to Employee not later than the second regular payroll date occurring on or after the effective date
of the Release and fifty percent (50%) of the Cash Payment shall be paid to Employee on the first regular payroll date occurring on or after the six (6) month anniversary of the Separation Date. 

(b) Subject to and in accordance with the terms and conditions of the Stepan Company Management Incentive Plan (the “MIP”), and
consistent with Section 2.1 of the MIP, Employee shall remain eligible to receive a prorated portion constituting 62.5% of any 2017 incentive award that would otherwise have been payable to him under the MIP had he remained employed with the
Company through December 31, 2017. The Company and Employee acknowledge and agree that for purposes of the MIP, the termination of Employee’s employment with the Company shall constitute a retirement. 

(c) Subject to and in accordance with the terms and conditions of the Stepan Company Savings and Investment Retirement Plan (the
“SIRP”), Employee shall remain eligible to receive a prorated portion constituting 62.5% of any 2017 Profit Sharing award that would otherwise have been payable to him had he remained employed with the Company through December 31,
2017. The Company and Employee acknowledge and agree that for purposes of the SIRP, the termination of Employee’s employment with the Company shall constitute a retirement. 

(d) Employee’s outstanding stock option and stock appreciation right awards listed on Exhibit B attached hereto will become vested
and exercisable in full as of the day immediately preceding the Separation Date, and shall otherwise be treated in accordance with the terms and conditions of the governing plan document and the applicable award agreement thereunder. 

(e) Employee’s stock option, stock appreciation right and performance share awards listed on Exhibit C attached hereto shall be
treated in accordance with the terms and conditions of the governing plan document and the applicable award agreement thereunder. The Company and Employee acknowledge and agree that for purposes of the awards set forth on Exhibits B and C
hereto, the termination of Employee’s employment with the Company shall constitute a retirement. 
 3. Return of Equipment
and Records. On or prior to the Separation Date, Employee shall (i) return to the Company (a) all keys, access cards, identification badges, telephone calling cards, credit cards, mobile phones and other telecommunication
equipment, computer hardware and software, printers, projectors, Company-provided automobile (unless Employee exercises the right to purchase as set forth in paragraph 1(c)) and other property and equipment that Employee received in connection with
Employee’s employment with the Company and (b) the originals and all copies of all records and other documents (including information stored on CDs, USB drives, hard drives, or any other medium) that Employee received, prepared or
helped prepare in connection with Employee’s employment with the Company, other than documents 

  
 Page 2 of 8 

 
Employee sent and received relating solely to Employee’s own compensation and benefits and documents that are accessible to the public, and (ii) delete from any personal computer
or personal electronic storage any of the information he is obligated to return under this paragraph. On or prior to the Separation Date, the Company shall provide to Employee all of his personal property then in the Company’s
custody. 
 4. Non-Disparagement; References and Future Communication. 

(a) Employee will not, directly or indirectly, disparage the Company or its affiliates or subsidiaries or any of their employees, officers,
and directors (including former employees, officers and directors) by any means or in any medium. Employee will not disclose to any third party any personal information about any director, manager, officer, employee or agent of the Company or
any of its affiliates or subsidiaries. Further, Employee will not take any action or make any statement, whether publicly or privately, verbally or in writing, or cause or permit to be published under Employee’s name, any other name or
anonymously, or otherwise communicate by any means, any statement, observation or opinion that is critical of, impugns or in any way negatively reflects upon or would tend to cause damage to the business, reputation, goodwill, brands, names,
products or services of the Company or its affiliates or subsidiaries, or to any of their respective officers, directors or employees. 

(b) Employee will refer requests for employment references only to the Company’s Chief Executive Officer. The Company’s Chief
Executive Officer is the only person authorized to respond for the Company. The Company’s Chief Executive Officer will provide only Employee’s dates of employment and positions held. If requested, the Company’s Chief Executive Officer
will also confirm Employee’s final salary. The Company is not responsible for any reference or other information provided by any other person employed by or otherwise associated with the Company who Employee or a third party may contact,
whether or not the information is provided using the Company’s communication systems or letterhead or the person purports to speak on behalf of the Company. 

(c) Following the Separation Date, Employee will not visit any of the Company’s facilities without prior written approval from the
Company’s General Counsel. Employee will not contact any current employee of the Company during regular business hours at his/her place of work; provided, however, that Employee may contact the Company’s Director of Corporate Human
Resources at any time to discuss post-termination benefits or other employment related issues, and may contact the Company’s General Counsel at any time for any other reason. In the event that Employee has a business reason for any such contact
with a Stepan employee, he must seek written authorization from the VP, Human Resources. For avoidance of doubt, this provision shall not affect any common law or contractual duty or obligation owed by Employee, including Employee’s obligation
to cooperate with the Company and its legal counsel as specified in paragraph 5 below. 

  
 Page 3 of 8 

 5. Cooperation. For a period of five (5) years from the date of execution of
this Agreement, Employee agrees to cooperate fully with the Company and its legal counsel with respect to any matter (including any litigation, investigation or governmental proceeding) which relates to Employee’s employment at Company or any
topic related to the supply chain business of the Company, including matters with which the Employee was involved or aware, directly or indirectly, during Employee’s employment with the Company. Such cooperation may include appearing from
time to time at locations within a reasonable commuting distance from Employee’s residence for conferences and interviews and in general providing the Company’s officers and legal counsel with the full benefit of the Employee’s
knowledge with respect to any such matter. Employee agrees to render such cooperation in a timely fashion and at such times as may be mutually agreeable to the parties. Employee agrees that if he is named individually as a defendant or witness in
any lawsuit as a result of his employment with the Company, or if Employee receives a subpoena in the course of any litigation or government investigation, Employee will immediately provide the Company with a copy of the subpoena or summons and
complaint in such matter, except to the extent prohibited by law. 
 6. Restrictive Covenants. 

(a) Employee acknowledges that Employee’s employment with the Company has permitted Employee access to confidential proprietary
information regarding the Company’s operations that has been created, discovered, developed, acquired, or otherwise become known to the Company, which information is disclosed on a need to know basis and has commercial value to the Company
and/or a competitor of the Company (“Confidential Information”). This Confidential Information includes, but is not limited to, business plans and strategies; technological and operational improvements; marketing plans and
strategies; non-public financial information; legal and compliance matters; and other information disclosed to Employee during his employment which is not public information. All such Confidential
Information will remain the sole property of the Company. At all times during and after the termination of Employee’s employment with the Company, Employee will keep all such Confidential Information in the strictest confidence and trust, and
will not disclose, transmit, or use in any way any such Confidential Information without the prior express written consent of the General Counsel or until such information enters the public domain through no fault of Employee. 

(b) The Employee Agreement, dated March 9, 2010, entered into by Employee (the “Employee Agreement”) will remain in full force
and effect and will be harmonized to the extent possible with this Agreement; provided, however, to the extent there are any irreconcilable differences between the Employee Agreement and this Agreement, it is the intent of the parties that the
agreement which provides the greatest protection to the Company will control. 
 (c) Employee agrees that during his employment and for a
period of twelve (12) months following the Separation Date, Employee will not, either directly or indirectly, for Employee or for any third party solicit, induce, recruit, or cause any other 

  
 Page 4 of 8 

 
person who is then employed by the Company to terminate his/her employment with the Company and will not solicit, induce, or encourage any Company Counterparty to terminate its relationship with
or transfer its business from the Company or its subsidiaries or affiliates. For purposes of this Agreement, “Counterparty” means (i) each customer, client, vendor, or other party doing business with the Company or its subsidiaries or
affiliates that Employee had business contacts with or obtained Confidential Information about at any time during his employment with the Company, and (ii) each prospective customer, client, vendor, or other party doing business with the
Company or its subsidiaries or affiliates that Employee had business contact with or knowledge about as part of a solicitation of business on behalf of the Company at any time during the two (2) year period prior to the Separation Date. 

(d) Employee further agrees that during his employment and for a period of twelve (12) months following the Separation Date, Employee
shall not directly or indirectly, own, manage, operate, join, control or participate in the ownership, management, operation or control of, or be connected or associated as a director, officer, employee, partner, consultant or otherwise with, any
business or organization which, directly or indirectly, competes with, or in any way interferes with, the Business. For the purposes of this paragraph 6(d), “Business” shall mean the manufacture, sale and distribution of surfactants,
polymers and specialty products that are currently manufactured, sold and distributed by the Company, or any product that is, or about which Employee has reasonable basis to believe is, within the scope of the Company’s business. 

(e) Employee’s covenants set forth in this Agreement shall continue to be binding on Employee notwithstanding the termination of
Employee’s employment with the Company. Such covenants shall be deemed and construed as separate agreements independent of any other provisions of this Agreement and any other agreement between the Company and Employee. The existence
of any claim or cause of action by Employee against the Company, unless predicated on this Agreement, shall not constitute a defense to the enforcement by the Company of any or all such covenants. It is expressly agreed that the remedy at law
for the breach of any such covenant is inadequate and injunctive relief and specific performance shall be available to prevent the breach or any threatened breach thereof. 

(f) If any term or provision of this paragraph and its subsections is deemed invalid or unenforceable by a court of competent jurisdiction, it
is the intent of the Company and Employee that such term or provision shall be deemed to be deleted and/or reformed to produce its nearest enforceable equivalent. In such an event, the validity of the remaining terms and provisions of this paragraph
and its subsections shall not be affected, and they shall operate in full force and effect as if the invalid term or provision were deleted and/or so reformed. 

7. Other Proceedings. Nothing in this Agreement or the Release is intended or shall be interpreted as prohibiting Employee from
filing a charge or complaint with any administrative or law enforcement office or agency, exercising any whistleblower rights (including applying for or receiving any award paid in connection with exercising

  
 Page 5 of 8 

 
such rights), providing testimony or information to, or participating in or cooperating with any administrative agency (including the NLRB, EEOC and SEC), governmental investigation or
inquiry, or testifying in any administrative or judicial proceeding. However, by signing this Agreement, Employee waives any right to recover damages or other personal relief based upon any charge, complaint, lawsuit, report, or other
proceeding brought by Employee or on Employee’s behalf by any third party, including any administrative or other governmental office or agency, based upon a claim that has been released pursuant to the Release. 

8. Reemployment. Employee will not seek to become re-employed by, or to perform services
for, the Company in any capacity, including as a consultant. Any application for re-employment or to perform services may be rejected without explanation pursuant to this paragraph. 

9. Valid Consideration; Breach of Agreement. Employee acknowledges and agrees that his right to receive and retain the payments
and benefits set forth in paragraph 2 is expressly conditioned upon his timely execution and non-revocation of the Release and his continued compliance with the terms and conditions of this Agreement. The
parties further acknowledge and agree that the mutual promises and covenants contained herein constitute good, valid and sufficient consideration for this Agreement and the Release. The parties further agree that in the event a court makes a final
determination that Employee has breached a material provision of this Agreement, Employee will return the Cash Payment, indemnify and hold the Company harmless of and from any all loss, cost, damage and expense (including reasonable
attorney’s fees and court costs) which the Company suffers, sustains, or incurs as a result of, in connection with or arising from the Employee’s material breach of this Agreement, or the efforts of the Company to enforce its
terms, and pay any other damages or relief the court may award; provided, however, that the rights of the Company under this paragraph are not intended to nor shall they be deemed to, constitute liquidated damages or an adequate remedy at law, in
whole or part, for a breach by Employee of a material provision, or to otherwise limit or preclude the Company from obtaining any monetary, injunctive, declaratory or other relief to which the Company is entitled. The term “material
provision” in this paragraph includes but is not limited to paragraphs 3, 4(a) and (c), 5 and 6. 
 10. No Admissions.
Nothing in this Agreement shall be construed as an admission that either party violated any law or otherwise engaged in any wrongful conduct. 

11. Choice of Law. Illinois law will govern the validity and interpretation of this Agreement without regard to Illinois’
conflicts of laws rules. Any litigation brought to enforce or interpret this Agreement or to decide any disputes between the parties, shall be brought exclusively in the state or federal courts located in Cook County, Illinois, and Employee
irrevocably consents to the exercise of personal jurisdiction over Employee by such courts. 

  
 Page 6 of 8 

 12. Severability. In the event any portion of this Agreement (other than the
Release) is determined to be invalid or unenforceable, the remaining portions of the Agreement will remain in full force and effect. 

13. Ambiguities. The parties acknowledge that each of them has had the opportunity to consult counsel (at their own expense) and
has participated in the negotiation and drafting of this Agreement. For purposes of interpreting this Agreement, each provision, paragraph, sentence and word will be deemed to have been jointly drafted by both parties. The parties intend for
this Agreement to be construed neutrally in accordance with the plain meaning of the language contained herein, and not presumptively construed against any actual or purported drafter of any specific language contained herein. 

14. Counterparts. This Agreement may be executed in one or more counterparts, each of which will be considered an original, and
all of which taken together will be considered one and the same instrument. 
 15. Entire Agreement. Employee
acknowledges that no promises or representations other than those set forth in this Agreement have been made to Employee to induce Employee to sign this Agreement, and that Employee only has relied on promises expressly stated herein. This Agreement
(including the Release) constitutes the entire agreement between Employee and the Company. This Agreement may not be modified except by a writing signed by both Employee and a duly authorized representative of the Company. 

16. No Additional Benefits. Employee acknowledges that, except as specifically set forth in this Agreement or with respect to
any rights vested as of the Separation Date to benefits under any Company-sponsored retirement, deferred compensation or group welfare benefit plan, Employee is not entitled to any compensation, severance benefits, vacation pay, bonuses, incentive
payments, employee benefits, attorney’s fees or other consideration from the Company. Employee explicitly acknowledges and agrees that he does not hold, or have any rights with respect to, any Company equity-based awards other than those listed
on Exhibits B and C attached hereto. 
 17. Notices. Any communication required or permitted to be given under this
Agreement will be sufficient if in writing and delivered personally, by commercial messenger service, by confirmed electronic mail, or by U.S. registered or certified mail, postage paid, return receipt requested to the addresses below or to such
other address as either party may designate by written notice to the other. 
 If to Employee, at Employee’s address as set forth in
the books and records of the Company.

 18. Knowing and Voluntary Agreement. Employee acknowledges that: (a) Employee
has read and understands this Agreement, is fully aware of its legal effect, and has entered into it freely, voluntarily and knowingly based on his own judgment; (b) Employee is receiving consideration under this Agreement in addition to
anything of value to which Employee is already entitled; and (c) Employee has been advised to consult with an attorney at his own expense before signing this Agreement. 

19. Section 409A. The payments made under this Agreement are intended to comply with, or be exempt from,
Section 409A of the Internal Revenue Code of 1986, as amended, and applicable guidance issued thereunder (“Section 409A”). Payments made under this Agreement will be interpreted and construed, to the extent possible, to be
distributed in the short-term deferral period, as defined under Treasury Regulation section 1.409A-1(b)(4), or the separation pay exemption, as provided in Treasury Regulation section 1.409A-1(b)(9). For purposes of this Agreement, each payment made and benefit provided under this Agreement is hereby designated as a separate payment, and will not collectively be treated as a single payment, as
provided in Treasury Regulation section 1.409A-2(b)(2)(iii). 
 20. Tax
Indemnification. It is understood between the parties that Employee has not relied upon any representation, express or implied, made by the Company or any of its representatives as to the tax consequences of this Agreement to Employee.
Employee agrees that any liability for state or federal income tax payments or penalties arising from this Agreement shall be Employee’s sole responsibility. Employee agrees to indemnify and to hold harmless the Company from any and all
actions, claims or demands brought by any tax or other authority based upon Employee’s tax obligations arising from payments to be made pursuant to this Agreement, and Employee agrees specifically to reimburse the Company for any taxes,
interest and penalties paid by the Company and for the costs, legal fees, and any other expenses incurred by the Company as a result of any such actions, claims or demands. 

21. Waiver. The failure by either party to insist upon strict compliance with any term or provision of this Agreement shall
not operate or be construed as a waiver of such term or provision. The waiver by either party of a breach of any term or provision of this Agreement must be in writing signed by such party in order to be binding and, further, shall not operate or be
construed as a waiver of a subsequent breach of the same provision by any party or of the breach of any other term or provision of this Agreement.  

By their authorized signatures below, Employee and the Company hereby enter into this Agreement.

court or administrative agency charged with enforcing the ADEA. The undersigned understands, however, that a court has discretion to decide whether any monetary award that the undersigned obtains in a court proceeding involving this Release would be
reduced by the amount of some or all of the consideration that the undersigned received for signing this Agreement. The undersigned also recognizes that the Company may be entitled to recover its costs and attorneys’ fees incurred in any such
court proceeding, as authorized by applicable law.

consistently taken the position that they have no liability whatsoever to the undersigned.
